Chronic pain, commonly defined as pain that lasts beyond 3 months and/or extends past normal tissue healing time, affects millions of US residents, with a 2021 prevalence of 21%. In this systematic review ... muscle relaxant medications were assessed. Muscle relaxants may be more beneficial than placebo for treating trigeminal neuralgia, painful cramps, and neck pain, but for fibromyalgia, low back pain, and other syndromes, they did not appear to be beneficial. Clinicians should be vigilant for adverse effects and consider deprescribing if pain-related goals are not met.
