    Applies to Newborn
    • Premature infants with respiratory distress syndrome (RDS), for rescue treatment, as the US label words the indication. The label gives no gestational age or birth weight limits in the indication text.

    Limitations
    This is the manufacturer's statement in FDA-approved labelling (openFDA copy, version 45), not a result read from a trial report: the label's clinical studies section was not read, so no numbers, comparator or follow-up are recorded. It says nothing about SUPPORT or other trials of surfactant against CPAP. The label word is rescue treatment; prophylactic use is not covered by this claim.
