Nystatin Dosage

The recommended dosage of nystatin for treating yeast diaper infections or other fungal skin reactions is a liberal amount of the ointment, cream, or powder applied to the affected area twice a day. For oral nystatin products, dosing is determined by your age and the specific condition being treated (oral thrush, digestive infections, etc.).

  • Your age

Diaper Rash or Other Skin Infections

For very moist areas, nystatin powder may be more appropriate. This product is usually applied two or three times daily until healing is complete. If you are treating a fungal infection of the feet, it is usually recommended that the feet and shoes be dusted with the powder.
