Prilosec, or Omeprazole, is used to treat conditions in which there is too much acid in the stomach, like duodenal and gastric ulcers and gastroesophageal reflux disease (GERD), a condition in which the acid in the stomach washes back up into the esophagus. Prilosec is sometimes used in combination with antibiotics to treat ulcers associated with infection caused by the H. pylori bacteria, and is also used to treat Zollinger-Ellison disease, a condition in which the stomach produces too much acid.
Prilosec is also used to treat dyspepsia, a condition that causes sour stomach, belching, heartburn, or indigestion, and is used to prevent upper gastrointestinal tract bleeding in seriously ill patients. It works by decreasing the amount of acid produced by the stomach
