Paracetamol overdose and hepatotoxicity at a regional Australian hospital: a 4‐year experience

Abstract

Annual admissions resulting from paracetamol OD almost doubled during the 4 years studied. The risk of a repeat paracetamol OD was highest within 4 weeks of the initial OD. Alcohol, benzodiazepines and antidepressants were commonly coingested. The strongest predictor of severe hepatotoxicity was delayed or no N-acetyl cysteine treatment in patients consuming greater than 10 g of paracetamol or with toxic serum paracetamol levels. A history of alcohol consumption did not appear to worsen outcomes.
