Tocolytics are generally considered for women who are experiencing preterm labor between 24 and 34 weeks of gestation. They are particularly indicated when there is a need to delay delivery to administer corticosteroids or to transport the mother to a facility capable of managing preterm births. It is important to note that tocolytics are not typically used in cases where there are signs of intrauterine infection, significant vaginal bleeding, or severe preeclampsia.
