What Is Xanax?

Xanax, also known as alprazolam, is a medication commonly used to treat anxiety and panic disorders. It is available by prescription only, and patients who use it have their health closely monitored to reduce the risk of developing dependence. Xanax is frequently prescribed as an extended-release tablet, and it is also available in immediate-release tablets, oral solutions, and injections. Patients who take Xanax orally usually start with a dose between 0.25 to 0.5 milligrams, and tablets are taken up to three times per day. Before prescribing Xanax, doctors will ask the patient about any history of narrow-angle glaucoma, kidney disease, asthma, epilepsy, or depression. Xanax may not be safe for patients with these conditions.
