What is Anestacon (Lidocaine Topical)?
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, hemorrhoids, and burns.
Lidocaine topical may also be used for purposes other than those listed in this medication guide.
What is the most important information I should know about Anestacon (Lidocaine Topical)?
An overdose of numbing medications can cause fatal side effects if too much of the medicine is absorbed through your skin and into your blood. This is more likely to occur when using a numbing medicine without the advice of a medical doctor (such as during a cosmetic procedure like laser hair removal). However, overdose has also occurred in women treated with a numbing medicine before having a mammography. Overdose symptoms may include uneven heartbeats, seizure (convulsions), coma, slowed breathing, or respiratory failure (breathing stops).
Your body may absorb more of this medication if you use too much, if you apply it over large skin areas, or if you apply heat, bandages, or plastic wrap to treated skin areas. Skin that is cut or irritated may also absorb more topical medication than healthy skin.
Use the smallest amount of this medication needed to numb the skin or relieve pain. Do not use large amounts of lidocaine topical, or cover treated skin areas with a bandage or plastic wrap without medical advice. Be aware that many cosmetic procedures are performed without a medical doctor present.
Keep both used and unused lidocaine topical patches out of the reach of children or pets. The amount of lidocaine in the skin patches could be harmful to a child or pet who accidentally sucks on or swallows the patch. Seek emergency medical attention if this happens.
