Capsaicin, the ingredient in chili peppers that makes them hot, is also used in a variety of medications to treat muscle and joint pain. When used on the body in cream or lotion form, capsaicin causes a heating sensation while also activating various nerve cells. Substance P, the chemical that acts as the pain messenger in the body, is reducible with frequent use of capsaicin. Capzasin-HP can be taken up to four times per day and should not be applied to open wounds, notes Drugs.com.
Salicylate is the same ingredient used in other pain-relieving products, such as aspirin. Menthol is used as a counterirritant because it causes a cooling sensation that distracts the mind from pain, explains WebMD. Menthoderm should not be used by women who are pregnant or breastfeeding or by people who are allergic to aspirin. Menthoderm should not be used more than three or four times a day and not be applied to open wounds. Menthoderm is meant to be applied in a thin layer, but patients may use up to three thin layers depending on the level of pain, states Drugs.com.Learn more about Pain & Symptoms
