Anbesol (Benzocaine) is a local anesthetic (numbing medication). It works by blocking nerve signals in your body. Benzocaine topical is used to reduce pain or discomfort caused by minor skin irritations, sore throat, sunburn, teething pain, vaginal or rectal irritation, ingrown toenails, hemorrhoids, and many other sources of minor pain on a surface of the body. Benzocaine is also used to numb the skin or surfaces inside the mouth, nose, throat, vagina, or rectum to lessen the pain of inserting a medical instrument such as a tube or speculum. There are many brands and forms of benzocaine topical available and not all brands are listed on this leaflet.
