Clinical overview
Acetaminophen (paracetamol) poisoning can cause severe delayed hepatotoxicity. Early risk assessment and timely N-acetylcysteine can prevent liver injury.
Important clinical update
US/Canada 2023 consensus: for a single acute ingestion with a reliable time, use the treatment nomogram from 4–24 hours; the 150 mg/L threshold at 4 hours declines on a semilog scale. Do not apply the nomogram to unknown-time or repeated ingestions; assess drug level, liver tests and clinical context and contact a poison centre. Consider country-specific treatment lines.
