Benzocaine can be the only active ingredient in oral treatments that relieve sore throat or address

mouth pain caused by cold sores, canker sores, teething, and other issues. It also can be

combined with other active ingredients in oral treatments that not only relieve mouth and throat

pain, but also protect irritated areas, provide a soothing coating, or relieve dryness.

While oral discomfort treatments containing benzocaine are intended to be used in and around

the mouth, there are other topical benzocaine medicines that should only be used externally, or on

the outer surface of the body (not near or in the mouth). For example, benzocaine can be found in

vaginal medicines that contain more than one external analgesic ingredient or in single active

ingredient hemorrhoid treatments. Benzocaine also is available in topical pain relievers that not

only relieve skin irritations, pain, and itching, but also contain other active ingredients that kill

germs and help prevent infection.
