Just 10 days after approving a progesterone injection to prevent preterm labor, the FDA made a formal announcement warning against using terbutaline to stop preterm labor. Terbutaline is most commonly used to treat asthma, but can also be used to try to stop contractions in preterm labor.
The new FDA warning doesn't say that terbutaline should never be used in preterm labor, but does say that it is both ineffective and dangerous if used for longer than 48 hours. Doctors may still use the drug on a short term basis in moms with active contractions, but not in moms whose contractions last longer than a day or two.
