About Famotidine
An H2 receptor blocker that replaced ranitidine after its withdrawal. Famotidine or Pepcid treats GERD and stomach ulcers. It is available over the counter. Famotidine gained attention during the COVID 19 pandemic when some researchers suggested it might improve outcomes, though evidence remains inconclusive. The drug is generally safe and well tolerated. After ranitidine withdrawal, famotidine became the primary H2 blocker for acid suppression.
