title: Chronic acetaminophen toxicity: a case report and review of the literature.
abstract: Acetaminophen is one of the most frequently used medications in the United States. While usual dosing of acetaminophen is considered harmless, both acute and chronic overdoses can be fatal. The majority of reported cases of chronic acetaminophen toxicity in adults occur in chronic alcohol abusers, patients taking P450-inducing medications, or following massive dosing. We describe a case of toxic hepatitis free of the aforementioned risk factors associated with chronic ingestion of moderately excessive doses of acetaminophen. Our patient ingested approximately 5.0 to 6.5 g of acetaminophen daily for 6 to 8 weeks via multiple medications. The inclusion of acetaminophen in numerous medications combined with the frequency of use of acetaminophen necessitates an increased concern for not only acute but also chronic acetaminophen toxicity.
