How does this medication work? What will it do for me?
Famotidine belongs to a class of medications called H2antagonists. It is used to treat stomach and duodenal (intestinal) ulcers, gastroesophageal reflux disease (GERD), and conditions where too much stomach acid is secreted, such as Zollinger-Ellison syndrome. It works by reducing the amount of acid secreted by the stomach.
The over-the-counter form of famotidine is used to treat conditions where a reduction of stomach acid is needed, such as acid indigestion, heartburn, or sour or upset stomach. It can also be used to prevent these symptoms when they are associated with eating food or drinking beverages, including nighttime symptoms.
