In persons with narcolepsy type 1, sudden withdrawal of antidepressants can cause status cataplecticus. We describe a 77-year-old female patient with long-standing history of narcolepsy type 1 complaining of recurrent short sudden episodes of whole-body paralysis, with preserved consciousness and memory. Episodes started an hour after her family invited her to celebrate Mother's Day. One week prior, patient had abruptly discontinued duloxetine. Cataplectic episodes resolved within 24 hours after resumption of duloxetine and treatment of hypokalemia. Status cataplecticus has been reported after withdrawal of venlafaxine, fluoxetine, and clomipramine. This is the first report of status cataplecticus due to duloxetine withdrawal. We review the pathophysiology of antidepressant withdrawal-induced status cataplecticus. In persons with narcolepsy type 1, physicians discontinuing any antidepressant should counsel on adverse effects of antidepressant withdrawal and reduce the dose in tapering manner.
