Clinical question

How effective are non-steroidal anti-inflammatory drugs (NSAIDs) for non-specific chronic low back pain in adults?

Bottom line

There was low quality evidence that NSAIDs were slightly better in reducing pain (3.3 points less on a 100-point scale for pain intensity) and disability (0.9 points better on a 0 to 24 scale) than placebo, but the effects were very small and possibly not clinically relevant. The studies with a low risk of bias showed no significant difference between NSAIDs and placebo. It was unclear whether NSAIDs were more effective than other drugs, and there was no evidence to show that one NSAID type was more effective than other types.

Caveat

Due to the inclusion of only randomised controlled trials, the relatively small sample sizes and the relatively short follow-up in most trials (9 days to 16 weeks), it was not possible to make firm statements about the occurrence of adverse events or the safety of NSAIDs for long-term use. Half of the included trials were supported by or included authors from pharmaceutical companies.

Context

Chronic low back pain is a common cause of pain and disability. NSAIDs are often used for treatment and are available both over the counter and on prescription in different types and chemical entities.
