Patient leaflet - Serevent Accuhaler
1 What Serevent Accuhaler is and what it is used for
- Serevent Accuhaler contains the medicine salmeterol. It is a ‘long-acting bronchodilator’. It helps the airways in the lungs to stay open. This makes it easier for air to get in and out. The effects are usually felt within 10 to 20 minutes and last for 12 hours or more.
- The doctor has prescribed it to help prevent breathing problems. These could be caused by asthma. Taking Serevent Accuhaler regularly will help prevent asthma attacks. This also includes asthma brought on by exercise or at night.
- Taking Serevent Accuhaler regularly will also help prevent breathing problems caused by other chest illnesses such as Chronic Obstructive Pulmonary Disease (COPD).
- Serevent Accuhaler helps to stop breathlessness and wheezing coming on. It does not work once you are breathless or wheezy. If that happens, you need to use a fast-acting ‘reliever’ medicine, such as salbutamol.
- Serevent is supplied to you in an inhaler called the Accuhaler. You breathe the medicine directly into your lungs.
If you are being treated for asthma, you should always be given both a Serevent and a steroid inhaler to use together.
2 What you need to know before you use Serevent Accuhaler
Do not take Serevent Accuhaler if:
you are allergic (hypersensitive) to salmeterol xinafoate, or to the other ingredient lactose.
Take special care with Serevent Accuhaler
- If you are using Serevent for asthma your doctor will want to regularly check your symptoms.
- If your asthma or breathing gets worse tell your doctor straight away. You may find that you feel more wheezy, your chest feels tight more often or you may need to use more of your fast-acting ‘reliever’ medicine. If any of these happen, do not increase your number of puffs of Serevent. Your chest condition may be getting worse and you could become seriously ill. See your doctor as you may need a change in asthma treatment.
- Once your asthma is well controlled your doctor may consider it appropriate to gradually reduce the dose of Serevent.
- If you have been prescribed Serevent for your asthma, continue to use any other asthma medication you are already taking. These could include a steroid inhaler or steroid tablets. Continue taking the same doses as before, unless your doctor tells you otherwise. Do this even if you feel much better. Do not stop taking your steroid inhaler (or any steroid tablets) when you start using Serevent.
- Your doctor may want to check your health regularly if you have an overactive thyroid gland, diabetes mellitus (Serevent may increase your blood sugar) or heart disease, including an irregular or fast heartbeat.
Other medicines and Serevent
Tell your doctor if you are taking or have recently taken any other medicines. This includes those for asthma or any other medicines obtained without a prescription. This is because Serevent may not be suitable to be taken with other medicines.
- Inform your doctor before using Serevent if you are currently being treated for any fungal infections with medicines containing ketoconazole or itraconazole, or if you are being treated for HIV with ritonavir. These medicines may increase the risk of you experiencing side effects with Serevent, including irregular heart beats, or may make side effects worse.
- Beta-blockers should be avoided when taking Serevent, unless your doctor tells you to take them. Beta-blockers, including atenolol, propranolol and sotalol, are mostly used for high blood pressure or other heart conditions. Tell your doctor if you are taking beta-blockers or have recently been prescribed beta-blockers as they may reduce or abolish the effects of salmeterol.
- Serevent can reduce the amount of potassium in your blood. If this happens you may notice an uneven heartbeat, muscle weakness or cramp. This is more likely to happen if you take Serevent with some medicines used to treat high blood pressure (diuretics - water tablets) and other medicines used to treat breathing problems such as theophylline or steroids. Your doctor may ask for you to have blood tests to check the amount of potassium in your blood. If you have any concerns discuss them with your doctor.
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Driving and using machines
The possible side effects associated with Serevent are unlikely to affect your ability to drive or use machines.

Using your inhaler
To open your Serevent
1
Accuhaler, hold the
outer case in one hand and put the thumb of your other hand on the thumbgrip.
Push your thumb away
from you as far as it will go.
You will hear a click. This will open a small hole in the mouthpiece.
2
Hold your Serevent
Accuhaler with the
mouthpiece towards you.
You can hold it in either your right or left hand. Slide the lever away from you as far as it will go. You will hear a click.
This places a dose of your medicine in the mouthpiece.
Every time the lever is pushed back a blister is opened inside and the powder made ready for you to inhale. Do not play with the lever as this opens the blisters and wastes medicine.
Hold the Serevent Accuhaler away from your mouth, breathe out as far as is comfortable.
3
Do not breathe into your Serevent Accuhaler.
Put the mouthpiece to your lips; breathe in steadily and deeply
4
Through the Serevent
Accuhaler, not through your
nose. Remove the Serevent
Accuhaler from your mouth.
Hold your breath for about
10 seconds or for as
long as is comfortable.
Breathe out slowly.
You may not be able to taste or feel the
powder on your tongue, even if you have
used the Serevent Accuhaler correctly.
Afterwards rinse your mouth with water and s spit it out. This may help to stop you getting thrush and being hoarse.

To close the Serevent Accuhaler, slide
the thumbgrip back towards
you, as far as it will go. You
will hear a click. The lever
will return to its original
position and is reset.
Your Serevent Accuhaler is now ready for you to use again.
Check with your doctor or pharmacist if you are not sure if you used your Serevent Accuhaler correctly.
Cleaning your inhaler
Wipe the mouthpiece of the Serevent Accuhaler with a dry tissue to clean it.
If you use more Serevent than you should
It is important to use the inhaler as instructed. If you accidentally take a larger dose than recommended, talk to your doctor or pharmacist. You may notice your heart beating faster than usual and that you feel shaky and/or dizzy. You may also have a headache, muscle weakness and aching joints.
If you forget to use Serevent
Do not take a double dose to make up for a missed dose. Just take your next dose at the usual time.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
