Summary
Omeprazole is used to treat acid reflux, which is a condition where stomach acid flows back into the esophagus, stomach ulcers, which are sores in the stomach lining, and gastroesophageal reflux disease (GERD), which is a chronic form of acid reflux.
Omeprazole works by blocking the proton pump in the stomach lining, which reduces the production of stomach acid. This helps heal the esophagus and stomach lining, providing relief from symptoms like heartburn and stomach pain.
The usual starting dose of Omeprazole for adults is 20 mg taken once daily before a meal. The capsule should be swallowed whole, not crushed or chewed. Dosage may be adjusted by a doctor based on individual needs.
Common side effects of Omeprazole include headache, which is pain in the head, nausea, which is a feeling of sickness with an inclination to vomit, and diarrhea, which is frequent loose or liquid bowel movements.
Omeprazole should not be taken by individuals allergic to it or its ingredients. Long-term use can lead to low magnesium levels, which may cause muscle spasms or irregular heartbeat. It may also increase the risk of bone fractures.
