Avoid touching the sticky side of a lidocaine skin patch while applying it.

Avoid accidentally injuring treated skin areas while they are numb. Avoid coming into contact with very hot or very cold surfaces.

It is not likely that other drugs you take orally or inject will have an effect on topically applied lidocaine. But many drugs can interact with each other. Tell each of your health care providers about all medicines you use, including prescription and over-the-counter medicines, vitamins, and herbal products.

Lidocaine is a local anesthetic (numbing medication). It works by blocking nerve signals in your body.

Lidocaine topical (for use on the skin) is used to reduce pain or discomfort caused by skin irritations such as sunburn, insect bites, poison ivy, poison oak, poison sumac, and minor cuts, scratches, or burns. Lidocaine topical is also used to treat rectal discomfort caused by hemorrhoids.

Lidocaine topical may also be used for purposes not listed in this medication guide.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

An overdose of numbing medicine can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. Overdose symptoms may include uneven heartbeats, seizure (convulsions), slowed breathing, coma, or respiratory failure (breathing stops).

Lidocaine applied to the skin is not likely to cause an overdose unless you apply more than the recommended dose.
