About Omeprazole

What is omeprazole?

Omeprazole is a prescription-only medicine known as a proton pump inhibitor (PPI), which is used to treat acid reflux and indigestion. Omeprazole comes in tablet or liquid form.

How does omeprazole work?

Omeprazole is a kind of medicine known as a proton pump inhibitor (PPI). Proton pumps are found in the lining of the stomach and make acid which digests food. Omeprazole prevents these proton pumps from working properly, which reduces the amount of acid the stomach makes. This reduces the risk of acid reflux and indigestion.

How long does it take for omeprazole to work?

Most people who get regular acid reflux start to feel better within 2-3 days of first taking omeprazole. This will differ from person to person, and it may take up to 4 weeks before all your symptoms disappear. If you take omeprazole for two weeks and notice no difference to your symptoms, book an appointment to see your GP. They may suggest an alternative medicine to take.
