Topical nystatin is used to treat some types of fungus infections of the skin.
Nystatin is available in the U.S. only with your doctor's prescription. In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. Also tell your health care professional if you are allergic to any other substances, such as preservatives or dyes. It is not known whether nystatin passes into breast milk.
