Ibuprofen overdose.

Enquiries about the management of patients possibly suffering from ibuprofen overdose account for over 5% of the total enquiry workload of the London Centre of the United Kingdom National Poisons Information Service. Unlike overdose with aspirin and paracetamol, no additional pathophysiological findings have been reported in ibuprofen overdose and all the demonstrated toxic effects relate to its known pharmacological actions and the effects of accumulation of the two acidic metabolites, 2-hydroxyibuprofen and 2-carboxylibuprofen. The most striking finding in reported cases is that the great majority of patients suffer no or only mild symptoms.
