With acetaminophen, even when assuming the highest recommended doses were used, we found that children would have received on average 16% less acetaminophen than they would have had in hospital. (P = .048). With ibuprofen, assuming the lowest recommended doses were used, children would receive 25% less ibuprofen than as inpatients (P = .037). If the highest recommended doses were used, they would have taken 7% more ibuprofen than we would have found safe to prescribe (P = .06).Conclusions: Over-the-counter acetaminophen and ibuprofen come with dosing advice guided by age. Our analysis demonstrated that this could often be substantially different from the ideal dose, which is based on the child's weight. With the global trend of increasing body weight, we can expect this disparity to get bigger in the future. Good pain management is important in pediatric otolaryngology, but this result is relevant to all clinicians caring for children.
