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.
