Xanax is the brand name for alprazolam, a benzodiazepine medication approved to treat generalized anxiety disorder and panic disorder. It works by boosting a calming chemical in your brain known as gamma-aminobutyric acid (GABA), which slows down brain activity and makes you feel calmer and more relaxed.

Before Taking This Medicine

You should not take Xanax if:

• you also take antifungal medicine such as itraconazole or ketoconazole; or
• you have a history of allergic reaction to any benzodiazepine (alprazolam, lorazepam, diazepam, Ativan, Valium, Versed, Klonopin, and others).

To make sure Xanax is safe for you, tell your doctor if you have ever had:

• breathing problems;
• drug or alcohol addiction;
• depression, mood problems, or suicidal thoughts or behavior; or

• kidney or liver disease.
