Hydroxyzine (Atarax, (Vistaril) is an antihistamine (as are many antidepressants, BTW) mostly prescribed for allergies, nasal congestion, motion nausea, etc. However, it does have anti anxiety properties, and can be all that some need to cage the anxiety beast. It is being prescribed more for anxiety by doctors as an alternative to benzodiazepines. Dentists have used it for years to ease anxiety in dental phobic patients.
Hope it works for you
