The literature on alprazolam is reviewed. It is concluded that it is an effective anxiolytic but that it is not an antidepressant. When used in sufficiently high dosage it can block panic attacks, but it is not the only antipanic agent available. It may be used as an alternative to other benzodiazepines in the acute detoxification of alcoholics. It should be avoided where there is strong individual likelihood of abuse. Chronic usage (more than a few weeks) demands a very slow tapering of dosage. Carbamazepine may ameliorate withdrawal symptoms. The use of alprazolam in other conditions remains unproven.
