Losec (omeprazole) (omeprazole) — Uses, Dosage, Side Effects & Safety

Drug class: Proton Pump Inhibitor (PPI)

Overview

Losec (omeprazole) is a medication used to treat conditions caused by excess stomach acid, such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome. It is also prescribed for the prevention and treatment of ulcers caused by nonsteroidal anti-inflammatory drugs (NSAIDs) and for Helicobacter pylori eradication in combination therapy. Omeprazole works by blocking the proton pumps in the stomach lining, which are responsible for producing stomach acid. By reducing acid production, it helps relieve symptoms like heartburn, difficulty swallowing, and persistent cough, and allows the esophagus and stomach lining to heal. Key points for patients: Losec is usually taken once daily, preferably before a meal. It may take a few days to feel the full benefit. Do not stop taking Losec suddenly without consulting your doctor, especially if you have been on it for a long time.
