We previously reported a near-fatal case in which the patient developed hyperthermia, disseminated intravascular coagulation, rhabdomyolysis, and acute renal failure.3The serotonin syndrome has been reported in patients who are treated with a combination of agents that markedly enhance brain serotonin activity. The most common serotonergic drug interactions associated with this syndrome include
