Alprazolam, a tranquilizer that belongs to the benzodiazepine pharmacological class, is marketed under the name Xanax. These depressive medications are frequently used to treat seizures, sleeplessness, and anxiety disorders. Three brand names are often used to refer to this specific benzodiazepine: Xanax, Niravam, and Xanax RX. It is against the law to buy or use Xanax without a prescription from a doctor because it is a controlled substance. This medication, which is used orally once to three times a day, is most typically available as an oval white pill, although it is also available as yellow, red, or blue Xanax "bars."
