How are warts treated?...

Prescription remedies

Treatments that may be prescribed by a medical professional include:

• Imiquimod, a topical cream that helps the body's immune system fight the wart virus by encouraging interferon production
• Candida injections at the site of the wart, which also stimulate the body's immune system
• Cryosurgery, which involves freezing the wart, after which the wart and surrounding dead skin falls off by itself.
• Cryosurgery followed by surgically removing the infected spot.
• Treatment with chemical compounds, containing salicylic acid, blistering agents, immune system modifiers, or Formaldehyde
• Laser treatment

None of these treatments are very effective on single uses; the wart often returns after the skin has healed from the treatment, but repeated treatment should get rid of the wart permanently. As they disappear after a few months and maximally a few years, treatment is necessary only if the lesions are painful or are a cosmetic problem.

Over-the-counter remedies

There are also several over-the-counter options. The most common ones involve salicylic acid. These products are readily available at most drugstores and supermarkets.

There are typically two types of products: adhesive pads treated with salicylic acid, or a bottle of concentrated salicylic acid.

Removing a wart with this method requires a strict regimen of cleaning the area, applying the salicylic acid, and removing the dead skin with a pumice stone or emery board. It may take up to 12 weeks to remove a stubborn wart.

Another over-the-counter product that can aid in wart removal is silver nitrate in the form of a Caustic Pencil, which is also available at drug stores. This method generally takes three to six daily treatments to be effective. The instructions must be followed to minimize staining of skin and clothing.

Over-the-counter cryosurgery kits are also available.

Like prescription treatments, over-the-counter treatments usually require multiple applications.

It is worth bearing in mind that these treatments are capable of destroying healthy skin as well as warts, so caution must be exercised by those attempting them without medical supervision.

Household remedies:

Duct tape occlusion therapy involves placing a piece of duct tape (or medical tape) over the affected area for a week at a time. The procedure is otherwise identical to that of using salicylic acid adhesive pads. A study found that the duct tape method was 85% effective, compared to a 60% success rate in the study's cryotherapy group.

Other household remedies include the application of common household things, such as banana skin, vinegar, hot water and washing liquid, aerosol sprays, or unskinned potatoes, to the affected area.

Accounts vary in regards to how long they must be applied in each session and how long they take to work.

Some household remedies are potentially dangerous. These include attempts to cut or burn away the warts. Incense is sometimes used in Asian countries to burn warts. These methods are very painful, and can lead to infection and/or permanent scarring.
