Product description :
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 (e.g., products for oral ulcers of Anbesol by Pfizer, Kank-a by Blistex, and Orabase B and Orajel by Church & Dwight). It is also combined with antipyrine to form A/B Otic Drops, (Brand name Auralgan) to relieve earpain and remove earwax.Allergic reactions occur with ester local anaesthetics (like benzocaine) because of the PABA structure.Benzocaine also is a well-known cause of methemoglobinemia. Because it may be used in topical creams with a concentration as much as 20%, it is not difficult to administer a dose sufficient to cause this problem.
