  • It results from excessive serotonergic activity, primarily affecting the central nervous system.
  • Manifestations include altered mental status, autonomic dysfunction, and neuromuscular abnormalities.

Purpose of the Study:

  • To describe the clinical characteristics, etiology, and management of serotonin syndrome.
  • To emphasize diagnostic criteria and treatment strategies for healthcare providers.

Main Methods:

  • Literature review of reported cases and clinical studies.
  • Analysis of drug interactions leading to serotonin syndrome.
  • Summary of current treatment guidelines and supportive care measures.

Main Results:

  • Serotonin syndrome typically occurs with the co-administration of two or more serotonergic agents.
  • Symptoms usually appear shortly after initiating or increasing the dose of a serotonergic medication.
  • The condition is often self-limiting, resolving within hours to days after drug withdrawal.

Conclusions:

  • High index of suspicion and thorough patient drug history are crucial for diagnosis.
  • Management primarily involves discontinuing the causative agent(s) and providing supportive care.
  • While specific antidotes are not routinely used, cautious administration of certain agents may be considered in severe cases.
