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.

Benzocaine was first synthesized in 1890 by the German chemist Eduard Ritsert (1859-1946), in the town of Eberbach and introduced to the market in 1902 under the name "Anästhesin".
1. Benzocaine is indicated to treat a variety of pain-related conditions. It may be used for:
Local anesthesia of oral and pharyngeal mucous membranes (sore throat, cold sores, mouth ulcers, toothache, sore gums, denture irritation)
Otic Pain (earache)
2. Surgical or procedural local anesthesia
3. Some glycerol-based ear medications for use in removing excess wax as well as relieving ear conditions such as otitis media and swimmers ear.
4. Some previous diet products such as Ayds.
5. Some condoms designed to prevent premature ejaculation. Benzocaine largely inhibits sensitivity on the penis, and can allow for an erection to be maintained longer (in a continuous act) by delaying ejaculation. Conversely, an erection will also fade faster if stimulus is interrupted.
6. Benzocaine mucoadhesive patches have been used in reducing orthodontic pain.
7. In Poland it is included, together with menthol and zinc oxide, in the liquid powder (not to be confused with the liquid face powder) used mainly after mosquito stings.
8. Today's ready made Pudroderm was once used there as pharmaceutical compound.
9. Benzocaine is commonly found, particularly in Britain, as an impurity in street cocaine and also as a bulking agent in "legal highs". Whilst giving a numbing effect similar 10. to cocaine on users' gums it does not actually produce the effects of cocaine. Also benzocaine can and has been mistaken for a false positive for cocaine.
11. Benzocaine was used in synthesis of Leteprinim.
