Uses for dibucaine

Dibucaine is 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.

Dibucaine belongs to a group of medicines known as topical local anesthetics. It deadens the nerve endings in the skin. This medicine does not cause unconsciousness as general anesthetics do when used for surgery.

This medicine is available without a prescription; however, your doctor may have special instructions on the proper use and dose for your medical problem.
