The effectiveness of hydroxyprogesterone caproate injection is based on improvement in the proportion of women who delivered < 37 weeks of gestation. There are no controlled trials demonstrating a direct clinical benefit, such as improvement in neonatal mortality and morbidity. Limitation of use : While there are many risk factors for preterm birth, safety and efficacy of hydroxyprogesterone caproate injection has been demonstrated only in women with a prior spontaneous singleton preterm birth. It is not intended for use in women with multiple gestations or other risk factors for preterm birth.
