An editorial error occurred in this article by Dr Wallace and others (2002;19:202–5). In the flowchart, along the staggered overdose pathway, all doses should be described on a dose/kg/day and not a dose/kg basis. Also, patients who present after a paracetamol overdose with an unknown quantity of paracetamol should definitely be treated as though they may have taken a potentially hepatotoxic dose. The correct version of the flowchart is available on the journal web site (www.emjonline.com).
