What is famotidine used for?

Famotidine is used to treat heartburn, acid indigestion, and intestinal and stomach ulcers, according to WebMD. It also prevents the return of intestinal ulcers and is often prescribed to treat throat and stomach problems that result from GERD and erosive esophagitis. It is sold under the brand name Pepcid.

Famotidine is an H2 histamine blocker that reduces the prevalence of acid in the stomach and can alleviate symptoms of stomach pain. It is available over the counter. Those self-medicating with OTC famotidine should not take the medication for more than 14 days without consulting a physician. No more than two tablets should be taken in a 24-hour period, according to WebMD.
