The use of terbutaline for the treatment of preterm labor is an unlabeled use of the medicine. Terbutaline has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of asthma and other breathing conditions, but it is also widely used to treat preterm labor.
Terbutaline should not be used for longer than 72 hours for the treatment of preterm labor.
Terbutaline can relax smooth muscles, like the uterus. It also affects the smooth muscles of the blood vessels and the small airways of the lungs.

Side effects are common with terbutaline use and may affect both the mother and fetus.
Common side effects of this medicine include:
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
If terbutaline treatment is effective, its effect typically lasts no more than 48 hours. Long-term treatment is not advised (based on the risk of serious side effects), nor is it effective.1
