Serotonin syndrome management includes which of the following actions?

• A. Discontinue serotonergic medications and provide supportive care.
• B. Increase serotonergic medications.
• C. Use antipsychotics as first-line.
• D. Observe without intervention.

Answer: (A)

The key idea is that serotonin syndrome is a medical emergency caused by too much serotonergic activity, so the most important step is to stop all serotonergic medications immediately. Discontinuing the offending agents removes the ongoing source of excess serotonin and halts further progression of symptoms.

After stopping the drugs, management centers on supportive care and symptom control. This includes close monitoring of vital signs, ensuring adequate IV fluids, cooling measures and fever control for hyperthermia, and using benzodiazepines to calm agitation, reduce tremors, and temper autonomic arousal. In moderate to severe cases, a serotonin antagonist such as cyproheptadine can be used to counteract serotonin effects. More intensive care may be required if the patient shows signs of severe autonomic instability or airway compromise.

Antipsychotics are not recommended as first-line treatment because they don’t address the underlying serotonin excess and can complicate the clinical picture. Simply observing without intervention is unsafe due to the potential for rapid deterioration.
