Corticosteroids use in the management of preterm labour is no more controversial, it is a well-settled corner stone in the management of preterm labour to enhance fetal lung maturity. Dexamethasone and betamethasone are used in this aspect successfully since 1972 but till now there was no settled protocol for the number of courses required to achieve optimum results. In this study, no statistical difference was found between the 2 study groups regarding patient's age, gestational age and parity. In our study, maternal adrenal suppression was seen to be more prevalent among the repeated courses group suggesting that multiple courses have profound suppressive action on hypothalarnic-piruitary-adrenal axis. So, single course is much recommended.
