Although the interaction between methylene blue and serotonin reuptake inhibitors/serotonin norepinephrine reuptake inhibitors is well documented, there remains a paucity of literature on identifying patient groups who may be at risk for experiencing this interaction. Here, we report a case of methylene blue and venlafaxine-induced serotonin syndrome in a patient with cancer.
Keywords: adverse drug event; drug interaction; methylene blue; serotonin syndrome; venlafaxine.
