Why is this medication prescribed?
Lidocaine patches are used to relieve the pain of post-herpetic neuralgia (the burning, stabbing pains, or aches that may last for months or years after a shingles infection). Lidocaine is in a class of medications called local anesthetics. It works by stopping nerves from sending pain signals.
How should this medicine be used?
Lidocaine comes as a patch to apply to the skin. It is applied only once a day as needed for pain. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use lidocaine patches exactly as directed.
Your doctor will tell you how many lidocaine patches you may use at one time and the length of time you may wear the patches. Never apply more than three patches at one time, and never wear patches for more than 12 hours per day. Using too many patches or leaving patches on for too long may cause serious side effects.
To apply the patches, follow these steps:
