WHAT’S NEW
Second med adds nothing
This RCT found that adding cyclobenzaprine or oxycodone/aceta­minophen to naproxen for the treatment of nontraumatic, nonradicular acute LBP did not significantly improve functional assessment at seven days or three months after the initial ED visit. But it did increase adverse effects.

CAVEATS
Specific subset studied
This study was performed in a single urban ED and included a very specific subset of LBP patients, which limits the generalizability of the results. However, patients often present to primary care with similar LBP complaints, and the results of the study should reasonably apply to other settings.

The findings may not generalize to all NSAIDs, but there is no evidence to suggest that other NSAIDs would behave differently when combined with cyclobenzaprine or oxycodone/acetaminophen. In this analysis, only about one-third of patients used the as-needed medication more than once daily; another third used it intermittently or never.

CHALLENGES TO IMPLEMENTATION
Patients may expect more
Patients expect to receive prescriptions, and clinicians are inclined to write them if they believe doing so will help their patients. The evidence, however, does not demonstrate a benefit to these prescription-only medications for LBP.
