Vistaril - will hydroxyzine hcl help with my allergy to cats?

It may. Hydroxyzine (brand names: Atarax, Vistaril) is an antihistamine used to treat allergic and itchy conditions or as a sedative/tranquilizer. For me it helps with everything that makes me miserable during allergy season, pollen mainly. I’m not allergic to cats however. It keeps my eyes from watering constantly and I seem to breathe much better when I’m taking it during allergy season. We are all different. I would recommend starting with a low dose of 25mg. It may make you sleepy initially (much like Benadryl.) I hope this helps, good luck to you!
