Dosage Calculation

  • For adolescents weighing more than 40 kg, adult dosing guidelines apply, with a standard ibuprofen dosage of 10 mg/kg per dose, according to the American Family Physician 1, 2

Administration Guidelines

  • Administer ibuprofen every 8 hours (3 times daily), with a maximum of 3 doses in a 24-hour period, as recommended by the Anaesthesia guidelines 1

Safety Considerations

  • Monitor for potential side effects including gastrointestinal upset, dizziness, and rash, as advised by the American Family Physician 3
  • Use ibuprofen with caution in patients with a history of peptic ulcer disease, renal impairment, cardiovascular disease, or bleeding disorders, according to the Journal of the National Comprehensive Cancer Network and the Journal of the American Geriatrics Society 4, 5

Common Pitfalls to Avoid

  • Avoid combining ibuprofen with other NSAID medications or acetaminophen-containing products without adjusting doses, as warned by the Journal of the National Comprehensive Cancer Network 6
  • Be aware of "hidden sources" of NSAIDs in combination medications, as noted by the Journal of the American Geriatrics Society 5

Alternative Considerations

  • If ibuprofen is contraindicated or ineffective, consider acetaminophen 10-15 mg/kg every 6 hours, as suggested by the Anaesthesia guidelines 1
