Important warnings
This medicine can cause some serious health issues
Your baby will receive this medication in a neonatal intensive care unit (NICU) or similar hospital setting.
Calfactant is given directly into the baby's lungs through a breathing tube that is also connected to a ventilator (a machine that moves air in and out of the lungs to help your baby breathe easier and get enough oxygen).
Your baby will remain under constant supervision during treatment with calfactant.
Calfactant causes few side effects. There is a possibility that the baby will have breathing difficulties during the calfactant (the active ingredient contained in Infasurf) treatment, and these problems may require further treatment by health care professionals. Your baby will remain under constant supervision during treatment with calfactant.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.
