Alprazolam 0.5 mg is a prescription medication in the benzodiazepine class that is clinically indicated for the short-term management of anxiety disorders and panic disorder when evaluated and prescribed by a licensed healthcare professional. It works by enhancing the activity of gamma-aminobutyric acid (GABA) in the brain, which helps calm excessive nervous system activity and can reduce symptoms such as intense worry, restlessness, rapid heartbeat, and acute panic episodes.
