Effectiveness of alprazolam in the treatment of chronic pain: results of a preliminary study.

One hundred chronic pain patients were begun on alprazolam, 1.5 mg/day. No other medication changes or therapeutic interventions were made. Sixteen patients were lost to follow-up and 1 oncology patient died. Of the 83 patients who were evaluated at 12 weeks, 61 (73.5%) showed improvement, and only 5 had discontinued the medication because of side effects. The average score of all patients had decreased from 3.6 to 2.2 on a verbal analog scale that rated pain severity from 0 to 5. There was no difference in response among the various diagnostic groups represented in the study population.
