What is Lidoderm?

Lidoderm, the brand name for lidocaine patch, is applied to the skin once a day as needed for pain. It works by blocking your nerves from sending pain signals to the brain. Lidoderm is in a class of medications called topical local anesthetics. Topical means you apply it to your skin, and local means that it only affects the area where it is applied (as opposed to general anesthetics, which induce unconsciousness). Lidoderm is specifically intended to relieve pain after shingles infections, but you should not apply it to skin with open cuts or blisters.
