Adults and Children: Dosage ranges of 1-6 mL (100,000-600,000 units nystatin) 4 times daily have been used.
Infants: Recommended Dose: 1 or 2 mL (100,000-200,000 units nystatin) 4 times daily.
Limited clinical studies in premature and low birth weight infants indicated that 1 mL administered 4 times daily is effective.
The dosage regimen for nystatin oral suspension should be continued for at least 48 hrs after symptoms have disappeared. If signs and symptoms worsen or persist (>14 days of treatment), the patient should be re-evaluated and alternate therapy considered.
Administration: The suspension should be retained in the mouth for as long as possible (eg, several minutes) before swallowing. In infants and young children, apply ½ of dose in each side of mouth.
