Trazodone demonstrates comparable efficacy with the tricyclic antidepressant agents (TCAs) but produces fewer of the untoward side effects associated with these drugs. All of the TCAs are potentially lethal when taken in overdose; they cause serious cardiovascular side effects; produce anticholinergic effects, which often are severe enough to result in discontinuation of medication; and impair cognition, especially in elderly patients. In contrast, trazodone is relatively safe when taken in overdose; no deaths have been reported to the manufacturer when trazodone was the only agent taken. Trazodone produces fewer and milder cardiovascular disturbances and anticholinergic effects than TCAs. If anticholinergic side effects do occur then they are rarely bothersome enough to result in discontinuation of therapy. In addition, cognitive skills, even in elderly patients, are less impaired in patients receiving trazodone therapy than in patients receiving TCA drugs. Although trazodone therapy has been associated with lethargy, dizziness, drowsiness, and confusion in some patients, symptoms have been mild and can be further minimized by administering the drug either after meals or once daily at bedtime.
