Fact Checked

Alprazolam is the generic version of Xanax. As a benzodiazepine, alprazolam calms anxiety and panic disorder by slowing down the nervous system. The downside is that its use can lead to dependence and addiction, so healthcare professionals are cautious to use it only for short-term treatment and only when necessary.
