About Diphenhydramine

Histamine is a chemical that is released in the body in response to inflammation or allergy, traveling throughout the body and searching for specific histamine receptors (targets on cells). Once attached to the receptors, histamine will cause swelling, itchiness and other symptoms associated with an allergic reaction. Diphenhydramine, the generic of Benadryl, is an antihistamine that inhibits the action of histamine, particularly its effect on H1 receptors. This drug is not approved for use in animals by the Food and Drug Administration but it is prescribed legally by veterinarians as an extra-label drug.
