Vistaril is not necessarily the drug of choice but may be applicable in certain situations. It is not likely to cause dependence. 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.
Edit: I just realized that I mixed up Vistaril and Flexeril, a muscle relaxant, in the above explanation. I thought Flexeril was the Canadian brand name of Vistaril.
