Serotonin Syndrome Induced by Electroconvulsive Therapy

Clinical Presentation and Management

• Serotonin syndrome presents with a triad of symptoms, including mental status changes, neuromuscular hyperactivity, and autonomic instability, typically developing within 24-48 hours after the triggering event, according to the American Academy of Child and Adolescent Psychiatry and Praxis Medical Insights 1
• Symptoms can progress to fever, seizures, arrhythmias, unconsciousness, and potentially death, emphasizing the need for prompt recognition and treatment, as recommended by Praxis Medical Insights 1
• The American Academy of Child and Adolescent Psychiatry recommends considering temporarily discontinuing serotonergic medications before initiating ECT when clinically feasible, to minimize the risk of serotonin syndrome 2
• If serotonin syndrome is suspected, immediately discontinue all serotonergic agents and provide supportive care, including IV fluids and cardiac monitoring, as advised by Praxis Medical Insights 1
• Consider serotonin antagonists such as cyproheptadine for severe cases, as suggested by Praxis Medical Insights 1
• When restarting serotonergic medications after ECT, begin with low doses and titrate slowly, as recommended by Praxis Medical Insights 1

High-Risk Medication Combinations

• Particular caution is needed when ECT is combined with multiple serotonergic agents simultaneously, MAOIs, opioids with serotonergic properties, lithium, or trazodone, as warned by the Journal of the American Academy of Child and Adolescent Psychiatry and Praxis Medical Insights 1, 2, 3
