Patient leaflet - Lansoprazole 30 mg Oro-dispersible tablets

What Lansoprazole is and what it is used for

The active ingredient in Lansoprazole is lansoprazole, which is a proton pump inhibitor. Proton pump inhibitors reduce the amount of acid that your stomach makes.

Your doctor may prescribe Lansoprazole for the following indications:

-

Treatment of duodenal and stomach ulcer

-

Treatment of inflammation in your oesophagus (reflux oesophagitis)

-

Prevention of reflux oesophagitis

-

Treatment of heartburn and acid regurgitation

-

Treatment of infections caused by the bacteria

Helicobacter pylori when given in combination with antibiotic therapy

-

Treatment or prevention of duodenal or stomach ulcer in patients

requiring continued non- steroidal anti-inflammatory drugs (NSAID) treatment (NSAID treatment is used against pain or inflammation)

-

Treatment of Zollinger-Ellison syndrome.

Your doctor may have prescribed Lansoprazole for another indication or with a dose different from that which is written in this information leaflet. Please take your medicine in consultation with your doctor.

You must talk to a doctor if you do not feel better or if you feel worse after 14 days.

2.

What you need to know before you take Lansoprazole

Do not take Lansoprazole:

-

if you are allergic to lansoprazole or any of the other ingredients of this

medicine (listed in section 6).

Warnings and precautions

Please tell your doctor if you have serious liver disease. The doctor may have to adjust your dosage.

Your doctor may perform or have performed an additional investigation called an endoscopy in order to diagnose your condition and/or exclude malignant disease.

If severe or persistent diarrhoea occurs during the treatment with Lansoprazole contact your doctor immediately, as Lansoprazole has been associated with a small increase in infectious diarrhoea.

If your doctor has given you Lansoprazole in addition to other medicines intended for the treatment of Helicobacter pylori infection (antibiotics) or together with anti-inflammatory medicines to treat your pain or rheumatic disease: please also read the package leaflets of these medicines carefully.

If you take Lansoprazole for more than three months it is possible that the levels of magnesium in your blood may fall. Low levels of magnesium can be seen as fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness, increased heart rate. If you get any of these symptoms, please tell your doctor promptly. Low levels of magnesium can also lead to a reduction in potassium or calcium levels in the blood. Your doctor may decide to perform regular blood tests to monitor your levels of magnesium.

Taking a proton pump inhibitor like Lansoprazole, especially over a period of more than one year, may slightly increase your risk of fracture in the hip, wrist or spine. Tell your doctor if you have osteoporosis (reduced bone density) or if your doctor has told you that you are at risk of getting osteoporosis (for example, if you are taking steroids).

This medicine may affect the way that your body absorbs vitamin B12, particularly if you need to take it for a long time. Please contact your doctor if you notice any of the following symptoms, which could indicate low levels of vitamin B12:

-

Extreme tiredness or lack of energy

-

Pins and needles

-

Sore or red tongue, mouth ulcers

-

Muscle weakness

-

Disturbed vision

-

Problems with memory, confusion, depression

If you take Lansoprazole on a long-term basis (longer than 1 year) your doctor will probably keep you under regular surveillance. You should report any new and exceptional symptoms and circumstances whenever you see your doctor.

Talk to your doctor before taking Lansoprazole:

-

if you are due to have a specific blood test (Chromogranin A).

-

if you have ever had a skin reaction after treatment with a medicine

similar to Lansoprazole that reduces stomach acid.

Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with lansoprazole treatment. Stop using Lansoprazole and seek medical attention immediately if you notice any of the symptoms described in section 4.

If you get a rash on your skin, especially in areas exposed to the sun tell your doctor as soon as you can, as you may need to stop your treatment with Lansoprazole. Remember to also mention any other ill-effects like pain in your joints.

When taking lansoprazole, inflammation in your kidney may occur. Signs and symptoms may include decreased volume of urine or blood in your urine and/or hypersensitivity reactions such as fever, rash, and joint stiffness. You should report such signs to the treating physician.

Other medicines and Lansoprazole

Pregnancy, breast-feeding and fertility

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

Side effects such as dizziness, vertigo, tiredness and visual disturbances sometimes occur in patients taking Lansoprazole. If you experience side effects like these you should take caution as your ability to react may be decreased.

You alone are responsible to decide if you are in a fit condition to drive a motor vehicle or perform other tasks that demand increased concentration. Because of their effects or undesirable effects, one of the factors that can reduce your ability to do these things safely is your use of medicines.

Descriptions of these effects can be found in other sections. Read all the information in this leaflet for guidance.

Discuss with your doctor or pharmacist if you are unsure about anything.

Lansoprazole contains aspartame

Each Lansoprazole 15 mg tablet contains 4.5 mg aspartame.

Each Lansoprazole 30 mg tablet contains 9.0 mg aspartame.

Aspartame is a source of phenylalanine. Phenylalanine may be harmful if you have phenylketonuria (PKU), a rare genetic disorder in which phenylalanine builds up because the body cannot remove it properly.

3.

How to take Lansoprazole

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Place the tablet on your tongue and suck gently. The tablet rapidly dissolves in the mouth, releasing microgranules which you should swallow without chewing. You can also swallow the tablet whole with a glass of water.

Your doctor might instruct you to take the tablet with a syringe, in case you have serious difficulties with swallowing.

The following instructions should be followed if administered via syringe:

It is important that the appropriateness of the selected syringe is carefully tested.

-

Remove the plunger of the syringe (at least 5 mL syringe for the 15 mg tablet and 10 mL syringe for the 30 mg tablet)

-

Put the tablet into the barrel

-

Put the plunger back onto the syringe

-

For the 15 mg tablet: Draw 4 mL tap water into the syringe

-

For the 30 mg tablet: Draw 10 mL tap water into the syringe

-

Invert the syringe and draw an additional 1 mL of air into it

-

Shake the syringe gently for 10-20 seconds until the tablet is dispersed

-

The contents can be emptied directly into the mouth

-

Refill the syringe with 2-5 mL of tap water to flush the remnants out of the syringe into the mouth

If you are taking Lansoprazole once a day, try to take it at the same time each day. You may get best results if you take Lansoprazole first thing in the morning.

If you are taking Lansoprazole twice a day, you should have the first dose in the morning and the second dose in the evening.

The packaging has been printed with the days of the week to help you keep track of the medicines you have already taken.

The dose of Lansoprazole depends on your condition. The usual doses of Lansoprazole for adults are given below. Your doctor will sometimes prescribe you a different dose and will tell you how long your treatment will last.

If you stop taking Lansoprazole

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. If you think you may have any of the following serious side effects, stop taking this medicine and contact your doctor or go to your nearest hospital emergency room immediately.

-

Very rarely Lansoprazole may cause severe hypersensitivity (allergic)

reactions. Symptoms of a hypersensitivity reaction may include fever, rash, swollen face, swollen lymph nodes, swollen tongue or pharynx, difficulty to swallow, hives, difficulty to breath and sometimes a fall in blood pressure.

-

Very rarely, severe skin reactions that may be life threatening have

been reported with Lansoprazole. Symptoms include reddish patches on the trunk, the patches are target-like macules or circular, often with central blisters, skin peeling, ulcers of mouth, throat, nose, genitals and eyes. These serious skin rashes can be preceded by fever and flu-like symptoms [Stevens- Johnsons Syndrome (SJS), Toxic Epidermal Necrolysis (TEN)].

-

Widespread rash, high body temperature and enlarged lymph nodes

[Drug Reaction with Eosinophilia and Systemic Systems (DRESS, frequency not known)].

-

If you take Lansoprazole for more than three months it is possible

that the levels of magnesium in your blood may fall. Low levels of magnesium can be seen as fatigue, involuntary muscle contractions, disorientation, convulsions, dizziness, increased heart rate. If you get any of these symptoms, please tell your doctor promptly. Low levels of magnesium can also lead to a reduction in potassium or calcium levels in the blood. Your doctor may decide to perform regular blood tests to monitor your levels of magnesium.

-

Very rarely Lansoprazole may cause a reduction in the number of

white blood cells (agranulocytosis) and your resistance to infection may be decreased or coexisting abnormal reductions in the number of red and white blood cells, as well as platelets (pancytopenia). If you experience an infection with symptoms such as fever and serious deterioration of your general condition, or fever with local infection symptoms such as sore throat/pharynx/mouth or urinary problems, or experience tiredness, pale skin with unexplained bruising or bleeding for longer than normal, you should see your doctor immediately. A blood test will be taken to check possible reduction of blood cells.

-

Rarely Lansoprazole may cause inflammation of the pancreas

(pancreatitis) and its symptoms include sudden intense pains in the middle of the upper abdomen that may radiate to the back, which may lead to nausea and vomiting.
