What is topical lidocaine?

Donna Hill Howes, RN
Family Practitioner

Lidocaine is a local anesthetic (pain-reliever) available in a skin patch (Lidoderm) that helps control small areas of nerve pain. The patch is FDA-approved to treat postherpetic neuralgia, the nerve pain caused by a shingles infection. Patches are applied directly to the painful area. Studies have shown it to be an effective pain reliever for some people.
