Xanax vs. Hydroxyzine
See how Xanax and Hydroxyzine compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Xanax works within minutes for panic attacks but carries real risks of dependence, tolerance, and dangerous withdrawal if stopped suddenly.
Hydroxyzine is not a controlled substance and does not cause physical dependence, but it works more slowly and is not FDA-approved for panic disorder.
Both drugs commonly cause drowsiness, so driving or operating machinery is discouraged until you know how each medication affects you.
Xanax vs. Hydroxyzine Drug Summary
Xanax
Xanax (alprazolam) is a benzodiazepine that is FDA-approved for generalized anxiety disorder and panic disorder. It works within 15 to 45 minutes by boosting GABA activity in the brain and is typically taken two to four times a day as a tablet.
Hydroxyzine
Hydroxyzine is an antihistamine that is FDA-approved for short-term anxiety and tension, plus allergic itching and pre-surgery sedation. It works within 15 to 30 minutes by blocking histamine receptors and is usually taken three to four times a day as a tablet or capsule.

Xanax vs. Hydroxyzine 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 use, since its safety beyond a few months of daily treatment has not been established.
Generalized anxiety disorder (GAD)
Panic disorder, with or without agoraphobia
Short-term relief of anxiety symptoms
Not approved for long-term daily use beyond a few months
Hydroxyzine
Hydroxyzine is FDA-approved for anxiety and tension linked to psychoneurosis, itching from allergic skin conditions, and sedation before and after anesthesia. Doctors sometimes prescribe it off-label for panic attacks or insomnia, though it is not approved for those uses.
Anxiety and tension (psychoneurosis)
Itching from allergic skin conditions
Sedation before and after anesthesia
Off-label: panic disorder, insomnia (not FDA-approved)
Xanax vs. Hydroxyzine Pros and Cons
Xanax
Xanax controls panic symptoms quickly and has decades of trial data supporting its use, but it is a Schedule IV controlled substance with real risks of dependence and withdrawal. Pharmacies often limit refills and require extra monitoring because of its abuse potential.
Pros
Works within 15 to 45 minutes for acute panic and anxiety
Decades of clinical trial data support its use in panic disorder
Available in extended-release form for once-daily dosing
Cons
Schedule IV controlled substance with real abuse and dependence risk
Abrupt discontinuation can cause seizures and severe withdrawal
Black-box warning for dangerous interactions with opioids and alcohol
Pharmacies may limit quantity and refills due to controlled-substance rules
Hydroxyzine
Hydroxyzine is not habit-forming and can be used more flexibly since it is not a controlled substance, though it is not proven to work as well for panic attacks. It also carries anticholinergic side effects and a QT-prolongation warning that Xanax does not share.
Pros
Not a controlled substance, so no risk of physical dependence
Can be used for longer stretches without building tolerance
Also treats allergic itching, useful for overlapping symptoms
Cons
Not FDA-approved or proven effective for panic disorder
More anticholinergic effects like dry mouth and blurred vision
Carries a QT-prolongation warning requiring caution with heart conditions
Slower onset makes it less useful for sudden panic attacks
