Infasurf Side Effects Center
Infasurf (calfactant) is used to treat or prevent respiratory distress syndrome (RDS) in a premature baby whose lungs have not fully developed. It is a lung surface acting agent, or "surfactant." It helps the lungs function normally. Infasurf causes few side effects. There is a possibility the baby will have breathing difficulties during treatment, and these problems may require further treatment.
Each dose of Infasurf is 3 mL/kg body weight at birth. Infasurf has been administered every 12 hours for a total of up to 3 doses. Drug interactions between Infasurf and other medications are not expected to occur. Your baby's caregivers will manage and monitor all medications given to your baby during treatment in the NICU. Because this drug is intended for premature babies, it is unlikely to be used by pregnant or breastfeeding women. Our Infasurf (calfactant) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
