Treatment with antenatal corticosteroids (ACS) has contributed greatly to improve outcome after preterm birth. It is administered to women at risk for preterm delivery to reduce the risk of respiratory distress syndrome (RDS) and death of her preterm infant. The protective effect of ACS declines after 7-10 days. Considering that up to 50% of women remain undelivered 7-10 days after ACS administration, and in view of the neonatal benefits, repeat courses of ACS could be considered. However, unresolved concerns about safety still make such treatment
