Documented Uses

• Used as a local anesthetic; [Kanerva, p. 434]
• Use (kg; approx.) in Germany (2009): >1000
• Consumption (g per capita; approx.) in Germany (2009): 0.0122
• Local anesthetic commonly used as a topical pain reliever. Benzocaine is used as a key ingredient in numerous pharmecuticals: Phenazone, an anti-inflammatory; 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 acts to desensitize the penis, and theoretically allows an erection to be maintained. [Wikipedia]
