Treatment of REM sleep behavior disorder with trazodone: report of 3 cases

Rapid eye movement sleep behavior disorder is a sleep disturbance characterized by the absence of regular paralysis during rapid eye movement sleep, accompanied by dream enactment behavior. The available pharmacotherapy options for treating rapid eye movement sleep behavior disorder are limited, and the utilization of antidepressants has yielded mixed results. We report 3 cases of isolated rapid eye movement sleep behavior disorder improved with trazodone. Doses of 50-100 mg of trazodone at bedtime over 4-6 months resulted in significant clinical improvement. These cases highlight that trazodone could serve as a treatment for isolated rapid eye movement sleep behavior disorder that does not respond to traditional treatments at submaximal dosages.
