Your vet may use an antihistamine as a treatment for hypersensitivity and allergic disorders. The particular antihistamine selected by your vet depends on their preference, the specifics of the condition being treated, and the horse. Antihistamines are given orally and by injection.xtra-label use of human antihistamines is also common in equine practice. Examples of these medications include hydroxyzine, diphenhydramine (Benadryl) and cetirizine, among many others. Cetirizine was shown NOT to be effective for treatment of Sweet Itch in horses.
