Terbutaline has also caused serious side effects in newborns whose mothers took the medication to stop or prevent labor.

WHY is this medicine prescribed?

Terbutaline is used to prevent and treat wheezing, shortness of breath, and chest tightness caused by asthma, chronic bronchitis, and emphysema. Terbutaline is in a class of medications called beta agonists. It works by relaxing and opening the airways, making it easier to breathe.

Are there OTHER USES for this medicine?

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

HOW should this medicine be used?

Terbutaline comes as a tablet to take by mouth. The tablets are usually taken three times a day, once every six hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take terbutaline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Each dose of terbutaline should control your symptoms for at least 6 hours after you take it. If you find that your symptoms return before it is time for your next dose, that terbutaline does not control your symptoms as well as it did at the beginning of your treatment, or that your symptoms are getting worse, call your doctor. These may be signs that your condition is worsening.

Terbutaline may control your symptoms but will not cure your condition. Continue to use terbutaline even if you feel well. Do not stop taking terbutaline without talking to your doctor.

What should I know about STORAGE and DISPOSAL of this medication?

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
