Xylocaine belongs to a group of medicines known as topical local anesthetics. Topical anesthetics are 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, and minor cuts and scratches.
Topical anesthetics deaden the nerve endings in the skin. They do not cause unconsciousness as do general anesthetics used for surgery.
Most topical anesthetics are available without a prescription; however, your doctor may have special instructions on the proper use and dose for your medical problem.
