Anal warts can be treated with medications, if they occur singly, isolated and relatively small. Drugs play a role in corroding the warts, such as onychotoxin, trichloroacetic acid or euthyroxin and other drugs. However, the use of drugs must be the normal skin mucous membrane protection, can be used to medical tape around the warts, only the warts exposed, and then use. Because chemical corrosive drugs are liquid, if not to protect the normal mucous membrane, liquid corrosive agent will be the normal skin mucous membrane corrosion, corrosion of the skin mucous membrane after the breakage of the virus will be re-formed in the broken mucous membrane on the formation of artificial planting. If the creamy drug does not have liquidity, simply corrode the warts can also be used.
