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

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 are coated which stop the medicine from being broken down by the acid in your stomach. It is important not to damage the capsules.

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

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

  • Sudden wheezing, swelling of your lips, tongue and throat or body, rash, fainting or difficulties in swallowing (severe allergic reaction).
  • 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.

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.
