• INTRODUCTION
    • Intravenous lipid emulsion (ILE) resuscitation is now frequently being used for severe overdoses due to lipophilic drugs. However, the optimal dose, duration, and safety are still unclear.
  • CASE REPORT
    • A patient with refractory cardiovascular collapse following an amitriptyline overdose was treated with ILE with initial improvement. Instability recurred after ILE discontinuation and lipid therapy was restarted, but high-dose treatment was complicated by severe lipemia. A low-dose infusion was instead used, and the patient did not experience further toxicity despite amitriptyline levels in the toxic range for 21 days. He survived to discharge without long-term sequelae.
  • DISCUSSION
    • A low-dose infusion of ILE was well tolerated and may have successfully prevented recurrent toxicity in a case of severe tricyclic antidepressant overdose.
