Benzocaine is a lipophilic surface anesthetic that has a weaker action than several other local anesthetics such as lidocaine and prilocaine. This means that when it is applied to mucous membranes, it does not cause discomfort due to anesthetic effects. It is a lipophilic drug that is easily combined with the lipid layers of mucous membranes or skin, but it is not easily absorbed into the body and does not produce toxicity.

Benzocaine can be used as a precursor for anesthetics such as oxolane and oxolacaine; it is also used in medicine as a local anesthetic with pain-relieving and anti-itch properties. It is primarily used for anesthesia and pain relief in wounds, ulcers, mucous membranes, hemorrhoids, and pruritus. Its cream can also be used as a lubricant and analgesic for nasal and oral endoscopes. It temporarily relieves pain and itching of the skin, and is effective for mild burns, sunburns, wounds, insect bites, and acute purulent and serous otitis externa. It is also effective for toothache, pharyngitis, oral ulcers, various hemorrhoids, anal fissures, and vulvitis. It is used as a male genital desensitizer to slow down ejaculation, or as an anesthetic and lubricant for catheters and endoscope tubes.
