Clearly, there are multiple ways to treat verruca. For this type of patient, we would try a prescription for Drysol to apply topically once daily. In many of these patients, the skin is too moist.

Vitamin A adjunct treatment is often instituted: approx 7500 IU /day for 3 weeks.

3 * x = -4 * (-x) - 15
3x-4x = -15
x = 15
