A 59-year-old male with a history of alcohol abuse presented with altered mental status. Upon examination, he was hypertensive and lethargic, and laboratory results revealed severe transaminitis, coagulopathy, and lactic acidosis, despite having normal serum alcohol levels. Additionally, his urine drug screen tested positive for methamphetamine. Following the exclusion of infectious, autoimmune, and other common causes of acute hepatitis, a diagnosis of methamphetamine-induced acute hepatitis was established. A non-acetaminophen toxicity N-acetylcysteine (NAC) protocol was initiated, resulting in a positive response with improvement in mentation and a decrease in liver enzyme levels. This case emphasizes the potential effectiveness of NAC in treating amphetamine-induced liver injury, supported by the limited available literature on the subject.
Keywords: acute liver failure; drug toxicity; drug-induced acute liver failure; methampheatmine; n-acetylcysteine.
