Hydroxyzine
"Unfortunately I had started seeing a new Dr that didn't believe in using any benzo's. She took me off my 9  yrs of benzo therapy & prescribed Vistaril. Started with 25-50 mg, 4-6 times a day. It wasn't long before she raised me to, literally, up to 150 MG's, titrated over 40-45 mins! That was ridiculous, it also did nothing. 
Now I use my Vistaril for my allergies & my current Dr has me alternating 3 x's each, approx 3-4 hrs apart - Xanax 2 mg with Vistaril 25-50 mg to "extend" the Xanax.
IMO, this medication stinks!! Doesn't even assist me to sleep."
