About this active substance

Omeprazole is a medication used to treat conditions associated with excess stomach acid, such as gastroesophageal reflux disease (GERD), gastric and duodenal ulcers, erosive esophagitis, and Zollinger-Ellison syndrome. It belongs to the class of proton pump inhibitors (PPIs) and works by reducing stomach acid production, thereby protecting the lining of the stomach and esophagus.

Omeprazole is taken orally, usually once daily before a meal, and the duration of treatment varies depending on the condition. It is effective in relieving symptoms such as heartburn, acid regurgitation, and epigastric pain.

Common side effects include headache, nausea, diarrhea, constipation, or abdominal pain. Long-term use may increase the risk of gastrointestinal infections, vitamin B12 deficiency, or osteoporosis. It is important to use omeprazole as directed by a healthcare provider and to avoid abrupt discontinuation of the treatment.
