Brethine subQ Warnings
Terbutaline should not be used for more than 2-3 days when treating early labor. Using terbutaline for prevention or prolonged treatment (greater than 2-3 days) of early labor has risks to the mother that are greater than any possible benefits. Serious (sometimes fatal) side effects have infrequently occurred in mothers using terbutaline during labor, such as chest pain, fast/irregular heartbeats, and trouble breathing. Tell your doctor right away should any of these side effects occur. If you are pregnant or become pregnant and are using terbutaline for another medical condition (such as asthma), talk to your doctor or pharmacist about whether terbutaline is still right for you.

Terbutaline is used to treat wheezing and shortness of breath from lung problems (e.g., asthma, chronic obstructive pulmonary disease-COPD, bronchitis, emphysema). Terbutaline is a bronchodilator (beta-2 receptor agonist) that works by opening breathing passages to make breathing easier.
