Terbutaline is used to treat wheezing and shortness of breath from lung problems (such as asthma, chronic obstructive pulmonary disease, bronchitis and emphysema). Controlling these symptoms can decrease time lost from work or school. Terbutaline belongs to a class of drugs known as bronchodilators. It works by relaxing the muscles around the airways so that they open up and you can breathe more easily.
