About this episode
Contributor: Aaron Lessen, MD Educational Pearls: Recorded March 2025 What is the best treatment for a fever? Tylenol? Ibuprofen? Combined? Alternating the two? The journal Pediatrics aimed to answer this question with a meta-analysis of 31 randomized controlled trials including 5,009 febrile children. Results showed that both combined and alternating acetaminophen/ibuprofen regimens were significantly more effective at reducing fever at 4 and 6 hours compared with acetaminophen alone, with numbers needed to treat (NNT) of 3 and 4, respectively. High-dose ibuprofen alone also offered modest benefit (NNT 8). What dose should I use? Oral acetaminophen 10 to 15 mg/kg Every 4–6 hours as needed Do not exceed 75 mg/kg/day (or 4,000 mg/day maximum for older/larger kids) Oral ibuprofen 5 to 10 mg/kg Every 6–8 hours as needed Do not exceed 40 mg/kg/day (or 2,400 mg/day maximum for older/larger kids) References De la Cruz-Mena JE, Veroniki AA, Acosta-Reyes J, Estupiñán-Bohorquez A, Ibarra JA, Pana MC, Sierra JM, Florez ID.
