Omeprazole

Omeprazole is a medicine that reduces the production of stomach acid. Omeprazole belongs to the so-called proton pump inhibitors. These block the production of stomach acid by irreversibly inhibiting the proton pump.

What is omeprazole used for?

Omeprazole is mainly used for stomach complaints, stomach ulcers, and duodenal ulcers. It can also be used alongside other medicines that can damage the stomach. Examples include prednisone or other anti-inflammatories, often referred to as NSAIDs (Nonsteroidal Anti-Inflammatory Drugs). A specialist or family doctor can prescribe omeprazole.

Symptoms for which people often use the medicine include nausea, heartburn, or reflux of stomach acid into the esophagus.

What are possible side effects of omeprazole?

In practice, side effects are uncommon. If they do occur, they include gastrointestinal complaints such as diarrhea, constipation, nausea, and vomiting. Headache is also a rarely occurring side effect. In practice, these side effects occur in 1-10 out of 100 people. Very rarely, occurring in fewer than 1 out of 100 people, side effects such as dizziness, hair loss, double vision, and rash are seen.

Research has also shown that proton pump inhibitors reduce the absorption of vitamin B12 and can cause a vitamin deficiency over the long term. The risk of chronic kidney disease is relatively higher in people who use proton pump inhibitors for a long time.
