Nystatin for Yeast Infections

Nystatin is a prescription medicine used to treat a variety of different fungal infections. Specifically, it is approved to treat fungal infections caused by the Candida species of fungi. Healthcare providers often prescribe it for yeast infections.
This antifungal medication is also approved for use in children. It has been shown to be safe and effective even in newborns. Nystatin is commonly used to treat diaper rashes caused by (or complicated by) a Candida yeast infection.
Nystatin works by binding to ergosterol, an important component of the fungal cell membrane. This changes the fungal cell membrane, making it more "leaky" and allowing for the leakage of important cellular contents to occur.
