What is lidocaine and epinephrine?

Lidocaine and epinephrine is a type of local anesthetic that causes numbness and loss of feeling. It is used during medical procedures or as a home relief for mild skin discomfort. This anesthetic is available by prescription only and comes in the form of injections and skin patches. Lidocaine and epinephrine work by deadening nerves in the skin; because nerve endings cannot work properly and send messages of pain, you do not feel discomfort. Medical procedures that involve the skin or tissues will require the intense numbing strength of lidocaine and the long-lasting effects of epinephrine, which will be administered by a doctor.
