Hydroxyzine is an antihistamine used in dogs to treat atopic dermatitis, used in cats with symmetrical alopecia of an allergic origin, miliary dermatitis and eosinophilic granuloma complex. It is helpful for relief of itching and usually works within 20-45 minutes. Hydorxyzine can be combined with other medications such as corticosteroid in cases of severe itching.

Dosages for Hydroxyzine vary depending on the type and size of the animal so always be sure to administer the proper dosage. See directions below and your package instructions for details; always follow your veterinarian's prescribed dosage if it differs from the standard dosage recommendations.
