Esomeprazole is in a class of drugs called proton pump inhibitors. It works by decreasing the amount of acid made in your stomach. Esomeprazole is used to treat your esophagus, the area between your throat and stomach that has become irritated, painful, and swollen from too much acid in your stomach. It is used to treat heartburn, acid indigestion, sour stomach, and other conditions in which the stomach makes too much acid. Esomeprazole also is used in combination with antibiotics to treat ulcers.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
