About Nystatin Topical Powder

What is this medication?

Nystatin topical powder is a prescription antifungal medicine used to treat various types of skin infections caused by yeast, specifically those involving Candida species. This medication works by stopping the growth of the fungus, which helps to clear the infection and relieve associated symptoms like itching, redness, or burning. It is most commonly prescribed for fungal infections occurring in moist areas of the body, such as the groin, skin folds, or between the toes.

The powder formulation is particularly beneficial for treating cutaneous yeast infections because it helps absorb excess moisture in the affected area, creating an environment that is less favorable for fungal growth. Patients typically apply the powder to the clean, dry skin area two to three times a day or as directed by a healthcare provider. It is important to complete the entire course of treatment even if symptoms improve quickly to ensure the infection is fully eradicated and does not return.
