1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis – for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infant (including full-term
newborn babies) as preventive treatment in exceptional circumstances – for example, if there is a global epidemic of flu (a flu pandemic ) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.
Information about some of the ingredients of Tamiflu
This medicine contains less than 1 mmol sodium (23 mg) per capsule, that is to say essentially ‘sodium-free’.
3. How to take Tamiflu
Take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Take Tamiflu as soon as possible, ideally within two days of the flu symptoms starting.
The recommended doses
For treating flu , take two doses daily. It is usually convenient to take one dose in the morning and one in the evening. It is important to complete the whole 5-day course , even if you start to feel better quickly.
For patients with a weak immune system, treatment will continue for 10 days.
For preventing flu or after being exposed to an infected person, take one dose daily for 10 days. It is best to take this in the mornings with breakfast.
In special situations, such as widespread flu or for patients with a weak immune system, treatment will continue for up to 6 or 12 weeks.
The recommended dose is based on the patient’s body weight. You must use the amount of oral capsules or suspension prescribed by the doctor.

Method of administration
Swallow the capsules whole with water. Do not break or chew the capsules.
Tamiflu can be taken with or without food, although taking it with food can reduce the chance of feeling or being sick (nausea or vomiting).
People who find it hard to take capsules can use a liquid medicine, Tamiflu oral suspension. If you need Tamiflu oral suspension, but it’s not available from your pharmacy, you can make a liquid form of Tamiflu from these capsules. See Making liquid Tamiflu at home , over the page.
If you take more Tamiflu than you should
Stop taking Tamiflu and contact a doctor or pharmacist immediately.
In most cases of overdose, people have not reported any side effects. When side effects were reported, they were similar to those from normal doses, as listed in section 4.
Overdose has been reported to have occurred more frequently when Tamiflu was given to children than to adults and adolescents. Caution should be exercised when preparing liquid Tamiflu for children and when administering Tamiflu capsules or liquid Tamiflu to children.
If you forget to take Tamiflu
Do not take a double dose to make up for a forgotten capsule.
If you stop taking Tamiflu
There are no side effects when you stop Tamiflu. But if Tamiflu is stopped earlier than your doctor told you, the symptoms of flu may come back. Always complete the course that your doctor prescribed.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Detailed information on this medicine is available on the European Medicines Agency web site:
Information for the user
For people who find it hard to take capsules, including very young children, there’s a liquid medicine, Tamiflu oral suspension.
If you need a liquid medicine, but it’s not available, a suspension can be made up at the pharmacy from Tamiflu capsules (see Information for healthcare professionals). This pharmacy preparation is the preferred option.
If the pharmacy preparation is not available either, you can make liquid Tamiflu from these capsules at home.
The dose is the same for treating or preventing flu. The difference is how often it is given.
Making liquid Tamiflu at home
- If you have the right capsule for the dose needed (a 30 mg or a 60 mg dose), you will open the capsule and stir its contents into one teaspoon (or less) of a suitable sweetened food product.
This is usually suitable for children over 1 year. See the upper set of instructions.
- If you need smaller doses, making liquid Tamiflu from capsules involves extra steps. This is suitable for younger children and babies: they usually need a Tamiflu dose of less than 30 mg. See the lower set of instructions.
Children 1 to 12 years
To make a 30 mg or a 60 mg dose,
you need:
- One or two 30 mg Tamiflu capsule(s)
- Sharp scissors
- One small bowl
- Teaspoon (5 ml spoon)
- Water
- Sweet food to hide the bitter taste of the powder.
Examples are: chocolate or cherry syrup, and dessert toppings such as caramel or fudge sauce. Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Check the dose is correct
To find the correct amount to use, find the patient’s weight on the left of the table.
Look at the right column to check the number of capsules you will need to give the patient for a single dose. The amount is the same whether treating or preventing flu.
30 mg dose | ROCHE 30 mg |
60 mg dose | I™ T |
You should use only 30 mg capsules for 30 mg and 60 mg doses. Do not try to make a 45 mg or 75 mg dose by using the contents of 30 mg capsules. Use the appropriate size capsule instead.
Weight | Dose of Tamiflu | Number of 30 mg capsules |
Up to 15 kg | 30 mg | 1 capsule |
More than 15 kg up to 23 kg | 45 mg | Do not use 30 mg capsules |
More than 23 kg up to 40 kg | 60 mg | 2 capsules |
Step 2: Pour all the powder into a bowl
Hold a 30 mg capsule upright over a bowl and carefully snip off the rounded tip with scissors.
Pour all of the powder into the bowl.
Open a second capsule for a 60 mg dose. Pour all of the powder into the bowl.
Be careful with the powder, because it may irritate your skin and eyes.
Step 3: Sweeten the powder and give the dose
Add a small amount – no more than one teaspoonful – of sweet food to the powder in the bowl.
This is to hide the bitter taste of the Tamiflu powder.
Stir the mixture well.
Give the whole contents of the bowl to the patient straight away.
If there is some mixture left in the bowl, rinse the bowl with a small amount of water and get the patient to drink it all.
Repeat this procedure every time you need to give the medicine.
Infants less than 1 year
To make a smaller single dose, you need:
- One 30 mg Tamiflu capsule
- Sharp scissors
- Two small bowls (use separate pairs of bowls for each child)
- One large oral dose dispenser to measure out water – a 5 or 10 ml dispenser
- One small oral dose dispenser showing measurements of 0.1 ml, to give the dose
- Teaspoon (5 ml spoon)
- Water
Sweet food to hide the bitter taste of the Tamiflu.
Examples are: chocolate or cherry syrup and dessert toppings such as caramel or fudge sauce.
Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Pour all the powder into a bowl
Hold a 30 mg capsule upright over one of the bowls and carefully snip off the rounded tip with scissors. Be careful with the powder: it may irritate your skin and eyes.
Pour all of the powder into the bowl, whatever the dose you are making.
The amount is the same whether you are treating or preventing flu.
Step 2: Add water to dilute the medicine
Use the larger dispenser to draw up 5 ml water.
Add the water to the powder in the bowl.
Stir the mixture with the teaspoon for about 2 minutes.
Don’t worry if not all of the powder dissolves. The undissolved powder is just inactive ingredients.
Step 3: Choose the correct amount for your child’s weight
Look up the child’s weight on the left side of the table.
The column on the right of the table shows how much of the liquid mixture you will need to draw up.
Infants less than 1 year (including full-term newborn babies)
Child’s weight (nearest) | How much mixture to draw up |
3 kg | 1.5 ml |
3.5 kg | 1.8 ml |
4 kg | 2.0 ml |
4.5 kg | 2.3 ml |
5 kg | 2.5 ml |
5.5 kg | 2.8 ml |
6 kg | 3.0 ml |
6.5 kg | 3.3 ml |
7 kg | 3.5 ml |
7.5 kg | 3.8 ml |
8 kg | 4.0 ml |
8.5 kg | 4.3 ml |
9 kg | 4.5 ml |
9.5 kg | 4.8 ml |
10 kg or more | 5.0 ml |
Step 4: Draw up the liquid mixture
Make sure you have the right size dispenser.
Draw up the correct amount of liquid mixture from the first bowl.
Draw it up carefully so as not to include air bubbles.
Gently squirt the correct dose into the second bowl.
Step 5: Sweeten and give to the child
Add a small amount – no more than one teaspoonful – of a sweet food to the second bowl. This is to hide the bitter taste of the Tamiflu.
Mix the sweet food and Tamiflu liquid well.
Give the whole contents of the second bowl (Tamiflu liquid mixture with sweet food added) to the child straight away.
If there is anything left in the second bowl , rinse the bowl with a small amount of water and get the child to drink it all. For children unable to drink from a bowl, spoon-feed or use a bottle to feed the child the remaining liquid.
Give the child something to drink.
Throw away any unused liquid left in the first bowl.
Repeat this procedure every time you need to give the medicine.
Information for healthcare professionals only
Patients who are unable to swallow capsules:
Commercially manufactured Tamiflu for oral suspension (6mg/ml) is the preferred product for paediatric and adult patients who have difficulties swallowing capsules or where lower doses are needed. In the event thatTamiflu powder for oral suspension is not available, the pharmacist may compound a suspension (6 mg/ml) from Tamiflu capsules. If the pharmacy compounded suspension is also not available, patients may prepare the suspension from capsules at home.
Oral dose dispensers (oral syringes) of appropriate volume and grading should be provided for administering the pharmacy compounded suspension, and for the procedures involved in the home preparation. In both cases, the correct volumes should preferably be marked on the dispensers. For home preparation, separate dispensers should be provided for taking the correct volume of water and for measuring the Tamiflu-water mixture. For measuring 5.0 ml of water, dispensers of 5 ml or 10 ml should be used.
The appropriate dispenser sizes for taking the correct volume of Tamiflu suspension (6 mg/ml) are shown below.
Infants less than 1 year (including full term new born babies) :
Dose of Tamiflu | Amount of Tamiflu suspension | Dispenser size to use (grading 0.1 ml) |
9 mg | 1.5 ml | 2.0 ml (or 3.0 ml) |
10 mg | 1.7 ml | 2.0 ml (or 3.0 ml) |
11.25 mg | 1.9 ml | 2.0 ml (or 3.0 ml) |
12.5 mg | 2.1 ml | 3.0 ml |
13.75 mg | 2.3 ml | 3.0 ml |
15 mg | 2.5 ml | 3.0 ml |
16.25 mg | 2.7 ml | 3.0 ml |

1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis – for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances – for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.

Detailed information on this medicine is available on the European Medicines Agency web site:
Information for the user
For people who find it hard to take capsules, including very young children, there’s a liquid medicine, Tamiflu oral suspension.
If you need a liquid medicine, but it’s not available, a suspension can be made up at the pharmacy from Tamiflu capsules (see Information for healthcare professionals). This pharmacy preparation is the preferred option.
If the pharmacy preparation is not available either, you can make liquid Tamiflu from these capsules at home.
The dose is the same for treating or preventing flu. The difference is how often it is given.
Making liquid Tamiflu at home
If you have the right capsule for the dose needed (a 45 mg dose), you will open the capsule and stir its contents into one teaspoon (or less) of a suitable sweetened food product. This is usually suitable for children over 1 year. See the upper set of instructions.
If you need smaller doses, making liquid Tamiflu from capsules involves extra steps. This is suitable for younger, lighter children and babies: they usually need a Tamiflu dose of less than 45 mg. See the lower set of instructions.
Children 1 to 12 years
To make a 45 mg dose, you need:
One 45 mg Tamiflu capsule
Sharp scissors
One small bowl
Teaspoon (5 ml spoon)
Water
Sweet food to hide the bitter taste of the powder.
Examples are chocolate or cherry syrup, and dessert toppings such as caramel or fudge sauce. Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Check the dose is correct
To find the correct amount to use, find the patient’s weight on the left of the table.
Look at the right column to check the number of capsules you will need to give the patient for a single dose. The amount is the same whether treating or preventing flu.
45 mg dose
roche. 45 mg
You should use only 45 mg capsules for 45 mg doses. Do not try to make a 30 mg, 60 mg or 75 mg dose by using the contents of 45 mg capsules. Use the appropriate size capsule instead.
Weight | Dose of Tamiflu | Number of 45 mg capsules |
Up to 15 kg | 30 mg | Do not use 45 mg capsules |
More than 15 kg up to 23 kg | 45 mg | 1 capsule |
More than 23 kg up to 40 kg | 60 mg | Do not use 45 mg capsules |
Step 2: Pour all the powder into a bowl
Hold a 45 mg capsule upright over a bowl and carefully snip off the rounded tip with scissors.
Pour all of the powder into the bowl.
Be careful with the powder, because it may irritate your skin and eyes.
Step 3: Sweeten the powder and give the dose
Add a small amount – no more than one teaspoonful – of sweet food to the powder in the bowl.
This is to hide the bitter taste of the Tamiflu powder.
Stir the mixture well.
Give the whole contents of the bowl to the patient straight away.
If there is some mixture left in the bowl, rinse the bowl with a small amount of water and get the patient to drink it all.
Repeat this procedure every time you need to give the medicine.
Infants less than 1 year
To make a smaller single dose, you need:
- One 45 mg Tamiflu capsule
- Sharp scissors
- Two small bowls (use separate pairs of bowls for each child)
- One large oral dose dispenser to measure out water – a 5 ml dispenser or 10 ml dispenser
- One small oral dose dispenser showing measurements of 0.1 ml, to give the dose
- Teaspoon (5 ml spoon)
- Water
- Sweet food to hide the bitter taste of the Tamiflu.
Examples are: chocolate or cherry syrup and dessert toppings such as caramel or fudge sauce.
Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Pour all the powder into a bowl
Hold a 45 mg capsule upright over one of the bowls and carefully snip off the rounded tip with scissors. Be careful with the powder: it may irritate your skin and eyes.
Pour all of the powder into the bowl, whatever the dose you are making.
The amount is the same whether you are treating or preventing flu.
Step 2: Add water to dilute the medicine
Use the larger dispenser draw up 7.5 ml water.
Add the water to the powder in the bowl.
Stir the mixture with the teaspoon for about 2 minutes.
Don’t worry if not all of the powder dissolves. The undissolved powder is just inactive ingredients.
Step 3: Choose the correct amount for your child’s weight
Look up the child’s weight on the left side of the table.
The column on the right of the table shows how much of the liquid mixture you will need to draw up.
Infants less than 1 year (including full term newborn babies)
Child’s weight (nearest) | How much mixture to draw up |
3 kg | 1.5 ml |
3.5 kg | 1.8 ml |
4 kg | 2.0 ml |
4.5 kg | 2.3 ml |
5 kg | 2.5 ml |
5.5 kg | 2.8 ml |
6 kg | 3.0 ml |
6.5 kg | 3.3 ml |
7 kg | 3.5 ml |
7.5 kg | 3.8 ml |
8 kg | 4.0 ml |
8.5 kg | 4.3 ml |
9 kg | 4.5 ml |
9.5 kg | 4.8 ml |
10 kg or more | 5.0 ml |
Step 4: Draw up the liquid mixture
Make sure you have the right size dispenser.
Draw up the correct amount of liquid mixture from the first bowl.
Draw it up carefully so as not to include air bubbles.
Gently squirt the correct dose into the second bowl.
Step 5: Sweeten and give to the child
Add a small amount – no more than one teaspoonful – of a sweet food to the second bowl. This is to hide the bitter taste of the Tamiflu.
Mix the sweet food and Tamiflu liquid well.
Give the whole contents of the second bowl (Tamiflu liquid mixture with sweet food added) to the child straight away.
If there is anything left in the second bowl , rinse the bowl with a small amount of water and get the child to drink it all. For children unable to drink from a bowl, spoon-feed or use a bottle to feed the child the remaining liquid.
Give the child something to drink.
Throw away any unused liquid left in the first bowl.
Repeat this procedure every time you need to give the medicine.
Information for healthcare professionals only
Patients who are unable to swallow capsules
Commercially manufactured Tamiflu for oral suspension (6mg/ml) is the preferred product for paediatric and adult patients who have difficulties swallowing capsules or where lower doses are needed. In the event thatTamiflu powder for oral suspension is not available, the pharmacist may compound a suspension (6 mg/ml) from Tamiflu capsules. If the pharmacy compounded suspension is also not available, patients may prepare the suspension from capsules at home.
Oral dose dispensers (oral syringes) of appropriate volume and grading should be provided for administering the pharmacy compounded suspension, and for the procedures involved in the home preparation. In both cases, the correct volumes should preferably be marked on the dispensers. For home preparation, separate dispensers should be provided for taking the correct volume of water and for measuring the Tamiflu-water mixture. For measuring 5.0 ml of water, dispensers of 5 ml or 10 ml should be used.
The appropriate dispenser sizes for taking the correct volume of Tamiflu suspension (6 mg/ml) are shown below.
Infants less than 1 year (including full term new born babies) :
Dose of Tamiflu | Amount of Tamiflu suspension | Dispenser size to use (grading 0.1 ml) |

6. Contents of the pack and other information
1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis – for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances – for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.
Information about some of the ingredients of Tamiflu
This medicine contains less than 1 mmol sodium (23 mg) per capsule, that is to say essentially ‘sodium-free’.

Overdose has been reported to have occurred more frequently when Tamiflu was given to children than to adults and adolescents. Caution should be exercised when preparing liquid Tamiflu for children and when administering Tamiflu capsules or liquid Tamiflu to children.
If you forget to take Tamiflu
Do not take a double dose to make up for a forgotten capsule.
If you stop taking Tamiflu
There are no side effects when you stop Tamiflu. But if Tamiflu is stopped earlier than your doctor told you, the symptoms of flu may come back. Always complete the course that your doctor prescribed.

Detailed information on this medicine is available on the European Medicines Agency web site:
Information for the user
For people who find it hard to take capsules, including very young children, there’s a liquid medicine, Tamiflu oral suspension.
If you need a liquid medicine, but it’s not available, a suspension can be made up at the pharmacy from Tamiflu capsules (see Information for healthcare professionals). This pharmacy preparation is the preferred option.
If the pharmacy preparation is not available either, you can make liquid Tamiflu from these capsules at home.
The dose is the same for treating or preventing flu. The difference is how often it is given.
Making liquid Tamiflu at home
- If you have the right capsule strength for the dose needed (a 75 mg dose), you will open the capsule and stir its contents into one teaspoon (or less) of a suitable sweetened food product. This is usually suitable for children over 1 year. See the upper set of instructions.
- If you need smaller doses, making liquid Tamiflu from capsules involves extra steps. This is suitable for younger children and babies: they usually need a Tamiflu dose of less than 30 mg. See the lower set of instructions.
Adults, adolescents 13 years and over, and children weighing 40 kg and over
To make a 75 mg dose, you need:
- One 75 mg Tamiflu capsule
- Sharp scissors
- One small bowl
- Teaspoon (5 ml spoon)
- Water
- Sweet food to hide the bitter taste of the powder.
Examples are: chocolate or cherry syrup, and dessert toppings such as caramel or fudge sauce. Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Check the dose is correct
To find the correct amount to use, find the patient’s weight on the left of the table.
Look at the right column to check the number of capsules you will need to give the patient for a single dose. The amount is the same whether treating or preventing flu.
You should use only 75 mg capsules for 75 mg doses. Do not try to make a 75 mg dose by using the contents of 30 mg or 45 mg capsules.
Weight | Dose of Tamiflu | Number of capsules |
40 kg and over | 75 mg | 1 capsule |
Not for children who weigh less than 40 kg
You will need to prepare a dose of less than 75 mg for children who weigh less than 40 kg. See below.
Step 2: Pour all the powder into a bowl
Hold a 75 mg capsule upright over a bowl and carefully snip off the rounded tip with scissors.
Pour all of the powder into the bowl.
Be careful with the powder, because it may irritate your skin and eyes.
Step 3: Sweeten the powder and give the dose
Add a small amount – no more than one teaspoonful – of sweet food to the powder in the bowl.
This is to hide the bitter taste of the Tamiflu powder.
Stir the mixture well.
Give the whole contents of the bowl to the patient straight away.
If there is some mixture left in the bowl, rinse the bowl with a small amount of water and get the patient to drink it all.
Repeat this procedure every time you need to give the medicine.
Infants less than 1 year, and children weighing less than 40 kg
To make a smaller single dose, you need:
- One 75 mg Tamiflu capsule
- Sharp scissors
- Two small bowls
- One large oral dose dispenser to measure out water – a 5 or 10 ml dispenser
- One small oral dose dispenser showing measurements of 0.1 ml, to give the dose
- Teaspoon (5 ml spoon)
- Water
Sweet food to hide the bitter taste of the Tamiflu.
Examples are: chocolate or cherry syrup and dessert toppings such as caramel or fudge sauce.
Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Pour all the powder into a bowl
Hold a 75 mg capsule upright over one of the bowls and carefully snip off the rounded tip with scissors. Be careful with the powder: it may irritate your skin and eyes.
Pour all of the powder into the bowl, whatever the dose you are making.
The amount is the same whether you are treating or preventing flu.
Step 2: Add water to dilute the medicine
Use the larger dispenser to draw up 12.5 ml water.
Add the water to the powder in the bowl.
Stir the mixture with the teaspoon for about 2 minutes.
Don’t worry if not all of the powder dissolves. The undissolved powder is just inactive ingredients.
Step 3: Choose the correct amount for your child’s weight
Look up the child’s weight on the left side of the table.
The column on the right of the table shows how much of the liquid mixture you will need to draw up.
nfants less than 1 year (including full-term newbo rn babies)
Child’s weight (nearest) | How much mixture to draw up |
3 kg | 1.5 ml |
3.5 kg | 1.8 ml |
4 kg | 2.0 ml |
4.5 kg | 2.3 ml |
5 kg | 2.5 ml |
5.5 kg | 2.8 ml |
6 kg | 3.0 ml |
6.5 kg | 3.3 ml |
7 kg | 3.5 ml |
7.5 kg | 3.8 ml |
8 kg | 4.0 ml |
8.5 kg | 4.3 ml |
9 kg | 4.5 ml |
9.5 kg | 4.8 ml |
10 kg or more | 5.0 ml |
Children 1 year or older, , weighing less than 40 kg.
Child’s weight (nearest) | How much mixture to draw up |
Up to 15 kg | 5.0 ml |
15 to 23 kg | 7.5 ml |
23 to 40 kg | 10.0 ml |
Step 4: Draw up the liquid mixture
Make sure you have the right size dispenser.
Draw up the correct amount of liquid mixture from the first bowl.
Draw it up carefully so as not to include air bubbles.
Gently squirt the correct dose into the second bowl.
Step 5: Sweeten and give to the child
Add a small amount – no more than one teaspoonful – of a sweet food to the second bowl. This is to hide the bitter taste of the Tamiflu.
Mix the sweet food and Tamiflu liquid well.
Give the whole contents of the second bowl (Tamiflu liquid mixture with sweet food added) to the child straight away.
If there is anything left in the second bowl , rinse the bowl with a small amount of water and get the child to drink it all. For children unable to drink from a bowl, spoon-feed or use a bottle to feed the child the remaining liquid.
Give the child something to drink.
Throw away any unused liquid left in the first bowl.
Repeat this procedure every time you need to give the medicine.
Information for healthcare professionals only
Patients who are unable to swallow capsules:
Commercially manufactured Tamiflu for oral suspension (6mg/ml) is the preferred product for paediatric and adult patients who have difficulties swallowing capsules or where lower doses are needed. In the event thatTamiflu powder for oral suspension is not available, the pharmacist may compound a suspension (6 mg/ml) from Tamiflu capsules. If the pharmacy compounded suspension is also not available, patients may prepare the suspension from capsules at home.
Oral dose dispensers (oral syringes) of appropriate volume and grading should be provided for administering the pharmacy compounded suspension, and for the procedures involved in the home preparation. In both cases, the correct volumes should preferably be marked on the dispensers. For home preparation, separate dispensers should be provided for taking the correct volume of water and for measuring the Tamiflu-water mixture. For measuring 12.5 ml of water a 10 ml dispenser should be used.
The appropriate dispenser sizes for taking the correct volume of Tamiflu suspension (6 mg/ml) are shown below.

6. Contents of the pack and other information
1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis – for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances – for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.
Important information about some of the ingredients of Tamiflu
Tamiflu contains sorbitol.
Sorbitol is a source of fructose. If your doctor has told you that you have an intolerance to some sugars or if you have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you take or receive this medicine.
Sorbitol may cause gastrointestinal discomfort and mild laxative effect.

-
10 ml oseltamivir suspension contains 1.7 g of sorbitol.
-
12.5 ml oseltamivir suspension contains 2.1 g of sorbitol.

-
5 ml oseltamivir suspension contains 2.5 mg of sodium benzoate.
-
7.5 ml oseltamivir suspension conains 3.75 mg of sodium benzoate.
-
10 ml oseltamivir suspension contains 5.0 mg of sodium benzoate.

3. How to take Tamiflu
Take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Always use the oral dispenser that is provided in the box and has markings indicating the dose in millilitres (ml).
Take Tamiflu as soon as possible, ideally within two days of the flu symptoms starting.
The recommended doses
For treating flu , take two doses daily. It is usually convenient to take one dose in the morning and one in the evening. It is important to complete the whole 5-day course , even if you start to feel better quickly.
For patients with a weak immune system, treatment will continue for 10 days.

Detailed information on this medicine is available on the European Medicines Agency web site:
Information for the user
For people who find it hard to take capsules, including very young children, there’s a liquid medicine, Tamiflu oral suspension.
If you need a liquid medicine, but it’s not available, a suspension can be made up at the pharmacy from Tamiflu capsules (see Information for healthcare professionals). This pharmacy preparation is the preferred option.
If the pharmacy preparation is not available either, you can make liquid Tamiflu from these capsules at home.
The dose is the same for treating or preventing flu. The difference is how often it is given.
Making liquid Tamiflu at home
- If you have the right capsule for the dose needed (a 30 mg or a 60 mg dose), you will open the capsule and stir its contents into one teaspoon (or less) of a suitable sweetened food product.
This is usually suitable for children over 1 year. See the upper set of instructions.
- If you need smaller doses, making liquid Tamiflu from capsules involves extra steps. This is suitable for younger children and babies: they usually need a Tamiflu dose of less than 30 mg. See the lower set of instructions.
Children 1 to 12 years
To make a 30 mg or a 60 mg dose,
you need:
- One or two 30 mg Tamiflu capsule(s)
- Sharp scissors
- One small bowl
- Teaspoon (5 ml spoon)
- Water
- Sweet food to hide the bitter taste of the powder.
Examples are: chocolate or cherry syrup, and dessert toppings such as caramel or fudge sauce. Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Check the dose is correct
To find the correct amount to use, find the patient’s weight on the left of the table.
Look at the right column to check the number of capsules you will need to give the patient for a single dose. The amount is the same whether treating or preventing flu.
30 mg dose | ROCHE 30 mg |
60 mg dose | I™ T |
You should use only 30 mg capsules for 30 mg and 60 mg doses. Do not try to make a 45 mg or 75 mg dose by using the contents of 30 mg capsules. Use the appropriate size capsule instead.
Weight | Dose of Tamiflu | Number of 30 mg capsules |
Up to 15 kg | 30 mg | 1 capsule |
More than 15 kg up to 23 kg | 45 mg | Do not use 30 mg capsules |
More than 23 kg up to 40 kg | 60 mg | 2 capsules |
Step 2: Pour all the powder into a bowl
Hold a 30 mg capsule upright over a bowl and carefully snip off the rounded tip with scissors.
Pour all of the powder into the bowl.
Open a second capsule for a 60 mg dose. Pour all of the powder into the bowl.
Be careful with the powder, because it may irritate your skin and eyes.
Step 3: Sweeten the powder and give the dose
Add a small amount - no more than one teaspoonful - of sweet food to the powder in the bowl.
This is to hide the bitter taste of the Tamiflu powder.
Stir the mixture well.
Give the whole contents of the bowl to the patient straight away.
If there is some mixture left in the bowl, rinse the bowl with a small amount of water and get the patient to drink it all.
Repeat this procedure every time you need to give the medicine.
Infants less than 1 year
To make a smaller single dose, you need:
- One 30 mg Tamiflu capsule
- Sharp scissors
- Two small bowls (use separate pairs of bowls for each child)
- One large oral dose dispenser to measure out water - a 5 or 10 ml dispenser
- One small oral dose dispenser showing measurements of 0.1 ml, to give the dose
- Teaspoon (5 ml spoon)
- Water
Sweet food to hide the bitter taste of the Tamiflu.
Examples are: chocolate or cherry syrup and dessert toppings such as caramel or fudge sauce.
Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Pour all the powder into a bowl
Hold a 30 mg capsule upright over one of the bowls and carefully snip off the rounded tip with scissors. Be careful with the powder: it may irritate your skin and eyes.
Pour all of the powder into the bowl, whatever the dose you are making.
The amount is the same whether you are treating or preventing flu.
Step 2: Add water to dilute the medicine
Use the larger dispenser to draw up 5 ml water.
Add the water to the powder in the bowl.
Stir the mixture with the teaspoon for about 2 minutes.
Don’t worry if not all of the powder dissolves. The undissolved powder is just inactive ingredients.
Step 3: Choose the correct amount for your child’s weight
Look up the child’s weight on the left side of the table.
The column on the right of the table shows how much of the liquid mixture you will need to draw up.
Infants less than 1 year (including full-term newborn babies)
Child’s weight (nearest) | How much mixture to draw up |
3 kg | 1.5 ml |
3.5 kg | 1.8 ml |
4 kg | 2.0 ml |
4.5 kg | 2.3 ml |
5 kg | 2.5 ml |
5.5 kg | 2.8 ml |
6 kg | 3.0 ml |
6.5 kg | 3.3 ml |
7 kg | 3.5 ml |
7.5 kg | 3.8 ml |
8 kg | 4.0 ml |
8.5 kg | 4.3 ml |
9 kg | 4.5 ml |
9.5 kg | 4.8 ml |
10 kg or more | 5.0 ml |
Step 4: Draw up the liquid mixture
Make sure you have the right size dispenser.
Draw up the correct amount of liquid mixture from the first bowl.
Draw it up carefully so as not to include air bubbles.
Gently squirt the correct dose into the second bowl.
Step 5: Sweeten and give to the child
Add a small amount - no more than one teaspoonful - of a sweet food to the second bowl. This is to hide the bitter taste of the Tamiflu.
Mix the sweet food and Tamiflu liquid well.
Give the whole contents of the second bowl (Tamiflu liquid mixture with sweet food added) to the child straight away.
If there is anything left in the second bowl , rinse the bowl with a small amount of water and get the child to drink it all. For children unable to drink from a bowl, spoon-feed or use a bottle to feed the child the remaining liquid.
Give the child something to drink.
Throw away any unused liquid left in the first bowl.
Repeat this procedure every time you need to give the medicine.
Information for healthcare professionals only
Patients who are unable to swallow capsules:
Commercially manufactured Tamiflu for oral suspension (6mg/ml) is the preferred product for paediatric and adult patients who have difficulties swallowing capsules or where lower doses are needed. In the event thatTamiflu powder for oral suspension is not available, the pharmacist may compound a suspension (6 mg/ml) from Tamiflu capsules. If the pharmacy compounded suspension is also not available, patients may prepare the suspension from capsules at home.
Oral dose dispensers (oral syringes) of appropriate volume and grading should be provided for administering the pharmacy compounded suspension, and for the procedures involved in the home preparation. In both cases, the correct volumes should preferably be marked on the dispensers. For home preparation, separate dispensers should be provided for taking the correct volume of water and for measuring the Tamiflu-water mixture. For measuring 5.0 ml of water, dispensers of 5 ml or 10 ml should be used.
The appropriate dispenser sizes for taking the correct volume of Tamiflu suspension (6 mg/ml) are shown below.
Infants less than 1 year (including full term new born babies) :
Dose of Tamiflu | Amount of Tamiflu suspension | Dispenser size to use (grading 0.1 ml) |
9 mg | 1.5 ml | 2.0 ml (or 3.0 ml) |
10 mg | 1.7 ml | 2.0 ml (or 3.0 ml) |
11.25 mg | 1.9 ml | 2.0 ml (or 3.0 ml) |
12.5 mg | 2.1 ml | 3.0 ml |
13.75 mg | 2.3 ml | 3.0 ml |
15 mg | 2.5 ml | 3.0 ml |
16.25 mg | 2.7 ml | 3.0 ml |

6. Contents of the pack and other information
1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis - for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances - for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.
Information about some of the ingredients of Tamiflu
This medicine contains less than 1 mmol sodium (23 mg) per capsule, that is to say essentially ‘sodium-free’.
3. How to take Tamiflu
Take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Take Tamiflu as soon as possible, ideally within two days of the flu symptoms starting.
The recommended doses
For treating flu , take two doses daily. It is usually convenient to take one dose in the morning and one in the evening. It is important to complete the whole 5-day course , even if you start to feel better quickly.
For patients with a weak immune system, treatment will continue for 10 days.
For preventing flu or after being exposed to an infected person, take one dose daily for 10 days. It is best to take this in the mornings with breakfast.
In special situations, such as widespread flu or for patients with a weak immune system, treatment will continue for up to 6 or 12 weeks.
The recommended dose is based on the patient’s body weight. You must use the amount of oral capsules or suspension prescribed by the doctor.

Infants less than 1 year (0 to 12 months)
Giving Tamiflu to infants less than 1 year old for preventing flu during flu pandemic should be based upon the judgment of a doctor after considering the potential benefit versus any potential risk to the infant.

**mg per kg = mg for each kilogram of the infant’s body weight. For example:
If a 6-month-old weighs 8 kg, the dose is
8 kg x 3mg per kg = 24 mg
Method of administration
Swallow the capsules whole with water. Do not break or chew the capsules.
Tamiflu can be taken with or without food, although taking it with food can reduce the chance of feeling or being sick (nausea or vomiting).
People who find it hard to take capsules can use a liquid medicine, Tamiflu oral suspension. If you need Tamiflu oral suspension, but it’s not available from your pharmacy, you can make a liquid form of Tamiflu from these capsules. See Making liquid Tamiflu at home , over the page.
If you take more Tamiflu than you should
Stop taking Tamiflu and contact a doctor or pharmacist immediately.
In most cases of overdose, people have not reported any side effects. When side effects were reported, they were similar to those from normal doses, as listed in section 4.
Overdose has been reported to have occurred more frequently when Tamiflu was given to children than to adults and adolescents. Caution should be exercised when preparing liquid Tamiflu for children and when administering Tamiflu capsules or liquid Tamiflu to children.
If you forget to take Tamiflu
Do not take a double dose to make up for a forgotten capsule.
If you stop taking Tamiflu
There are no side effects when you stop Tamiflu. But if Tamiflu is stopped earlier than your doctor told you, the symptoms of flu may come back. Always complete the course that your doctor prescribed.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Detailed information on this medicine is available on the European Medicines Agency web site:
Information for the user
For people who find it hard to take capsules, including very young children, there’s a liquid medicine, Tamiflu oral suspension.
If you need a liquid medicine, but it’s not available, a suspension can be made up at the pharmacy from Tamiflu capsules (see Information for healthcare professionals). This pharmacy preparation is the preferred option.
If the pharmacy preparation is not available either, you can make liquid Tamiflu from these capsules at home.
The dose is the same for treating or preventing flu. The difference is how often it is given.
Making liquid Tamiflu at home
If you have the right capsule for the dose needed (a 45 mg dose), you will open the capsule and stir its contents into one teaspoon (or less) of a suitable sweetened food product. This is usually suitable for children over 1 year. See the upper set of instructions.
If you need smaller doses, making liquid Tamiflu from capsules involves extra steps. This is suitable for younger, lighter children and babies: they usually need a Tamiflu dose of less than 45 mg. See the lower set of instructions.
Children 1 to 12 years
To make a 45 mg dose, you need:
One 45 mg Tamiflu capsule
Sharp scissors
One small bowl
Teaspoon (5 ml spoon)
Water
Sweet food to hide the bitter taste of the powder.
Examples are chocolate or cherry syrup, and dessert toppings such as caramel or fudge sauce. Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Check the dose is correct
To find the correct amount to use, find the patient’s weight on the left of the table.
Look at the right column to check the number of capsules you will need to give the patient for a single dose. The amount is the same whether treating or preventing flu.
45 mg dose
roche. 45 mg
You should use only 45 mg capsules for 45 mg doses. Do not try to make a 30 mg, 60 mg or 75 mg dose by using the contents of 45 mg capsules. Use the appropriate size capsule instead.
Weight | Dose of Tamiflu | Number of 45 mg capsules |
Up to 15 kg | 30 mg | Do not use 45 mg capsules |
More than 15 kg up to 23 kg | 45 mg | 1 capsule |
More than 23 kg up to 40 kg | 60 mg | Do not use 45 mg capsules |
Step 2: Pour all the powder into a bowl
Hold a 45 mg capsule upright over a bowl and carefully snip off the rounded tip with scissors.
Pour all of the powder into the bowl.
Be careful with the powder, because it may irritate your skin and eyes.
Step 3: Sweeten the powder and give the dose
Add a small amount - no more than one teaspoonful - of sweet food to the powder in the bowl.
This is to hide the bitter taste of the Tamiflu powder.
Stir the mixture well.
Give the whole contents of the bowl to the patient straight away.
If there is some mixture left in the bowl, rinse the bowl with a small amount of water and get the patient to drink it all.
Repeat this procedure every time you need to give the medicine.
Infants less than 1 year
To make a smaller single dose, you need:
- One 45 mg Tamiflu capsule
- Sharp scissors
- Two small bowls (use separate pairs of bowls for each child)
- One large oral dose dispenser to measure out water - a 5 ml dispenser or 10 ml dispenser
- One small oral dose dispenser showing measurements of 0.1 ml, to give the dose
- Teaspoon (5 ml spoon)
- Water
- Sweet food to hide the bitter taste of the Tamiflu.
Examples are: chocolate or cherry syrup and dessert toppings such as caramel or fudge sauce.
Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Pour all the powder into a bowl
Hold a 45 mg capsule upright over one of the bowls and carefully snip off the rounded tip with scissors. Be careful with the powder: it may irritate your skin and eyes.
Pour all of the powder into the bowl, whatever the dose you are making.
The amount is the same whether you are treating or preventing flu.
Step 2: Add water to dilute the medicine
Use the larger dispenser draw up 7.5 ml water.
Add the water to the powder in the bowl.
Stir the mixture with the teaspoon for about 2 minutes.
Don’t worry if not all of the powder dissolves. The undissolved powder is just inactive ingredients.
Step 3: Choose the correct amount for your child’s weight
Look up the child’s weight on the left side of the table.
The column on the right of the table shows how much of the liquid mixture you will need to draw up.
Infants less than 1 year (including full term newborn babies)
Child’s weight (nearest) | How much mixture to draw up |
3 kg | 1.5 ml |
3.5 kg | 1.8 ml |
4 kg | 2.0 ml |
4.5 kg | 2.3 ml |
5 kg | 2.5 ml |
5.5 kg | 2.8 ml |
6 kg | 3.0 ml |
6.5 kg | 3.3 ml |
7 kg | 3.5 ml |
7.5 kg | 3.8 ml |
8 kg | 4.0 ml |
8.5 kg | 4.3 ml |
9 kg | 4.5 ml |
9.5 kg | 4.8 ml |
10 kg or more | 5.0 ml |
Step 4: Draw up the liquid mixture
Make sure you have the right size dispenser.
Draw up the correct amount of liquid mixture from the first bowl.
Draw it up carefully so as not to include air bubbles.
Gently squirt the correct dose into the second bowl.
Step 5: Sweeten and give to the child
Add a small amount - no more than one teaspoonful - of a sweet food to the second bowl. This is to hide the bitter taste of the Tamiflu.
Mix the sweet food and Tamiflu liquid well.
Give the whole contents of the second bowl (Tamiflu liquid mixture with sweet food added) to the child straight away.
If there is anything left in the second bowl , rinse the bowl with a small amount of water and get the child to drink it all. For children unable to drink from a bowl, spoon-feed or use a bottle to feed the child the remaining liquid.
Give the child something to drink.
Throw away any unused liquid left in the first bowl.
Repeat this procedure every time you need to give the medicine.
Information for healthcare professionals only
Patients who are unable to swallow capsules
Commercially manufactured Tamiflu for oral suspension (6mg/ml) is the preferred product for paediatric and adult patients who have difficulties swallowing capsules or where lower doses are needed. In the event thatTamiflu powder for oral suspension is not available, the pharmacist may compound a suspension (6 mg/ml) from Tamiflu capsules. If the pharmacy compounded suspension is also not available, patients may prepare the suspension from capsules at home.
Oral dose dispensers (oral syringes) of appropriate volume and grading should be provided for administering the pharmacy compounded suspension, and for the procedures involved in the home preparation. In both cases, the correct volumes should preferably be marked on the dispensers. For home preparation, separate dispensers should be provided for taking the correct volume of water and for measuring the Tamiflu-water mixture. For measuring 5.0 ml of water, dispensers of 5 ml or 10 ml should be used.
The appropriate dispenser sizes for taking the correct volume of Tamiflu suspension (6 mg/ml) are shown below.
Infants less than 1 year (including full term new born babies) :
Dose of Tamiflu | Amount of Tamiflu suspension | Dispenser size to use (grading 0.1 ml) |
9 mg | 1.5 ml | 2.0 ml (or 3.0 ml) |
10 mg | 1.7 ml | 2.0 ml (or 3.0 ml) |
11.25 mg | 1.9 ml | 2.0 ml (or 3.0 ml) |
12.5 mg | 2.1 ml | 3.0 ml |
13.75 mg | 2.3 ml | 3.0 ml |
15 mg | 2.5 ml | 3.0 ml |

Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
- Keep this leaflet. You may need to read it again.
- If you have further questions, ask your doctor or pharmacist.
- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.

6. Contents of the pack and other information
1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis - for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances - for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.
Information about some of the ingredients of Tamiflu
This medicine contains less than 1 mmol sodium (23 mg) per capsule, that is to say essentially ‘sodium-free’.
3. How to take Tamiflu
Take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Take Tamiflu as soon as possible, ideally within two days of the flu symptoms starting.
The recommended doses
For treating flu , take two doses daily. It is usually convenient to take one dose in the morning and one in the evening. It is important to complete the whole 5-day course , even if you start to feel better quickly.
For patients with a weak immune system, treatment will continue for 10 days.
For preventing flu or after being exposed to an infected person, take one dose daily for 10 days. It is best to take this in the mornings with breakfast.
In special situations, such as widespread flu or for patients with a weak immune system, treatment will continue for up to 6 or 12 weeks.
The recommended dose is based on the patient’s body weight. You must use the amount of oral capsules or suspension prescribed by the doctor.

Infants less than 1 year (0 to 12 months)
Giving Tamiflu to infants less than 1 year old for preventing flu during flu pandemic should be based upon the judgment of a doctor after considering the potential benefit versus any potential risk to the infant.
Body weight | Treating flu: dose for 5 days | Treating flu (Immunocompromised Patients): dose for 10 days * | Preventing flu: dose for 10 days |
3 kg to 10+ kg, | 3 mg per kg body weight**, twice daily | 3 mg per kg body weight**, twice daily | 3 mg per kg**, once daily |
* For infants with a weak immune system, treatment is for 10 days.
**mg per kg = mg for each kilogram of the infant’s body weight. For example:
If a 6-month-old weighs 8 kg, the dose is
8 kg x 3mg per kg = 24 mg
Method of administration
Swallow the capsules whole with water. Do not break or chew the capsules.
Tamiflu can be taken with or without food, although taking it with food can reduce the chance of feeling or being sick (nausea or vomiting).
People who find it hard to take capsules can use a liquid medicine, Tamiflu oral suspension. If you need Tamiflu oral suspension, but it’s not available from your pharmacy, you can make a liquid form of Tamiflu from these capsules. See Making liquid Tamiflu at home , over the page.
If you take more Tamiflu than you should
Stop taking Tamiflu and contact a doctor or pharmacist immediately.
In most cases of overdose, people have not reported any side effects. When side effects were reported, they were similar to those from normal doses, as listed in section 4.
Overdose has been reported to have occurred more frequently when Tamiflu was given to children than to adults and adolescents. Caution should be exercised when preparing liquid Tamiflu for children and when administering Tamiflu capsules or liquid Tamiflu to children.
If you forget to take Tamiflu
Do not take a double dose to make up for a forgotten capsule.
If you stop taking Tamiflu
There are no side effects when you stop Tamiflu. But if Tamiflu is stopped earlier than your doctor told you, the symptoms of flu may come back. Always complete the course that your doctor prescribed.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

Information for the user
For people who find it hard to take capsules, including very young children, there’s a liquid medicine, Tamiflu oral suspension.
If you need a liquid medicine, but it’s not available, a suspension can be made up at the pharmacy from Tamiflu capsules (see Information for healthcare professionals). This pharmacy preparation is the preferred option.
If the pharmacy preparation is not available either, you can make liquid Tamiflu from these capsules at home.
The dose is the same for treating or preventing flu. The difference is how often it is given.

- If you have the right capsule strength for the dose needed (a 75 mg dose), you will open the capsule and stir its contents into one teaspoon (or less) of a suitable sweetened food product. This is usually suitable for children over 1 year. See the upper set of instructions.
- If you need smaller doses, making liquid Tamiflu from capsules involves extra steps. This is suitable for younger children and babies: they usually need a Tamiflu dose of less than 30 mg. See the lower set of instructions.
Adults, adolescents 13 years and over, and children weighing 40 kg and over
To make a 75 mg dose, you need:
- One 75 mg Tamiflu capsule
- Sharp scissors
- One small bowl
- Teaspoon (5 ml spoon)
- Water
- Sweet food to hide the bitter taste of the powder.
Examples are: chocolate or cherry syrup, and dessert toppings such as caramel or fudge sauce. Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Check the dose is correct
To find the correct amount to use, find the patient’s weight on the left of the table.
Look at the right column to check the number of capsules you will need to give the patient for a single dose. The amount is the same whether treating or preventing flu.
You should use only 75 mg capsules for 75 mg doses. Do not try to make a 75 mg dose by using the contents of 30 mg or 45 mg capsules.
Weight | Dose of Tamiflu | Number of capsules |
40 kg and over | 75 mg | 1 capsule |
Not for children who weigh less than 40 kg
You will need to prepare a dose of less than 75 mg for children who weigh less than 40 kg. See below.
Step 2: Pour all the powder into a bowl
Hold a 75 mg capsule upright over a bowl and carefully snip off the rounded tip with scissors.
Pour all of the powder into the bowl.
Be careful with the powder, because it may irritate your skin and eyes.
Step 3: Sweeten the powder and give the dose
Add a small amount - no more than one teaspoonful - of sweet food to the powder in the bowl.
This is to hide the bitter taste of the Tamiflu powder.
Stir the mixture well.
Give the whole contents of the bowl to the patient straight away.
If there is some mixture left in the bowl, rinse the bowl with a small amount of water and get the patient to drink it all.
Repeat this procedure every time you need to give the medicine.
Infants less than 1 year, and children weighing less than 40 kg
To make a smaller single dose, you need:
- One 75 mg Tamiflu capsule
- Sharp scissors
- Two small bowls
- One large oral dose dispenser to measure out water - a 5 or 10 ml dispenser
- One small oral dose dispenser showing measurements of 0.1 ml, to give the dose
- Teaspoon (5 ml spoon)
- Water
Sweet food to hide the bitter taste of the Tamiflu.
Examples are: chocolate or cherry syrup and dessert toppings such as caramel or fudge sauce.
Or you can make sugar water: mix a teaspoon of water with three-quarters (3/4) of a teaspoon of sugar.
Step 1: Pour all the powder into a bowl
Hold a 75 mg capsule upright over one of the bowls and carefully snip off the rounded tip with scissors. Be careful with the powder: it may irritate your skin and eyes.
Pour all of the powder into the bowl, whatever the dose you are making.
The amount is the same whether you are treating or preventing flu.
Step 2: Add water to dilute the medicine
Use the larger dispenser to draw up 12.5 ml water.
Add the water to the powder in the bowl.
Stir the mixture with the teaspoon for about 2 minutes.
Don’t worry if not all of the powder dissolves. The undissolved powder is just inactive ingredients.
Step 3: Choose the correct amount for your child’s weight
Look up the child’s weight on the left side of the table.
The column on the right of the table shows how much of the liquid mixture you will need to draw up.
nfants less than 1 year (including full-term newbo rn babies)
Child’s weight (nearest) | How much mixture to draw up |
3 kg | 1.5 ml |
3.5 kg | 1.8 ml |
4 kg | 2.0 ml |
4.5 kg | 2.3 ml |
5 kg | 2.5 ml |
5.5 kg | 2.8 ml |
6 kg | 3.0 ml |
6.5 kg | 3.3 ml |
7 kg | 3.5 ml |
7.5 kg | 3.8 ml |
8 kg | 4.0 ml |
8.5 kg | 4.3 ml |
9 kg | 4.5 ml |
9.5 kg | 4.8 ml |
10 kg or more | 5.0 ml |
Children 1 year or older, , weighing less than 40 kg.
Child’s weight (nearest) | How much mixture to draw up |
Up to 15 kg | 5.0 ml |
15 to 23 kg | 7.5 ml |
23 to 40 kg | 10.0 ml |
Step 4: Draw up the liquid mixture
Make sure you have the right size dispenser.
Draw up the correct amount of liquid mixture from the first bowl.
Draw it up carefully so as not to include air bubbles.
Gently squirt the correct dose into the second bowl.
Step 5: Sweeten and give to the child
Add a small amount - no more than one teaspoonful - of a sweet food to the second bowl. This is to hide the bitter taste of the Tamiflu.
Mix the sweet food and Tamiflu liquid well.
Give the whole contents of the second bowl (Tamiflu liquid mixture with sweet food added) to the child straight away.
If there is anything left in the second bowl , rinse the bowl with a small amount of water and get the child to drink it all. For children unable to drink from a bowl, spoon-feed or use a bottle to feed the child the remaining liquid.
Give the child something to drink.
Throw away any unused liquid left in the first bowl.
Repeat this procedure every time you need to give the medicine.
Information for healthcare professionals only
Patients who are unable to swallow capsules:
Commercially manufactured Tamiflu for oral suspension (6mg/ml) is the preferred product for paediatric and adult patients who have difficulties swallowing capsules or where lower doses are needed. In the event thatTamiflu powder for oral suspension is not available, the pharmacist may compound a suspension (6 mg/ml) from Tamiflu capsules. If the pharmacy compounded suspension is also not available, patients may prepare the suspension from capsules at home.
Oral dose dispensers (oral syringes) of appropriate volume and grading should be provided for administering the pharmacy compounded suspension, and for the procedures involved in the home preparation. In both cases, the correct volumes should preferably be marked on the dispensers. For home preparation, separate dispensers should be provided for taking the correct volume of water and for measuring the Tamiflu-water mixture. For measuring 12.5 ml of water a 10 ml dispenser should be used.
The appropriate dispenser sizes for taking the correct volume of Tamiflu suspension (6 mg/ml) are shown below.

Package Leaflet: Information for the user
Tamiflu 6 mg/ml powder for oral suspension oseltamivir
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
- Keep this leaflet. You may need to read it again.
- If you have further questions, ask your doctor or pharmacist.
- This medicine has been prescribed for you only. Do not pass it on to others. It may harm them, even if their signs of illness are the same as yours.
- If you get any of the side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. See section 4.

1. What Tamiflu is and what it is used for
2. What you need to know before you take Tamiflu

5. How to store Tamiflu
6. Contents of the pack and other information
1. What Tamiflu is and what it is used for
- Tamiflu is used for adults, adolescents, children and infants (including full-term newborn babies) for treating flu (influenza). It can be used when you have flu symptoms, and the flu virus is known to be going round in your community.
- Tamiflu can also be prescribed for adults, adolescents, children and infants above 1 year of age for preventing flu, on a case-by-case basis - for instance, if you have been in contact with someone who has flu.
- Tamiflu may be prescribed for adults, adolescents, children and infants (including full-term newborn babies) as preventive treatment in exceptional circumstances - for example, if there is a global epidemic of flu (a flu pandemic) and the seasonal flu vaccine may not provide sufficient protection.
Tamiflu contains oseltamivir , which belongs to a group of medicines named neuraminidase inhibitors. These medicines prevent the flu virus from spreading inside the body. They help to ease or prevent the symptoms of the flu virus infection.
Influenza, usually called flu, is an infection caused by a virus. The signs of flu often include a sudden fever (more than 37.8 °C), cough, runny or stuffy nose, headaches, muscle aches and extreme tiredness. These symptoms can also be caused by other infections. True influenza infection only occurs during annual outbreaks (epidemics ) when flu viruses are spreading in the local community. Outside epidemic periods, flu-like symptoms are usually caused by a different type of illness.
2. What you need to know before you take Tamiflu
Do not take Tamiflu:
- if you are allergic (hypersensitive) to oseltamivir or any of the other ingredients of Tamiflu listed in section 6.
Talk to your doctor if this applies to you. Do not take Tamiflu.
Warnings and precautions:
Before you take Tamiflu, make sure the prescribing doctor knows
- if you are allergic to other medicines
- if you have problems with your kidneys. If so, your dose may need adjustment
- if you have a severe medical condition, which may require immediate hospitalisation
- if your immune system is not working
- if you have chronic heart disease or respiratory disease.
During treatment with Tamiflu, tell a doctor immediately :
- if you notice changes in behaviour or mood (neuropsychiatric events), especially in children and adolescents). These may be signs of rare but serious side effects.
Tamiflu is not a flu vaccine
Tamiflu is not a vaccine: it treats infection, or prevents the flu virus spreading. A vaccine gives you antibodies against the virus. Tamiflu will not change the effectiveness of a flu vaccine, and you might be prescribed both by your doctor.
Other medicines and Tamiflu
Tell your doctor or pharmacist if you are taking any other medicines, or have recently taken any. This includes medicines obtained without a prescription. The following medicines are particularly important:
- chlorpropamide (used to treat diabetes)
- methotrexate (used to treat e.g. rheumatoid arthritis)
- phenylbutazone (used to treat pain and inflammation)
- probenecid (used to treat gout)
Pregnancy and breast-feeding
You must tell your doctor if you are pregnant, if you think you are pregnant or if you are trying to get pregnant so that your doctor can decide if Tamiflu is right for you.
The effects on breast-fed infants are unknown. You must tell your doctor if you are breast-feeding so that your doctor can decide if Tamiflu is right for you.
Ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
Tamiflu has no effect on your ability to drive or use machines.
Important information about some of the ingredients of Tamiflu
Tamiflu contains sorbitol.
Sorbitol is a source of fructose. If your doctor has told you that you have an intolerance to some sugars or if you have been diagnosed with hereditary fructose intolerance (HFI), a rare genetic disorder in which a person cannot break down fructose, talk to your doctor before you take or receive this medicine.
Sorbitol may cause gastrointestinal discomfort and mild laxative effect.
5 ml oseltamivir suspension contains 0.9 g of sorbitol.
7.5 ml oseltamivir suspension contains 1.3 g of sorbitol.
10 ml oseltamivir suspension contains 1.7 g of sorbitol.
12.5 ml oseltamivir suspension contains 2.1 g of sorbitol.
Tamiflu contains sodium benzoate.
Sodium benzoate (E211) may increase jaundice (yellowing of the skin and eyes) in newborn babies (up to 4 weeks old).
5 ml oseltamivir suspension contains 2.5 mg of sodium benzoate.
7.5 ml oseltamivir suspension conains 3.75 mg of sodium benzoate.
10 ml oseltamivir suspension contains 5.0 mg of sodium benzoate.
12.5 ml oseltamivir suspension contains 6.25 mg of sodium benzoate.
This medicine contains less than 1 mmol sodium (23 mg) per single dose (based on a maximum dose of 75 mg), that is to say essentially ‘sodium-free’.
3. How to take Tamiflu
Take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Always use the oral dispenser that is provided in the box and has markings indicating the dose in millilitres (ml).
Take Tamiflu as soon as possible, ideally within two days of the flu symptoms starting.
The recommended doses
For treating flu , take two doses daily. It is usually convenient to take one dose in the morning and one in the evening. It is important to complete the whole 5-day course , even if you start to feel better quickly.
For patients with a weak immune system, treatment will continue for 10 days.
For preventing flu or after being exposed to an infected person, take one dose daily for 10 days. It is best to take this in the mornings with breakfast.
In special situations, such as widespread flu, or for patients with a weak immune system, treatment will continue for up to 6 or 12 weeks.
The recommended dose is based on the patient’s body weight. You must use the amount of Tamiflu prescribed by the doctor. The oral suspension can be used by people who find it hard to take capsules. See the instructions overleaf to make up and give a dose.
