1 Hepatotoxicity is rare when mild analgesics are used in normal therapeutic doses. 2 The potential of aspirin and salicylates to cause hepatotoxicity has been only recently recognized. 3 Salicylate hepatitis is often asymptomatic, and may only be revealed by finding elevated levels of aminotransferases. 4 Most cases have occurred in children or young adults with connective tissue diseases, who take high doses of salicylates for long periods. 5 Hepatic injury is not recognized as a complication of acute aspirin poisoning. 6 Following overdosage of paracetamol, a toxic intermediate metabolite causes acute hepatic necrosis which may be fatal. 7 Cysteamine, methionine and N‐ acetylcysteine confer protection against this severe liver damage, but the time between overdosage and treatment is critical. 8 The chronic therapeutic use of paracetamol should be considered a potential but very rare cause of active chronic hepatitis. 9 There is no clear evidence of phenacetin hepatotoxicity in man. 10 Phenylbutazone may cause liver injury and other analgesics can cause hypersensitivity reactions in which the liver is involved.
