Omeprazole belongs to a group of medicines called 'proton pump inhibitors'. They work by reducing the amount of acid that your stomach produces. Omeprazole stop cells in the lining of the stomach from producing too much acid. This can help prevent ulcers from forming or assist the healing process. By decreasing the amount of acid, they can also help to reduce acid reflux related symptoms such as heartburn.
Omeprazole is prescribed to treat the following conditions:
- ‘Gastro-oesophageal reflux disease’ (GORD). This is where acid from the stomach escapes into
the gullet causing pain, inflammation and
heartburn and can lead to problems with swallowing.
- 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
tablets 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).
How to take Omeprazole
- Before starting this treatment, read the patient information leaflet from inside the pack.
- You can take your capsules with food or on an empty stomach.
- Try to take Omeprazole at the same time each day to avoid missing any doses.
- It is recommended that you take your capsules in the morning.
- 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.

20 mg once a day for 4-8 weeks. Your doctor may tell you to take a dose of 40 mg for a further 8

To prevent the duodenal and stomach ulcers from coming back, the usual dose is 10 mg or 20 mg once a day. Your doctor may increase the dose to 40 mg once
