H2-receptor antagonist
Is Famotidine vegetarian or vegan-friendly?
Vegetarian and vegan patients sometimes ask whether their medication contains animal-derived ingredients. The active substance Famotidine in Famotidine is almost always synthetically produced; the question typically concerns excipients in the tablet or capsule shell at 10mg, 20mg, 40mg.
Animal-derived excipients in Famotidine
Common animal-derived excipients in pharmaceuticals include gelatin (in capsule shells, derived from porcine or bovine sources), lactose (dairy-derived), and certain magnesium stearate sources. The prescribing information and patient leaflet for Famotidine list excipients; whether they are animal-derived is sometimes specified, sometimes left ambiguous. Famotidine reversibly and competitively blocks histamine H2 receptors on gastric parietal cells, reducing both basal and stimulated gastric acid secretion.
Practical guidance
According to general pharmacy practice, vegetarians and vegans concerned about Famotidine excipients should ask the pharmacist or manufacturer directly. Many medications have authorised generic versions with different excipient profiles — switching to a generic of Famotidine with vegetable-derived excipients is sometimes possible at 10mg, 20mg, 40mg. For strict requirements (e.g. religious or strong ethical), specialist pharmacy consultation gives definitive answers.

For strict vegan requirements, confirm with the manufacturer or pharmacist for the specific Famotidine product.
