Usage of Famotidine
Famotidine is a Histamine-2 blocker that works by decreasing the amount of acid the stomach produces.
Famotidine is used to treat and prevent ulcers in the stomach and intestines. It also treats conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome.
Famotidine also treats gastroesophageal reflux disease (GERD) and other conditions in which acid backs up from the stomach into the esophagus, causing heartburn.
The Zantac 360 brand of this medicine does not contain Ranitidine, a medicine that was withdrawn from market in the United States.
