Nystatin is used to treat fungal infections of the skin, mouth, and intestinal tract. Fungal medicines will not work for colds, flu, or other viral infections.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Nystatin comes as a tablet, capsule, and a liquid to take by mouth; a soft lozenge (pastille) to be dissolved slowly in the mouth; a tablet and vaginalcream to be inserted into the vaginaa; and in powder, ointment, and cream to be applied to the skin.

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use nystatin exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.Nystatin liquid usually is used three to five times a day for mouth infections and three times a day for intestinal infections. Shake the bottle well before each use to mix the medication evenly. If you are using liquid nystatin for a mouth infection, place half of the dose in each side of the mouth and hold it there or swish it throughout the mouth for several minutes before swallowing. Good oral hygiene, including proper care of dentures, is important for the cure of mouth infections.
