A member asked:
Can i inject topical benzocaine 20% myself?
A doctor has provided 1 answer
Definitely not: Dont ever do this. Benzocaine is very toxic to the heart and may cause cardiacarrest. When given topically, within reasonable limits, the concentrations in the blood stay low. Injected, however, a sudden spike in serum concentration may be harmful.
