Benzocaine HCL works by creating a chemical barrier that halts the build-up of sodium, which
accumulates as the nerve endings are stimulated by pain. When sodium builds up, electrical
signals also build in the nerve endings. These are eventually transmitted to the brain, which
interprets the signals as pain.
Benzocaine Hcl is also called amino ethyl benzoate, a colorless or white orthorhombic needle-
like crystals or crystalline powder. Benzocaine hydrochloride salt is the hydrochloride salt form of
the local anesthetic benzocaine, with the same pharmacological effects of benzocaine and
weaker effect of anesthesia than procaine. Local absorption is slow with lasting effect. It cannot

Benzocaine is a topical analgesic (meaning it is to be used on the body surface or in the mouth
but should not be swallowed) that has a number of different uses in over-the-counter (OTC)
medicines. Depending on the dose and form, the active ingredient benzocaine can be used to
relieve throat and mouth pain; To alleviate external vaginal itching and burning; To stop pain and
itching due to hemorrhoids; Or to relieve minor skin irritations, pain, and itching. Because

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.
