Self treatment of wart removal is generally not recommended for any kinds of warts. If you have to self treat your wart there are various kinds of over the counter treatments that you can apply. Most of these preparations would contain acids or chemicals. But it could take up to several treatments and over a period of time before you can see improvements. The treatment may cause little discomfort. It also should be kept in mind that the acids or chemicals contained in the preparation can also destroy the good skin cells surrounding the warts.
Warts such as common warts can be treated by "painting" with cantharidin by a dermatologist. Cantharidin causes a blister to form under the wart. The dermatologist then can clip away the dead part of the wart on the blister roof in a week or so.
For adults and older children a treatment called cryotherapy (freezing) is preferred. This treatment is not too painful and rarely results in scarring. Several repeated treatments at one to three weeks intervals are often necessary. Another kind of treatment called Electrosurgery (burning) is another good alternative. Laser treatment is also available and can also be used for resistant warts that have not responded to other kinds of treatments. They are move expensive and require injection of a local anesthetic to numb the area to be treated.
Another treatment is to inject each wart with an anti-cancer drug called bleomycin. The injections may be painful and can have other side effects.
