According to this new article from JAMA, the addition of Percocet or Flexeril to Naproxen does not improve functional outcomes in acute low back pain. The article compared functional outcomes in lower back pain at 1 and 3 weeks between Naproxen, Flexeril, and Percocet. Via a randomized, double-blind study in NYC, 323 patients were randomized to Naproxen + Placebo, Naproxen + Flexeril, and Naproxen + Percocet. Using an improvement in the Roland-Morris Disability Questionnaire (RMDQ), the study found that adding cyclobenzaprine or oxycodone/acetaminophen to naproxen alone did not improve functional outcomes or pain at 1-week follow-up. These findings do not support use of these additional medications in this setting.
