Evidence of benefit is lacking for low back pain relief with muscle relaxants

Do muscle relaxants provide relief for nonspecific lower back pain?

Stick with nonsteroidal anti-inflammatories for the treatment of low back pain. Despite being used for almost 50 years to treat low back pain, the evidence supporting benzodiazepine or non-benzodiazepine “muscle relaxants” is of low certainty. None of the treatments will produce a clinically important difference over placebo treatment.
