In veterinary medicine, diphenhydramine is widely prescribed and primarily used for its antihistamine effects. Veterinarians also rely on diphenhydramine for its sedative effects for conditions such as motion sickness and antiemetic properties. Vetadryl is a flavored diphenhydramine HCl tablet for cats and dogs.

Each chicken liver flavored tablet tested 7x more palatable than over-the-counter diphenhydramine and is scored for flexible dosing for even the smallest patient. Vetadryl can aid in the management of allergies, insect bites, motion sickness, travel anxiety, and other conditions.
