Uses of This Medicine:

Lidocaine topical jelly or ointment is used on different parts of the body to cause numbness or loss of feeling for patients having certain medical procedures. It is also used to relieve pain and itching caused by conditions such as sunburn or other minor burns, insect bites or stings, poison ivy, poison oak, poison sumac, minor cuts, or scratches.

Lidocaine viscous topical solution is also used to treat sore mouth or throat and also reduce gagging during the taking of X-ray pictures and dental impressions.

Lidocaine skin patch is used to relieve pain caused by shingles (postherpetic neuralgia).

Lidocaine belongs to the family of medicines called local anesthetics. This medicine prevents pain by blocking the signals at the nerve endings in the skin. This medicine does not cause unconsciousness as general anesthetics do when used for surgery.
