INTRODUCTION: Serotonin syndrome is a potentially life-threatening drug reaction that may occur following therapeutic drug use, inadvertent interactions between drugs, overdose of particular drugs, or the recreational use of certain drugs . It is caused by drug induced excess of intrasynaptic 5-hydroxytryptamine (5-HT) . We report a case of severe serotonin syndrome caused by interaction between a serotonin-norepinephrine reuptake inhibitor (SNRI) and street drug- `Molly’.
CASE PRESENTATION: A 41-year-old male with history of bipolar disorder was brought to ED for evaluation of extreme combativeness for one day. He was on risperidone and desvenlafaxine (an SNRI) and admitted to taking a “street drug -Molly”. Vitals revealed temperature of 40⁰C, pulse of 108bpm and blood pressure of 155/122mmhg. The patient was extremely agitated, diaphoretic and tremulous. Despite multiple intravenous lorazepam boluses, he remained combative. He was subsequently intubated and placed on a mechanical ventilator. Laboratory workup was significant for sodium of 118 meq/L, creatinine kinase (CK) of 3543U/L and myoglobin of 16,261ng/ml. Based on his clinical presentation, severe serotonin syndrome was diagnosed and managed with aggressive fluid hydration, cessation of serotonergic agent, sedation and neuromuscular blockade with cisatracurium. He subsequently developed massive rhabdomyolysis followed by acute renal failure requiring initiation of hemodialysis. With supportive care, his renal and neurological function improved and he was successfully extubated on day 19. He was discharged to a subacute facility on day 35.
DISCUSSION: "Molly" colloquially refers to MDMA(3,4-methylenedioxy-N-methylamphetamine) that is relatively free of adulterants. MDMA is a ring-substituted amphetamine derivative which indirectly stimulates the release and inhibits the reuptake of 5-HT . Its use especially in association with SSRIs or SNRIs has been associated with severe serotonin syndrome [1,3] requiring immediate and aggressive medical intervention.
CONCLUSIONS: Clinicians should be aware about the dangerous interaction between serotonergic agents and recreational drugs which could result in potentially lethal serotonin syndrome.
