Overview
Hydroxyzine is a first-generation antihistamine that has significant anti-anxiety properties. Unlike benzodiazepines, it's not a controlled substance and carries no risk of addiction. At Next Step Psychiatry, we often prescribe hydroxyzine for situational anxiety, as an adjunct to other anxiety treatments, or for anxiety-related sleep difficulties. It can be used "as needed" or on a regular schedule.
How Vistaril / Atarax Works
Hydroxyzine works by blocking histamine H1 receptors in the brain, which produces calming and sedating effects. It also has some effects on serotonin and acetylcholine receptors. The anti-anxiety effect is relatively rapid, making it useful for acute anxiety situations.

Frequently Asked Questions
Is hydroxyzine addictive?
No, hydroxyzine is not addictive or habit-forming. It's not a controlled substance. This is one reason it's often preferred over benzodiazepines for anxiety, especially for long-term use or in patients with addiction history.
Can I take hydroxyzine every day?
Yes, hydroxyzine can be taken on a regular schedule for ongoing anxiety. However, drowsiness may persist. Many people use it "as needed" for situational anxiety or at bedtime for sleep-related anxiety.
How is hydroxyzine different from Benadryl?
Both are antihistamines, but hydroxyzine has stronger anti-anxiety effects and is specifically used for anxiety. Hydroxyzine also causes less cognitive impairment than diphenhydramine (Benadryl) at equivalent sedating doses.
