Alprazolam (Xanax): Uses, Dosage, Side Effects, Warnings, and Precautions

What Is Alprazolam (Xanax)?

Alprazolam is a prescription medication used to treat anxiety disorders, panic disorder, and anxiety associated with depression. It belongs to a class of medicines known as benzodiazepines, which work by enhancing the activity of gamma-aminobutyric acid (GABA), a natural chemical in the brain that helps calm the nervous system.

Alprazolam is commonly sold under the brand name Xanax in the United States and several other countries. Because it has the potential for misuse, dependence, and withdrawal, it is classified as a controlled substance in many countries and should only be used exactly as prescribed.

How Alprazolam Works

Alprazolam enhances the effects of GABA (gamma-aminobutyric acid), a neurotransmitter that reduces excessive brain activity. This produces a calming effect, helping relieve anxiety, reduce panic symptoms, promote relaxation, and in some cases improve sleep.

The medicine typically begins working within 30 to 60 minutes, with peak effects occurring in about 1 to 2 hours.

---

General Dosage

The appropriate dose depends on:

• Age
• Medical condition
• Severity of symptoms
• Response to treatment

Treatment usually starts with a low dose, which may be adjusted gradually by the healthcare provider.

Do not increase your dose or take alprazolam more frequently than prescribed.
