This study reports the efficacy and safety of trazodone as an antidepressant drug in a national telematic multicenter outpatient open clinical trial. In less than 3 months, 1,700 patients completed a 1-month treatment and among them, 65% were considered as responders. The side effect profile of the drug included sedation, gastrointestinal discomfort and moderate hypotension. One case of trazodone-induced priapism is presented and briefly discussed.
