Fluoxetine for trichotillomania: an open clinical trial.

Of 17 adult patients with long-standing trichotillomania, 13 completed an 8- to 12-week open trial of fluoxetine, up to 80 mg per day. No patient had obsessive-compulsive disorder or major depression. We used the compulsions subscale of the Yale-Brown Obsessive-Compulsive Scale (YBOCS) to rate patients' hair-pulling behavior. The 13 completing patients' mean YBOCS score decreased significantly from 10.15 at baseline to 5.92 at the completion visit (Student's paired t = 4.82, df = 12, two-tailed p less than .001). Of these 13 patients, 5 experienced a 50 percent or greater decrease in their pulling behavior as measured by the YBOCS; 4 experienced between a 25 percent and 50 percent decrease. Three of the patients stopped pulling entirely, as did 2 of the 4 noncompleting patients. Three noncompleting patients discontinued treatment because of side effects, and 1 insisted on early use of behavior therapy. Comparative treatment trials elucidating the indications, risks, and expectable benefits of psychotherapeutic and pharmacological treatments are needed.
