Zostrix is used to temporarily reduce the symptoms of joint and muscle pain caused by arthritis, sprains, strains, bruises and back aches. Zostrix is also sometimes used to treat nerve pain causes by Shingles.
The generic name of Zostrix is Capsaicin Topical. Interesting enough Capsaicin is what makes chili peppers hot, but it can be used topically to cause the sensation of heat, which activates nerve cells to relieve join and muscle pain. Over time and through regular use, the heating effect can reduce the amount of substance P in the body. Sustance P is a chemical that acts as a pain messenger throughout the body.
Wash your hands thoroughly before and after using Zostrix. Do not use Zostrix if you have an allergy to chili peppers.
