Pharmacology
Famotidine belongs to a class of medicines called H2-receptor antagonists. It works by completely blocking the action of histamine on the H2-receptors found in the acid-producing cells of the stomach lining. Through this action, it reduces acid secretion that would otherwise occur at baseline, overnight, and in response to pentagastrin stimulation. Because famotidine separates only slowly from these H2-receptors once bound, its acid-suppressing effect also wears off gradually rather than stopping abruptly.
Pregnancy & Breastfeeding
Famotidine has been placed in pregnancy category B. There are no adequate, well-controlled studies in pregnant women, so the medicine should be used during pregnancy only when it is clearly needed. Care is also needed when famotidine is given to a woman who is breastfeeding.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
