Caution should always be observed in using these medications and you should follow the instructions closely. The most common problem in having the patient use over the counter medication, is over treatment. This can cause more damage and make the lesion or lesions more resistant to any form of treatment. If any adverse reaction should occur, consult your podiatrist. Warts thrive in a moist, dark environment.
Medication is used to dissolve the core of the wart or to inhibit their growth.
With acid medication, the wart is broken down by applying an acidic solution. Blister-forming solutions may also be used. The treatment may need to be repeated over several weeks. Another form of treatment involves drying agents, similar to formaldehyde, which dry the skin and decreases the size of some large lesions as well as removing smaller warts. A local anesthetic is often used with this procedure to make it more comfortable.
