Capsaicin OA indication is recommended for knee OA only.

Capsaicin OA indication is recommended for knee OA only.

• A. Hand OA
• B. Hip OA
• C. Knee OA only
• D. General OA in all joints

Answer: (C)

Capsaicin provides pain relief by acting on peripheral nerve endings and depleting substance P, which reduces pain signaling from the joint. In osteoarthritis, the strongest and most consistent evidence for topical capsaicin is in knee OA, where multiple trials show modest but real pain relief with ongoing use. By contrast, the data for hand OA are less consistent, and hip OA has fewer studies showing clear benefit, so the indication is not as well established for those joints. That’s why the recommended use is for knee OA only. In practice, expect a local burning or stinging sensation at first, and follow directions on how often to apply (often several times daily) and precautions—avoid applying to broken skin, wash hands after use, and keep away from eyes or mucous membranes. The onset of noticeable relief may take a couple of weeks with continued use.
