Summary

Mefloquine (Lariam) can cause severe neuropsychiatric reactions, including suicide. Physicians should consider this risk, especially with unusual behavior or suspected suicide, and test for the drug in toxicological exams.

Area of Science:

  • Neuropsychiatry
  • Pharmacology
  • Toxicology

Background:

  • Mefloquine (Lariam) is an antimalarial drug recommended for travelers to high-risk areas.
  • Since its introduction, serious neurologic and psychiatric adverse events have been reported.
  • Physicians must weigh the benefits of malaria prevention against potential drug-associated risks.

Observation:

  • A 27-year-old man died from a fatal head wound, initially suspected as homicide.
  • The deceased exhibited atypical behavior and acute psychosis.
  • Toxicological analysis confirmed mefloquine use.

Findings:

  • The case suggests suicide as a severe neuropsychiatric reaction to mefloquine treatment.
  • Mefloquine-induced psychosis can lead to atypical behaviors and fatal outcomes.

  • Identifying mefloquine exposure is crucial in cases of unexplained suicide or psychosis.

    • Implications:

    • Clinicians must be vigilant for severe psychiatric complications of mefloquine.
    • Inquire about recent travel and antimalarial use, even months prior.
    • Mefloquine testing is essential in forensic toxicology for suspected drug-related deaths.
