Association of Acetaminophen Hepatotoxicity With Fasting and Ethanol Use

Abstract

Acetaminophen hepatotoxicity after a dose of 4 to 10 g/d was associated with fasting and less commonly with alcohol use. Patients who developed hepatoxicity after taking acetaminophen doses of greater than 10 g/d for therapeutic purposes were alcohol users. Acetaminophen hepatotoxicity after an overdose appears to be enhanced by fasting in addition to alcohol ingestion.
