Antenatal corticosteroid therapy: benefits and risks

Antenatal glucocorticoid therapy remains one the most striking successes in perinatal management of complicated pregnancies leading to premature birth. All women at risk of preterm delivery before 34 weeks gestation should be treated, given the anti‐inflammatory and maturative properties of fluorocorticoids. Betamethasone is preferred to dexamethasone and no more than two courses, two weeks apart, should be given, until the evidence from further controlled trials on repeated doses becomes available.
