Nexium (esomeprazole) (esomeprazole) — Uses, Dosage, Side Effects & Safety

Drug class: Proton Pump Inhibitor (PPI)

Overview

Nexium (esomeprazole) is a medication used to treat conditions caused by excess stomach acid, such as gastroesophageal reflux disease (GERD), erosive esophagitis, Zollinger-Ellison syndrome, and to help heal and prevent stomach ulcers. It is also used in combination with antibiotics to treat Helicobacter pylori infections. Esomeprazole works by reducing the amount of acid your stomach produces. It does this by blocking the proton pumps in the stomach lining, which are responsible for acid secretion. This helps relieve symptoms like heartburn, difficulty swallowing, and persistent cough, and allows the esophagus and stomach lining to heal. Key points for patients: Take Nexium exactly as prescribed, usually before meals. Do not crush or chew the capsules. Inform your doctor of all other medications you are taking, as Nexium can interact with several drugs. Long-term use may require monitoring for certain side effects.
