Episode notes
Complexity of Causes
- Serotonin syndrome often arises from drug interactions rather than overdose alone.
- Even complex multi-drug interactions can trigger toxicity, necessitating careful medication review.
Classic Triad and Spectrum
- Serotonin syndrome presents as a triad: mental status changes, sympathetic hyperactivity, and neuromuscular excitation.
- This constellation can range from mild symptoms to severe, life-threatening illness.
Rapid Onset and Resolution
- Serotonin syndrome usually develops rapidly within 6 to 24 hours of medication change or overdose.
- Symptoms improve quickly, often within 24 hours, after stopping offending drugs, aiding diagnosis.
