Alprazolam is used for all types of anxiety, but it's one of the few medicines prescribed for panic disorder. Most other benzodiazepines (including Alprazolam) are used primarily for generalized anxiety disorder and social anxiety disorder. Alprazolam binds to GABA receptors to produce these anxiolytic qualities.
Alprazolam tablets are available in .25 mg, 0.5 mg, 1 mg, and 2 mg strengths. Extended-release tablets are available in 0.5 mg, 1 mg, 2 mg, and 3 mg strengths. It also comes in a 1 mg/mL and 2 mg/mL liquid form. When used for anxiety, the usual starting dose is between 0.25 and 0.5 mg up to three times a day. Most people feel the effects within a few days.
