However, acute liver failure induced by methamphetamine is rare, underreported, and not widely recognized among clinicians. Presenting this case highlights the potential severity of methamphetamine toxicity and aims to increase awareness of its hepatic complications in young, otherwise healthy patients.
Case Description/
Methods: A 22-year-old previously healthy male was brought to the emergency department unresponsive after suspected methamphetamine use. EMS found him apneic; bag-valve ventilation was initiated en route. On arrival, his GCS was 3, prompting immediate intubation and ICU admission.
Initial exam revealed intermittent posturing, sluggish pupils, and scattered skin lesions suggestive of intravenous drug use. Urine drug screen was positive for amphetamines and cannabinoids.
Laboratory work showed rapidly rising liver enzymes: AST peaked at 2,825 U/L and ALT at 3,589 U/L, with INR increasing to 1.6 and bilirubin peaking at 4.5 mg/dL. MELD score rose from 16 to 26 before improving. Acetaminophen levels were within normal limits; hepatitis panel was negative; and imaging was unremarkable. No hypotensive episodes occurred.
The patient was diagnosed with methamphetamine-induced ALF after excluding other causes. He also developed rhabdomyolysis and acute kidney injury, requiring five sessions of hemodialysis. With supportive care, liver and renal function progressively improved. At discharge, liver enzymes, INR, bilirubin, and renal function normalized, and dialysis was discontinued.
He was referred for rehabilitation. Follow-up labs confirmed complete hepatic recovery, and he remained sober at follow-up. confirmed complete recovery of liver function. The patient remained sober at follow-up. Discussion: This case highlights methamphetamine as a rare but potentially life-threatening cause of acute liver failure. Hepatotoxicity may result from direct cellular injury or ischemia due to methamphetamine-induced vasoconstriction and hyperthermia.
While liver transplantation is the mainstay for irreversible ALF, this case demonstrates that full recovery is possible in select patients with drug-induced liver injury, particularly when other etiologies are excluded and complications are promptly managed. Early recognition and aggressive supportive care may prevent the need for transplant in otherwise healthy individuals.
