Key takeaways
Capsaicin (Capzasin-HP, Salonpas-Hot) and lidocaine 5% patch (Lidoderm) are both medications used to relieve pain, but they belong to different medication classes and have distinct uses. Capsaicin is a topical analgesic available over-the-counter (OTC) and is used for minor aches and pains in muscles and joints, such as those caused by arthritis and backaches. It comes in forms like cream, liquid, and patch. Lidoderm, on the other hand, is a prescription-only patch used to relieve nerve pain caused by a shingles. Capsaicin can cause a burning sensation and should not be applied to sensitive areas. Lidoderm patch is applied directly to the painful area of your skin once a day, and it can be worn for up to 12 hours in a 24-hour period. Capsaicin is generally well-tolerated with few side effects, whereas Lidoderm can cause temporary skin irritation, redness, and a mild burning sensation where the patch is applied.
