Qutenza patches contain capsaicin. 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.

Qutenza patches are used to treat nerve pain (neuralgia) in people who have had herpes zoster, or "shingles."
