    Area of Science:

    • Clinical Toxicology
    • Pharmacology
    • Cardiovascular Medicine

    Background:

    • Methyldopa is a widely prescribed antihypertensive medication.
    • Overdose reports for methyldopa are notably infrequent in medical literature.
    • Accurate identification of overdose cases is crucial for patient management.

    Observation:

    • A case of methyldopa overdose was confirmed via quantitative blood analysis.
    • Clinical signs included coma, hypothermia, hypotension, bradycardia, and dry mouth.
    • These symptoms are typically associated with phenothiazine or tricyclic antidepressant toxicity.

    Findings:

    • The observed clinical presentation in methyldopa overdose can closely resemble psychotropic drug poisoning.
    • Quantitative blood analysis confirmed methyldopa as the causative agent.

  • The rarity of reported cases may lead to delayed diagnosis.

    • Implications:

    • Clinicians should consider methyldopa overdose in patients presenting with symptoms mimicking psychotropic drug toxicity.
    • Increased awareness can improve diagnostic accuracy for rare overdose cases.
    • This case highlights the importance of comprehensive toxicological assessment in overdose scenarios.
