Famotidine is used to treat stomach ulcers (gastric and duodenal), erosive esophagitis (heartburn or acid indigestion), and gastroesophageal reflux disease (GERD). GERD is a condition where the acid in the stomach washes back up into the esophagus. It is also used to treat certain conditions where there is too much acid in the stomach (eg, Zollinger-Ellison syndrome, multiple endocrine neoplasia).
Famotidine belongs to the group of medicines known as histamine H2-receptor antagonists or H2-blockers. It works by decreasing the amount of acid produced by the stomach.
