Hydroxyz, or hydroxyzine, is the generic form of Vistaril and Atarax. It is a strong antihistamine, think industrial strength benadryl. It is prescribed for the same uses that you would take the over the counter Benadryl for. Like runny nose, allergies, or itching. Like benadryl to also has sedative effect, but stronger. So, is also prescribed for insomnia and anxiety.
