Omeprazole capsules contain 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:

  • 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).
