A Case study of polypharmacy-induced serotonin syndrome in a cancer patient

Polypharmacy in cancer care can be complex and detrimental, particularly among younger patients, who can be easily overlooked. This report showcases a 54-year-old woman with cancer, treated for dapsone-induced methemoglobinemia with methylene blue (MB), subsequently developing serotonin syndrome (SS) due to concurrent serotonin-active medications. This case highlights the critical impact of polypharmacy, emphasizing the necessity for acute care providers to diligently assess medication interactions, especially in emergencies. It underscores the importance of considering alternative treatments and the vigilant monitoring of symptoms indicative of adverse drug interactions to ensure patient safety and optimize outcomes in complex therapeutic scenarios.
