Terbutaline is prescribed as a rescue treatment for sudden breathlessness or wheezing in people with ASTHMA or COPD. It is referred to as a ‘reliever’ because it relieves the symptoms of breathlessness.
Terbutaline belongs to a group of medicines called bronchodilators because it widens (dilates) your airways. It works by opening up the air passages in your lungs so that air can flow into your lungs more freely. This helps to ease symptoms such as coughing, wheezing and feeling breathless. It starts to work within a few minutes and the effect will last up to six hours.
