Risk of wheezing and asthma exacerbation in children treated with paracetamol versus ibuprofen: A systematic review and meta-analysis of randomised controlled trials

Abstract

//Background:Paracetamol and ibuprofen are the most commonly used medications for fever and painmanagement in children. While the efficacy appears similar with both drugs, there are contradictory findings relatedto adverse events. In particular, incidence of wheezing and asthma among children taking paracetamol comparedto ibuprofen, remain unsettled. //Methods:We conducted a meta-analysis of randomized controlled trials (RCTs) that compared wheezing andasthma exacerbations in children taking paracetamol versus ibuprofen. A comprehensive search was conducted infive databases. RCTs reporting on cases of wheezing or asthma exacerbations in infants or children after theadministration of paracetamol or ibuprofen were included. The pooled effect size was estimated using the Peto's odds ratio. //Results:Five RCTs with 85,095 children were included in the analysis. The pooled estimate (OR 1.05; 95%CI 0.76-1.46) revealed no difference in the odds of developing asthma or presenting an exacerbation of asthma in childrenwho received paracetamol compared to ibuprofen. When the analysis was restricted to RCTs that examined theincidence of asthma exacerbation or wheezing, the pooled estimate remained similar (OR 1.01; 95%CI 0.63-1.64).Additional bias adjusted quality effect sensitivity model yielded similar results (RR 1.03; 95%CI 0.84-1.28). //Conclusion:Although, Ibuprofen and paracetamol appear to have similar tolerance and safety profiles in terms ofincidence of asthma exacerbations in children, we suggest high quality trials with clear definition of asthmaoutcomes after receiving ibuprofen or paracetamol at varying doses with longer follow-up are warranted for anyconclusive finding Show more
