Famotidine is a medication that belongs to a class of drugs known as H2 blockers. It works by reducing the amount of stomach acid produced by the cells in the stomach lining. This helps alleviate symptoms associated with conditions like gastroesophageal reflux disease (GERD) and peptic ulcers. Typically available in both prescription and over-the-counter forms, Famotidine is used to treat heartburn, indigestion, and other related issues. It is generally considered safe for short-term use, but like all medications, it may have side effects and should be taken as directed by a healthcare professional.
