To the editor: Cyclobenzaprine (Flexeril; Merck Sharp & Dohme, West Point, Pennsylvania) is a central-acting skeletal muscle relaxant structurally related to the tricyclic antidepressant amitryptiline. Severe cyclobenzaprine poisoning from intentional overdose has been reported in only three previous cases (1). These patients presented with anticholinergic signs, including dry skin and mucous membranes, and an organic brain syndrome that reversed with treatment with physostigmine. We report the case of a patient with cyclobenzaprine poisoning who presented atypically with profound diaphoresis.
