Management of acetaminophen toxicity.
Acetaminophen poisoning is a significant medical problem in the United States and is frequently managed by family physicians. The primary clinical effect of acetaminophen poisoning is hepatotoxicity that occurs after ingestion of large single doses of acetaminophen or after ingestion of smaller doses in patients with hepatic metabolism that is altered by drugs or concurrent medical conditions. Hepatocellular damage is probably caused by accumulation of the toxic intermediate metabolite N-acetyl-p-benzoquinoneimine when hepatic glutathione stores are depleted. Treatment of acetaminophen poisoning consists of preventing gastrointestinal absorption of the drug, use of the antidote N-acetylcysteine and supportive care.
