Topical NSAIDs Provide Effective Pain Relief Without Systemic Side Effects
Full Title
Topical NSAIDs for acute musculoskeletal pain in adults.
Summary
This Cochrane systematic review analyzed 61 studies with over 8,700 participants to evaluate the effectiveness and safety of topical NSAIDs for acute musculoskeletal pain such as sprains, strains, and overuse injuries. The study found that topical NSAID formulations including diclofenac, ibuprofen, and ketoprofen gels provided significantly higher rates of pain relief compared to placebo. The number needed to treat (NNT) for clinical success, meaning the number of patients who need to be treated for one to achieve at least 50% pain relief, was as low as 1.8 for diclofenac gel and 3.9 for ibuprofen gel. These effectiveness rates are probably similar to those provided by oral NSAIDs. Critically, local skin reactions were generally mild and transient, and there were very few systemic adverse events, meaning the gastrointestinal and other body-wide side effects associated with oral NSAIDs were largely avoided. This review supports topical NSAIDs as a safer alternative to oral NSAIDs for managing acute musculoskeletal pain, particularly for patients who need pain relief but want to avoid the risks of GI bleeding, liver damage, or impaired tissue healing associated with systemic NSAID use. Topical application delivers the medication directly to the injured area while minimizing exposure to the rest of the body.
