Warming creams for back and joint pain

Over-the-counter creams with low-concentration capsaicin or menthol marketed for back pain, osteoarthritis and bruises. Cochrane (Derry 2017) found a clinically insignificant effect of low-dose capsaicin in osteoarthritis. AAOS, EULAR and SER do not include such rubs in first-line recommendations for acute musculoskeletal pain.

Marketing claims without evidence base

The drug is promoted for these uses outside international guidelines. Each entry below is analyzed against AEMPS, FDA, EMA, Cochrane and major RCTs.

FCapsaicinNot recommended · Selective TRPV1 agonist, topical analgesic for neuropathic painCapsaicin is a selective TRPV1 agonist with proven efficacy only in neuropathic pain as the high-dose 8% patch (Qutenza). Low-dose warming creams with capsaicin (Espol, Nicoflex, several OTC combinations) are marketed for «back pain, osteochondrosis, muscle pain, bruises». Cochrane (Derry 2017) on topical capsaicin for chronic pain: evidence quality is low and the effect is clinically insignificant. AAOS, EULAR and SER do not include such creams in first-line recommendations for acute musculoskeletal pain. If a capsaicin cream was prescribed for acute back pain, osteochondrosis or a bruise, consider seeking a second opinion.
