Description
Indications
Topical capsaicin is employed to alleviate minor pain in muscles and joints stemming from conditions such as arthritis, backaches, muscle strains, bruises, cramps, and sprains. Capsaicin, a substance found in chili peppers, is the active component in this topical application. It operates by influencing nerve cells in the skin that are linked to pain perception, leading to decreased activity of these nerve cells and a diminished sensation of pain.
Uses and Dosage
Capsaicin is available in various forms, including ointment, cream, gel, oil, and a topical solution, with different strengths for application to the skin. Typically, it is used as needed, as indicated on the product label or as directed by your doctor.
Use topical capsaicin precisely as directed, avoiding using more or less of it or using it more frequently than instructed by the package guidelines.
To apply topical capsaicin, take a small amount of ointment, cream, oil, or topical solution and spread it thinly over the affected area of the skin. Gently rub it in, and avoid applying it to folds of the skin.
Do not use topical capsaicin on skin that is broken, damaged, cut, infected, or covered by a rash. Additionally, refrain from wrapping or bandaging the treated area.
This medication is intended for use only on the skin. Avoid getting topical capsaicin into your eyes, nose, or mouth, and do not swallow it.
After application, wash your hands with soap and water to remove any residual medicine. If you’ve applied topical capsaicin to your hands, wait for 30 minutes before washing them. Refrain from touching your eyes, nose, or mouth until your hands are washed.
While using topical capsaicin, shield the treated area from direct heat, such as heating pads, electric blankets, hair dryers, and heat lamps. It’s advisable not to apply topical capsaicin immediately before or after showering, taking a bath, swimming, or engaging in vigorous exercise.
If your pain worsens, improves and then worsens again, or lasts longer than 7 days, stop using topical capsaicin and contact your doctor.
