Patient leaflet - Esomeprazole Sandoz 40 mg gastro-resistant tablets

what it is used for

Esomeprazole Tablets contain a medicine called esomeprazole. This belongs to a group of medicines called ‘proton pump inhibitors’. They work by reducing the amount of acid that your stomach produces.

Esomeprazole Tablets are used to treat the following conditions:

Adults

  • ‘Gastroesophageal reflux disease’ (GERD). This is where acid from the stomach escapes into the gullet (the tube which connects your throat to your stomach) causing pain, inflammation and heartburn.
  • Ulcers in the stomach or upper part of the gut (intestine) that are infected with bacteria called ‘Helicobacter pylori’. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
  • Stomach ulcers caused by medicines called NSAIDs (Non-Steroidal Anti-Inflammatory Drugs).
  • To stop stomach ulcers from forming if you are taking NSAIDs.
  • Too much acid in the stomach caused by a growth in the pancreas (Zollinger-Ellison syndrome).
  • Prolonged treatment after prevention of rebleeding of peptic ulcers with intravenous esomeprazole.

Adolescents aged 12 years and above

  • ‘Gastroesophageal reflux disease’ (GERD). This is where acid from the stomach escapes into the gullet (the tube which connects your throat to your stomach) causing pain, inflammation and heartburn.
  • Ulcers in the stomach or upper part of the gut (intestine) that are infected with bacteria called ‘Helicobacter pylori’. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

2 What you need to know before

you take Esomeprazole

Do not take Esomeprazole

  • If you are allergic to esomeprazole or any of the other ingredients of this medicine (listed in section 6).
  • If you are allergic to other proton pump inhibitor medicines (e.g. pantoprazole, lansoprazole, rabeprazole, omeprazole).
  • If you are taking a medicine containing nelfinavir (used to treat HIV infection).
  • If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Esomeprazole or other related medicines

Do not take Esomeprazole Tablets if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Esomeprazole.

Warnings and precautions

Talk to your doctor or pharmacist before taking Esomeprazole :

  • If you have severe liver problems.
  • If you have severe kidney problems.
  • If you have ever had a skin reaction after treatment with a medicine similar to esomeprazole that reduces stomach acid. Serious skin reactions including Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported in association with medicinal treatment. Stop using this medicine and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.
  • If you are due to have a specific blood test (Chromogranin A).

Esomeprazole may hide the symptoms of other diseases. Therefore, if any of the following happen to you before you start taking Esomeprazole or while you are taking it, talk to your doctor straight away:

  • You lose a lot of weight for no reason and have problems swallowing.
  • You get stomach pain or indigestion.
  • You begin to vomit food or blood.
  • You pass black stools (blood-stained faeces).

If you have been prescribed Esomeprazole “on demand” you should contact your doctor if your symptoms continue or change in character.

Taking a proton pump inhibitor like Esomeprazole, 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 or if you are taking corticosteroids (which can increase the risk of osteoporosis).

Rash and skin symptoms

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 Esomeprazole. Remember to also mention any other ill-effects like pain in your joints.

Serious skin rashes have occurred in patients taking esomeprazole (see also section 4). The rash can involve ulcers of the mouth, throat, nose, genitals and conjunctivitis (red and swollen eyes). These serious skin rashes often come after flu-like symptoms such as fever, headache, body ache. The rash may cover large parts of the body with blistering and peeling of the skin.

If at any time during the treatment (even after several weeks) you develop a rash or any of these skin symptoms, stop taking this medicine and contact your doctor immediately.

Other medicines and Esomeprazole

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This includes medicines that you buy without a prescription. This is because Esomeprazole can affect the way some medicines work, and some medicines can have an effect on Esomeprazole .

Do not take Esomeprazole if you are taking a medicine containing nelfinavir (used to treat HIV infection).

Tell your doctor or pharmacist if you are taking any of the following medicines:

  • Atazanavir (used to treat HIV infection).
  • Clopidogrel (used to prevent blood clots).
  • Ketoconazole, itraconazole or

    voriconazole (used to treat infections caused by a fungus).

  • Erlotinib (used to treat cancer).
  • Citalopram, imipramine or clomipramine (used to treat depression).
  • Diazepam (used to treat anxiety, relax muscles or in epilepsy).
  • Phenytoin (used in epilepsy). If you are taking phenytoin, your doctor will need to monitor you when you start or stop taking Esomeprazole.
  • Medicines that are used to thin your blood, such as warfarin. Your doctor may need to monitor you when you start or stop taking Esomeprazole.

    • Cilostazol (used to treat intermittent claudication – a pain in your legs when you walk which is caused by an insufficient blood supply).
    • Cisapride (used for indigestion and heartburn).
    • Digoxin (used for heart problems).
    • Methotrexate (a chemotherapy medicine used in high doses to treat cancer) – if you are taking a high dose of methotrexate, your doctor may temporarily stop your Esomeprazole treatment.
    • Tacrolimus (organ transplantation).
    • Rifampicin (used for treatment of tuberculosis).
    • St. John’s wort (Hypericum perforatum) (used to treat depression).

If your doctor has prescribed the antibiotics amoxicillin and clarithromycin as well as Esomeprazole to treat ulcers caused by Helicobacter pylori infection, it is very important that you tell your doctor about any other medicines you are taking. 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

Esomeprazole with food and drink

You can take your tablets with food or on an empty stomach.

Pregnancy, breast-feeding and fertility

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. Your doctor will decide whether you can take Esomeprazole during this time. It is not known if Esomeprazole passes into breast milk. Therefore, you should not take Esomeprazole if you are breastfeeding.

Driving and using machines

Esomeprazole is not likely to affect you being able to drive or use any tools or machines. However, side effects such as dizziness and blurred vision may uncommonly or rarely occur (see section 4). If affected, you should not drive or use machines.

Esomeprazole contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium free’.

Esomeprazole contains sucrose and lactose

If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

To treat ulcers caused by Helicobacter pylori infection and to stop them coming back:

  • The recommended dose is one Esomeprazole 20 mg gastro-resistant tablet twice a day for one week.
  • Your doctor will also tell you to take antibiotics for example amoxicillin and clarithromycin.

Use in children under the age of 12 years

Esomeprazole is not recommended for children less than 12 years old.

Elderly

Dose adjustment is not required on the elderly.

Taking this medicine

  • You can take your tablets at any time of the day.
  • You can take your tablets with food or on an empty stomach.
  • Swallow your tablets whole with a drink of water. Do not chew or crush the tablets. This is because the tablets contain coated pellets which stop the medicine from being broken down by the acid in your stomach. It is important not to damage the pellets.

What to do if you have trouble swallowing the tablets

  • If you have trouble swallowing the tablets:

    • Put them into a glass of still (non-fizzy)

      water. Do not use any other liquids.

    • Stir until the tablets break up (the

      mixture will not be clear). Then drink the mixture straight away or within 30 minutes. Always stir the mixture just before drinking it.

    • To make sure that you have drunk all

      of the medicine, rinse the glass very well with half a glass of water and drink it. The solid pieces contain the medicine - do not chew or crush them.

  • If you cannot swallow at all, the tablet can be mixed with some water and put into a syringe. It can then be given to you through a tube directly into your stomach (‘gastric tube’).

If you take more Esomeprazole than you should

If you take more Esomeprazole than prescribed by your doctor, talk to your doctor or pharmacist straight away.

If you forget to take Esomeprazole

If you forget to take a dose, take it as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose.

Do not take a double dose (two doses at the same time) to make up for a forgotten dose.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

4 Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

If you notice any of the following serious side effects, stop taking Esomeprazole and contact a doctor immediately:

  • Yellow skin, dark urine and tiredness which can be symptoms of liver problems. These effects are rare, and may affect up to 1 in 1,000 people.
  • Sudden wheezing, swelling of your lips, tongue and throat or body, rash, fainting or difficulties in swallowing (severe allergic reaction). These effects are rare and may affect up to 1 in 1,000 people.
  • Sudden onset of a severe rash or reddening of the skin with blisters or peeling may occur even after several weeks of treatment. There may also be severe blisters and bleeding in the lips, eyes, mouth, nose and genitals. The skin rashes may develop into serious widespread skin damage (peeling of the epidermis and superficial mucous membranes) with life threatening consequences. This could be ‘erythema multiforme’, ‘Stevens-Johnson syndrome’, ‘toxic epidermal necrolysis’ or ‘drug reaction with eosinophilia and systemic symptoms’(DRESS). These effects are very rare, and might affect up to 1 in 10,000 people.
  • Widespread rash, high body temperature and enlarged lymph nodes (DRESS syndrome or drug hypersensitivity syndrome), seen very rarely.

Other side effects include:

Common (may affect up to 1 in 10 people)

  • Headache.
  • Effects on your stomach or gut: diarrhoea, stomach pain, constipation, wind (flatulence).
  • Feeling sick (nausea) or being sick (vomiting).
  • Benign polyps in the stomach.

Uncommon (may affect up to 1 in 100 people)

  • Swelling of the feet and ankles.
  • Disturbed sleep (insomnia).
  • Dizziness, tingling feelings such as “pins and needles”, feeling sleepy.
  • Spinning feeling (vertigo).
  • Dry mouth.
  • Changes in blood tests that check how the liver is working.
  • Skin rash, lumpy rash (hives) and itchy skin.
  • Fracture of the hip, wrist or spine (if used in high doses and over long duration).

Rare (may affect up to 1 in 1,000 people)

  • Blood problems such as a reduced number of white cells or platelets. This can cause weakness, bruising or make infections more likely.
  • Low levels of sodium in the blood. This may cause weakness, being sick (vomiting) and cramps.
  • Feeling agitated, confused or depressed.
  • Taste changes.
  • Eyesight problems such as blurred vision.
  • Suddenly feeling wheezy or short of breath (bronchospasm).
  • An inflammation of the inside of the mouth.
  • An infection called “thrush” which can affect the gut and is caused by a fungus.
  • Liver problems, including jaundice which can cause yellow skin, dark urine, and tiredness.
  • Hair loss (alopecia).
  • Skin rash on exposure to sunshine.
  • Joint pains (arthralgia) or muscle pains (myalgia).
  • Generally feeling unwell and lacking energy.
  • Increased sweating.

Very rare (may affect up to 1 in 10,000 people)

  • Changes in blood count including agranulocytosis (lack of white blood cells)
  • Aggression.
  • Seeing, feeling or hearing things that are not there (hallucinations).
  • Severe liver problems leading to liver failure and inflammation of the brain.
  • Sudden onset of a severe rash or blistering or peeling skin. This may be associated with a high fever and joint pains (Erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms).
  • Muscle weakness.
  • Severe kidney problems.
  • Enlarged breasts in men.

Not known (frequency cannot be estimated from the available data)

  • If you are on Esomeprazole 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 or 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.
  • Inflammation in the gut (leading to diarrhoea).
  • Rash, possibly with pain in the joints.

Esomeprazole may, in very rare cases affect the white blood cells leading to immune deficiency. If you have an infection with symptoms such as fever with a severely reduced general condition or fever with symptoms of a local infection

such as pain in the neck, throat or mouth or difficulties in urinating, you must consult your doctor as soon as possible so that a lack of white blood cells (agranulocytosis) can be ruled out by a blood test. It is important for you to give information about your medication at this time.
