What Is Famotidine 20mg?
Famotidine is a histamine-2 (H2) blocker that reduces the amount of acid your stomach produces. It is the generic version of the brand-name drug Pepcid and comes as an oral tablet. Prescription-strength famotidine is used for gastroesophageal reflux disease (GERD), ulcers of the stomach and small intestine, and conditions where the stomach makes too much acid. Lower doses of famotidine can be bought over the counter for occasional heartburn, but prescription famotidine is intended for provider-directed treatment of diagnosed conditions.
