Question: what is the difference between hydroxyzine and vistaril?
Answer: Vistaril (hydroxyzine pamoate) is used for anxiety and nausea where as Atarax is used for allergies and itching. Both Atarax(hydroxyzine hcl) and Vistaril(pam) do the same thing, but it depends on how your body reacts to it; one may work better than the other.
