Omeprazole reduces the amount of acid produced in your stomach. It belongs to a group of medicines known as proton pump inhibitors (PPIs).
- Omeprazole is used to treat conditions associated with high levels of stomach acid, such as indigestion, reflux and ulcers. It can prevent ulcers from forming or help the healing process where damage has already occurred.
- Omeprazole can be used to prevent ulcers caused by medicines such as non-steroidal anti-inflammatory drugs (NSAIDs). Examples of NSAIDs are diclofenac, ibuprofen, and naproxen.
- It can also be given together with certain antibiotics to get rid of Helicobacter pylori, a bacteria found in your stomach that can cause ulcers.
