Introduction: Caffeine overdose, while uncommon, can be life threatening with hemodynamic and neurological complications and often requires intensive monitoring and critical management.

Case report: We report a case of a 23-year-old male who ingested approximately 24 g of caffeine in a suicidal attempt and developed cardiopulmonary complications. He was resuscitated, and hemodialysis was performed with successful recovery.

Conclusion: Hemodialysis appears to effectively remove caffeine from the blood system and can be lifesaving in severe caffeine overdose.
