A hemodialysis male patient exhibited depressive symptoms and trazodone was prescribed orally. Although his depressive symptoms disappeared, he gradually presented with parkinsonism. His parkinsonism improved within a week after stopping trazodone. The clinical course strongly suggested that it was induced by trazodone. However, there is no report on antidopaminergic side effects of parkinsonism. This case suggests that antidopaminergic effects leading to parkinsonism need to be considered in patients on hemodialysis that are taking trazodone.
