Capsaicin is the active ingredient in chili peppers that makes them hot. Capsaicin is used in medicated creams and lotions to relieve muscle or joint pain.

Capsaicin used on the body causes a sensation of heat that activates certain nerve cells. With regular use of capsaicin, this heating effect reduces the amount of substance P, a chemical that acts as a pain messenger in the body.

Capzasin-P is used for temporary relief of muscle or joint pain caused by strains, sprains, arthritis, bruising, or backaches. This medicine is also used to treat nerve pain (neuralgia) in people who have had herpes zoster, or "shingles."

Capzasin-P may also be used for purposes not listed in this medication guide.
