there are many otc products for warts. the one i like best is called Mediplast. it is a piece of sticky felt that has 40% salicylic acid infused. you cut the felt to the size of the wart and put it on the wart for 48 hrs. you might have to use a bandaid because it is on your finger. it is the strongest salicylic acid available and there are no other products that i know of that has this strength. be patient it takes a while but this does work well.
