Clinical Question

In patients with acute pain, does a higher dose of ibuprofen produce greater pain relief?

Bottom Line

Higher doses of ibuprofen for acute pain relief offer no more benefit at 60 minutes than a single 400-mg dose. The same has been shown for chronic treatment of osteoarthritis. A higher, anti-inflammatory dose is not needed. Another study showed equivalence between 200-mg and 400-mg doses of ibuprofen. (Level of Evidence = 2b)

Synopsis

The authors enrolled 225 adults who presented to a single emergency department with an acute painful condition (approximately 75% had musculoskeletal pain). The average pain score was between 6 and 7 on a scale of 1 to 10, with higher scores indicating higher pain. Using concealed allocation, patients were randomly assigned to receive a single dose of ibuprofen, 400 mg, 600 mg, or 800 mg. Using intention-to-treat analysis, pain scores after 60 minutes dropped to between 4.36 and 4.50 in all three groups. The study had 80% power to find a difference of at least 1.3 points among the groups.
