How does this medication work? What will it do for me?
Nystatin belongs to the group of medications known as antifungals. Nystatin oral medications in liquid form are most often used to treat fungal infections in the mouth.
The liquid and tablets are used to treat a fungal infection of the intestine known as candidiasis. This occurs when the fungus known as Candida albicans overgrows in the intestine as a result of antibiotic or corticosteroid use. The medication may also be used to prevent fungal infections.
The powder can be used to make an oral liquid or added to creams or ointments. The skin cream and ointment are used to treat fungal skin infections. The vaginal cream is used to treat vaginal infections caused by Candida albicans.

How should I use this medication?
Oral suspension: The recommended dose of nystatin oral suspension for infants is 200,000 units (2 mL of suspension) 4 times daily, dropped onto the tongue and then swallowed. The recommended dose for children is 400,000 to 600,000 units (4 mL to 6 mL of suspension) 4 times daily. For adults, the usual dose is 400,000 to 600,000 units 4 times daily.
For young infants and children, the solution may be mixed with milk, lukewarm formula, jam, or peanut butter.
Shake the bottle before use. Use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.
Skin cream or ointment: Apply cream or ointment liberally to affected areas twice daily or as prescribed by your doctor. Severe fungal infections may require the use of both oral and topical nystatin.
Vaginal cream: The usual dose is one full applicator (5 grams) inserted into the vagina daily at bedtime. For severe infections, a dose of one applicator every 12 hours may be given. Usually, treatment is given for 2 weeks. Treatment should be continued during menstruation.
To prevent a relapse, treatment should be continued for at least 48 hours after the symptoms go away, regardless of dosage form.
