What is Infasurf?
Infasurf is a lung surface acting agent, or "surfactant." It helps the lungs function normally. This medicine is similar to the natural fluid in the lungs that helps maintain effective breathing.
Infasurf is used to treat or prevent respiratory distress syndrome (RDS) in a premature baby whose lungs have not fully developed.
Infasurf may also be used for other purposes not listed in this medication guide.
Your baby will receive this medication in a neonatal intensive care unit (NICU) or similar hospital setting.
Infasurf 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 Infasurf.
