The U.S. Food and Drug Administration are considering approving a drug to help reduce the number of premature babies. If approved, Gestiva would be the only drug available to help mothers carry their babies to term. It too have certain potential drawbacks, for instance, it does not appear to help prevent the earliest preterm births, which most often result in complications and death. The drug may also increase the rate of miscarriage and stillbirths. Thus, doctors are taking a cautious approach to a wider and easier availability for the drug.
