Paracetamol poisoning is a common cause of liver damage. Activated charcoal is best for reducing absorption, while N-acetylcysteine may help severe cases, but evidence for optimal use is limited.

Area of Science:

  • Toxicology
  • Hepatology
  • Clinical Pharmacology

Background:

  • Paracetamol (acetaminophen) poisoning is a frequent cause of liver toxicity.
  • Interventions include absorption inhibition, removal, antidotes, and liver transplantation.

Purpose of the Study:

  • To evaluate the benefits and harms of various interventions for paracetamol overdose.
  • To identify effective treatments for paracetamol-induced hepatotoxicity.

Main Methods:

  • Systematic review of randomized clinical trials and observational studies up to December 2005.
  • Meta-analysis of outcomes including mortality, liver transplantation, clinical symptoms, and hepatotoxicity.

Main Results:

  • Limited high-quality randomized trials exist for paracetamol overdose interventions.

  • Activated charcoal shows a favorable risk-benefit ratio for reducing absorption.
  • N-acetylcysteine appears superior to placebo and some other antidotes, but optimal protocols and comparisons to methionine are unclear.
  • N-acetylcysteine may reduce mortality in fulminant hepatic failure; liver transplantation is a life-saving option in severe cases.

    • Conclusions:

    • A significant lack of robust randomized trials complicates evidence-based recommendations for paracetamol overdose interventions.
    • Activated charcoal is recommended for reducing paracetamol absorption.
    • N-acetylcysteine is indicated for overdose, but precise selection criteria and optimal regimens require further research.
    • Liver transplantation decisions for fulminant hepatic failure necessitate careful consideration of selection criteria and long-term outcomes.
