Lidocaine patches (5%) are a type of prescription topical local anesthetic used to relieve pain caused by nerve damage in the skin, notably postherpetic neuralgia (shingles-related pain). Each patch delivers lidocaine directly to the affected area, blocking sodium channels in nerve endings and reducing the transmission of pain signals to the brain. This makes lidocaine patches ideal for targeted relief without affecting the rest of the body.
They provide a convenient and non-systemic option for chronic localized pain relief and are typically applied to intact skin over the most painful area.
How To Use:
Typically applied up to 3 patches at once to cover the affected area. Leave on for no more than 12 hours within a 24-hour period. Patches can be trimmed to fit the size and shape of the painful region. Only apply to clean, dry, and unbroken skin. Avoid exposure to water (swimming, bathing) while wearing patches.
Precautions:
Not intended for use on open wounds or irritated skin. Dispose of used patches safely and keep out of reach of children. Do not use more than directed to avoid systemic lidocaine absorption.
