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 Back and Body 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."

Methadone is used to treat moderate to severe pain when around-the-clock pain relief is needed for a long period of time. This medicine should not be used to treat pain that you only have once in a while or "as needed". Methadone is also used together with medical supervision and counseling to treat opioid addiction (eg, heroin or other morphine-like drugs).

Methadone is an opioid (narcotic) analgesic (pain medicine). It acts on the nervous system to relieve pain.

This medicine is available only with your doctor's prescription.
