Prilosec (omeprazole) belongs to a group of drugs called proton pump inhibitors. Omeprazole decreases the amount of acid produced in the stomach.
rnPrilosec is used to treat symptoms of gastroesophageal reflux disease (GERD) and other conditions caused by excess stomach acid. It is also used to promote healing of erosive esophagitis (damage to your esophagus caused by stomach acid).
rnPrilosec may also be given together with antibiotics to treat gastric ulcer caused by infection with helicobacter pylori (H. pylori).
rnPrilosec is not for immediate relief of heartburn symptoms.
