Why is this medicine prescribed?
Nonprescription (over-the-counter) capsaicin patches (Aspercreme Warming, Salonpas Pain Relieving Hot, others) are used to relieve minor pain in muscles and joints caused by arthritis, backaches, muscle strains, bruises, cramps, and sprains. Prescription capsaicin patches (Qutenza) are used to relieve the pain of postherpetic neuralgia (PHN; the burning, stabbing pain or aches that may last for months or years after an attack of shingles). Prescription capsaicin patches (Qutenza) are also used to relieve the pain of diabetic neuropathy (numbness or tingling due to nerve damage in people who have diabetes). Capsaicin is a substance that is found in chili peppers. It works by affecting nerve cells in the skin that are associated with pain, which results in decreased activity of these nerve cells and a reduced sense of pain.
Are there other uses for this medicine?

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children and pets. Store it at room temperature.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
What other information should I know?
Do not let anyone else use your medication. Ask your pharmacist any questions you have about refilling your prescription.
