Nystatin is active against a wide range of yeasts and yeast-like fungi, including Candida albicans.

Fertility, pregnancy and lactation

Pregnancy

Animal reproductive studies have not been conducted with Nystatin.

Nystatin should be prescribed during pregnancy only if the potential benefits to be derived outweigh the possible risks involved.

Breastfeeding
