Good Evening, I am glad to see you started a new thread as this way current members will see your thread and lend you a helping hand.Vistaril is an antihistamine with mild sedating and anxiety-relieving effects. It doesn't work the same as a benzodiazepine (Valium, Ativan ETC), but then it's not addictive either. Some people get a lot of relief from Vistaril and similar meds; some don't. Talk to your doctor about what works for you and what doesn't. There may be other options to explore.
For symptomatic relief of anxiety, Vistaril may be prescribed as noted below:
Vistaril 50-100 mg PO divided q6hr as needed.
You posted you are taking 4 50mg doses which equals 200mg but in what time frame are you using this much of the medication?
I agree with talking to your Dr. about wean off of this med if it is causing you problems similar to withdrawal sx.
Kindly,
Kitt
