Brethine Oral Warnings
Terbutaline should not be used to prevent or treat early labor, since it has risks to the mother that are greater than the benefits. Serious (sometimes fatal) side effects have infrequently occurred in mothers taking terbutaline during labor, such as chest pain, fast/irregular heartbeats, and trouble breathing. If you are pregnant or become pregnant and are taking terbutaline for another medical condition (such as asthma), talk to your doctor or pharmacist about whether terbutaline is still right for you.
Brethine Oral Uses
Terbutaline is used to treat wheezing and shortness of breath from lung problems (e.g., asthma, chronic obstructive pulmonary disease, bronchitis and emphysema). Controlling these symptoms can decrease time lost from work or school. Terbutaline is a bronchodilator (beta-2 receptor agonist) that works by opening breathing passages to make breathing easier.How to use Brethine Oral
