Treatment Options for Warts

Treatment Options for Warts
A wart is generally a small, rough growth on the skin that can resemble a cauliflower or a solid blister. There are as many as 10 varieties of warts, caused by one of the many types of human papillomavirus. Warts are contagious. The virus love warm and moist environments, and can be transferred by sharing towels, slippers, and make-up sponges for example. You can also spread the warts on your body by rubbing a towel on the infected site and then rubbing the same towel on your entire body.

Most warts are easily treatable but they can regrow if not thoroughly removed. Very often, creams, gels or pads with high level of salicylic acid can be sufficient to treat warts. Salicylic acid is applied to the surface of the wart on a regular basis. A few weeks of regular application will be sufficient but there are some warts that may take up to a year to treat. You will need to use emery board or pumice stone to clear the dead skin the wart leaves behind. The average cure rate is 75%. A less popular product is silver nitrate, which can cause staining of skin and clothing. Occasionally, pigmented scars may develop. Silver nitrate method has a cure rate of 43%.

There are prescription treatments available. Imiquimod cream works by encouraging your body’s immune system to work against the wart. It is approved for use in genital warts by US FDA but is very expensive. If you have genital warts, have a check up with a doctor. Dinitrocholorobenzene (DNCB) is a much stronger option to salicylic acid, with a high cure rate of 80%. However, DNCB is a known mutagen, able to cause genetic mutations. Only a doctor should apply it.

Some individuals will want a more aggressive approach, which is where procedures can be used in removing warts. Cryosurgery can be used to freeze off a wart by exposing it to liquid nitrogen.Complications include blistering of normal skin if excess freezing is not controlled. Laser treatment - often with a pulse dye laser or carbon dioxide (CO₂) laser can be quite effective but can also be very costly. Duct tape occlusion therapy is an option that remains controversial at the moment with regards to its effectiveness.

Electrocauterization is a popular procedure offered at SkinStation. Pinpoint and complete removal of warts is accomplished with virtually no pain and relatively low cost. Topical anesthesia is applied which requires 30 minutes to numb the skin. Then, a needle-like tip heated by electric current is applied over the wart. The actual procedure will take from 15 to 60 minutes depending on the number of warts to be treated. Scabs will form over the warts treated. The scabs should not be forced out to avoid scarring. They will drop off in 5 to 7 days, leaving small reddish marks that will disappear in a week or so.

With so many options available, the choice is yours. You may even opt not to do anything and wait for the warts to simply disappear. However, if you have the persistent kind, it’s best that you have them treated lest the warts multiply and become ugly and bothersome skin appendages.
