Treatment of paracetamol intoxication with N-acetylcysteine (NAC) is standard in Denmark. NAC is considered safe with relatively few side effects. It is recommended that all patients be treated irrespective of paracetamol dose or time from intoxication to treatment start. Consequently a higher number of patients will be treated with NAC than with previous regimens based on plasma concentrations of paracetamol. In this retrospective study we evaluated the incidence of side effects of NAC in 310 patients admitted to the Department of Hepatology, Rigshospitalet, Copenhagen, over a four-year period (1.1.1994-31.12.1997). Twenty-six (8.4%) patients developed side effects. Side effects were anaphylactoid, mainly from skin (25 rash, pruritus or flushing), in rare cases more serious (four bronchospasm, three angioedema, one hypotension). None were life-threatening and all patients received the full course of NAC. In all cases the recommended treatment with antihistamine or steroids against adverse effects was administered. We conclude that treatment with NAC is safe. Accordingly we find no reason to change the recommendation for treatment of paracetamol intoxication in Denmark. |
