Considerations for taking tocolytic medications

The factors your doctor or nurse-midwife will consider before offering tocolytic treatment for preterm labor include:1

  • Your due date. If you are close to your due date, delaying the birth may not be necessary. (Most health professionals will not consider using a tocolytic after 34 weeks of pregnancy.)
  • How far you have progressed in labor.
  • Whether you have an infection in your uterus. If you do have a uterine infection, tocolytics should not be used.
  • Whether your amniotic sac has broken (premature rupture of membranes, or PROM).
  • Your health. If you have high blood pressure or heart or kidney problems, tocolytic medications may be dangerous.
  • The health of your fetus. Tocolytics are not used if a fetus is in distress or has died before birth.
  • Your fetus's lungs. A tocolytic may hold off the birth long enough for steroid medicine to help your fetus's lungs develop.
