Benzocaine is a local anesthetic commonly used as a topical pain reliever or in cough drops. It is the
active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is also
combined with antipyrine to form A/B otic drops to relieve ear pain and remove earwax.
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)
Surgical or procedural local anesthesia
And also Benzocaine is used as a key ingredient in numerous pharmaceuticals:
Some glycerol-based ear medications for use in removing excess wax as well as relieving ear conditions
such as otitis media and swimmers ear.
Some previous diet products such as Ayds.
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
Benzocaine mucoadhesive patches have been used in reducing orthodontic pain.
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. Today's ready made Pudroderm was once used there as pharmaceutical compound.
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 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.
Benzocaine was used in synthesis of Leteprinim.
