THE INGESTION of a monoamine oxidase (MAO) inhibitor can induce a complex array of hypermetabolic signs, including hyperpyrexia, tachycardia, generalized muscle rigidity, tachypnea, metabolic acidosis, hypoxemia, and hypercapnia1 (J. W. Katalavis, MD, oral communication, November 1984). Toxicity of MAO inhibitors has previously been treated with standard therapy, ie, gastric lavage with activated charcoal, magnesium citrate, alkalinization of urine, and general support. Similar fulminant hypermetabolic states, such as neuroleptic malignant syndrome (NMS) and malignant hyperthermia (MH), respond to dantrolene sodium. Although two brief reports have been published,2,3 there has been no well-documented report of a fulminant hypermetabolic reaction to a MAO inhibitor that was treated with dantrolene sodium. We report a severe case of phenelzine (Nardil) overdose; the patient failed to respond to conventional therapy but dramatically improved with the administration of dantrolene sodium.
