Serotonin syndrome (SS) is an adverse drug reaction resulting from therapeutic drug use, intentional selfpoisoning, or unintentional drug-drug interactions. It is especially common among patients who are prescribed with psychiatric drugs. The condition, if left untreated, can be potentially life-threatening. This case report outlines a patient with depression who developed SS after consuming a single normal dose of venlafaxine and magnesium valproate. To date, no similar cases have been reported in the literature to the best of our knowledge.
