Key Takeaways
Xanax is a Schedule IV benzodiazepine with a boxed warning for abuse and dependence, while Vistaril is an antihistamine with no controlled substance status.
Both drugs can ease anxiety symptoms, but they work through completely different mechanisms and have different side effect profiles.
Xanax is approved specifically for panic disorder and short-term anxiety, while Vistaril's label also covers allergic itching and pre-surgery sedation.
Xanax vs. Vistaril Drug Summary
Xanax
Xanax (alprazolam) is a fast-acting benzodiazepine used to treat generalized anxiety disorder and panic disorder. It works by boosting the calming effect of a brain chemical called GABA. Most people take it two to four times a day as a regular tablet.
Vistaril
Vistaril (hydroxyzine pamoate) is an antihistamine used to relieve anxiety and tension, as well as itching from allergic skin conditions. It is taken as an oral capsule or liquid, usually several times a day. It is also used for sedation before and after general anesthesia.

Xanax vs. Vistaril Indications
Xanax
Xanax is FDA approved for two conditions: generalized anxiety disorder and panic disorder, with or without agoraphobia. It is meant for short-term relief of anxiety symptoms rather than open-ended daily use in most patients.
Acute treatment of generalized anxiety disorder in adults
Panic disorder, with or without agoraphobia
Not approved for depression, insomnia, or itching
Schedule IV controlled substance due to misuse risk
Vistaril
Vistaril is FDA approved for anxiety and tension linked to psychoneurosis, and as an add-on for anxiety tied to a physical illness. It also treats itching from allergic skin conditions and provides sedation before and after general anesthesia.
Anxiety and tension associated with psychoneurosis
Adjunct treatment for anxiety linked to organic illness
Itching from chronic hives, dermatitis and other allergies
Sedation before and after general anesthesia
Xanax vs. Vistaril Pros and Cons
Xanax
Xanax works quickly, often within an hour, which makes it useful for sudden panic attacks. It is a Schedule IV controlled substance with a boxed warning covering abuse, dependence, and dangerous interactions with opioids. As a widely used generic, it's usually easy to find at any pharmacy.
Pros
Fast onset, often within 15-60 minutes, useful for acute panic
FDA-approved specifically for panic disorder, unlike Vistaril
Widely available as a low-cost generic at most pharmacies
No dry-mouth or anticholinergic burden like Vistaril has
Cons
Controlled substance with real risk of dependence and misuse
Carries a boxed warning for abuse and opioid interactions
Not approved for allergic itching or pre-surgery sedation
Needs a gradual taper; stopping abruptly can trigger seizures
Vistaril
Vistaril carries no boxed warning and has little potential for abuse or dependence, since it is not a controlled substance. Its label is broader than Xanax's, covering both anxiety and allergic itching. It generally needs dosing multiple times a day rather than as-needed use.
Pros
Not a controlled substance, so no dependence or misuse risk
No boxed warning, unlike Xanax's abuse and opioid warning
Also FDA approved to treat itching from allergic skin conditions
Can double as sedation before and after anesthesia
Cons
Slower onset, less useful for a sudden panic attack
Usually dosed up to four times daily rather than as-needed
Carries its own warning about QT prolongation
Not approved specifically for panic disorder like Xanax is
