Clinical Significance
Acetaminophen is a common drug used in many formulations due to its analgesic and antipyretic properties. Chronic excessive use of acetaminophen can result in hepatotoxicity and nephrotoxicity. Overdosage can lead to severe hepatic damage and hepatic failure if untreated. Early diagnosis of acetaminophen induced hepatotoxicity is important since initiation of therapy within 16 hours of ingestion lessens the potential for hepatic injury and decreases the mortality rate.
