1. What Omeprazole is and what it is used for

Omeprazole contains the active substance omeprazole. It belongs to a group of medicines called ‘proton pump inhibitors’. They work by reducing the amount of acid that your stomach produces.

Omeprazole is used to treat the following conditions:

In adults:

  • ‘gastro-oesophageal reflux disease’ (GORD). 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 upper part of the intestine (duodenal ulcer) or stomach (gastric ulcer)
  • ulcers which 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
  • ulcers caused by medicines called NSAIDs (Non-Steroidal Anti-Inflammatory Drugs). Omeprazole can also be used to stop ulcers from forming if you are taking NSAIDs.
  • too much acid in the stomach caused by a growth in the pancreas (Zollinger-Ellison syndrome).

In children:

Children over 1 year of age and ≥ 10 kg

  • ‘gastro-esophageal reflux disease’ (GORD). 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. In children, the symptoms of the condition can include the return of stomach contents into the mouth (regurgitation), being sick (vomiting) and poor weight gain.

Children and adolescents aged over 4 years

  • ulcers which are infected with bacteria called ‘Helicobacter pylori’. If your child has 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 Omeprazole

Do not take Omeprazole:

  • if you are allergic to omeprazole or any of the other ingredients of this medicine (listed in section 6)
  • if you are allergic to medicines containing other proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole)
  • if you are taking a medicine containing nelfinavir (used for HIV infection).

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

Warnings and precautions

Talk to your doctor or pharmacist before taking Omeprazole.

Omeprazole may hide the symptoms of other diseases. Therefore, if any of the following happen to you before you start taking Omeprazole 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)
  • you experience severe or persistent diarrhoea, as omeprazole has been associated with a small increase in infectious diarrhoea
  • you have severe liver problems
  • if you have ever had a skin reaction after treatment with a medicine similar to Omeprazole that reduces stomach acid
  • you are due to have a specific blood test (Chromogranin A).

If you take Omeprazole 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.

Taking a proton pump inhibitor like Omeprazole, 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).

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

Children

Some children with chronic illnesses may require long-term treatment although it is not recommended.

Do not give this medicine to children under 1 year of age or < 10 kg.

Other medicines and Omeprazole

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 Omeprazole can affect the way some medicines work and some medicines can have an effect on Omeprazole.

Do not take Omeprazole 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:

  • ketoconazole, itraconazole, posaconazole, or voriconazole (used to treat infections caused by a fungus)
  • digoxin (used to treat heart problems)
  • 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 Omeprazole
  • medicines that are used to thin your blood, such as warfarin or other vitamin K blockers. Your doctor may need to monitor you when you start or stop taking Omeprazole
  • rifampicin (used to treat tuberculosis)
  • atazanavir (used to treat HIV infection)
  • tacrolimus (in cases of organ transplantation)
  • St John’s wort (Hypericum perforatum) (used to treat mild depression)
  • cilostazol (used to treat intermittent claudication)
  • saquinavir (used to treat HIV infection)
  • clopidogrel (used to prevent blood clots (thrombi)
  • erlotinib (used to treat cancer)
  • 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 Omeprazole treatment.

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

3. How to take Omeprazole

Use in children and adolescents

To treat symptoms of GORD such as heartburn and acid regurgitation:

  • Children over 1 year of age and with a body weight of more than 10 kg may take Omeprazole. The dose for children is based on the child’s weight and the doctor will decide the correct dose.

Taking this medicine

  • It is recommended that you take your capsules in the morning.
  • You can take your capsules with food or on an empty stomach.
  • Swallow your capsules whole with half a glass of water. Do not chew or crush the capsules. This is because the capsules 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 or your child have trouble swallowing the capsules

  • If you or your child have trouble swallowing the capsules:
    • open the capsules and swallow the contents directly with half a glass of water or put the contents into a glass of still (non-fizzy) water, any acidic fruit juice (e.g. apple, orange or pineapple) or apple sauce
    • always stir the mixture just before drinking it (the mixture will not be clear). Then drink the mixture straight away or within 30 minutes
    • 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. Do not use milk or carbonated water. The solid pieces contain the medicine - do not chew or crush them.

If you take more Omeprazole than you should

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

If you forget to take Omeprazole

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 to make up for a forgotten dose.

If you stop taking Omeprazole

Do not stop taking Omeprazole without first talking to your doctor or pharmacist.

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

4. Possible side effects

  • reddening of the skin with blisters or peeling. There may also be severe blisters and bleeding in the lips, eyes, mouth, nose and genitals. This could be ‘Stevens-Johnson syndrome’ or ‘toxic epidermal necrolysis’
  • yellow skin, dark urine and tiredness which can be symptoms of liver problems

Other side effects include:

Common side effects (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)

  • allergic reactions, sometimes very severe, including swelling of the lips, tongue and throat, fever, wheezing
  • 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)
  • dry mouth
  • 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)
  • severe kidney problems (interstitial nephritis)
  • increased sweating

Very rare side effects (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)
  • muscle weakness
  • enlarged breasts in men

Not known (frequency cannot be estimated from available data)

  • inflammation in the gut (leading to diarrhoea)
  • if you are on Omeprazole 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.
  • rash, possibly with pain in the joints

Omeprazole 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 medicine at this time.
