Bronchodilator: Short-Acting Beta2-Agonist (SABA)

What is this medicine used for?

Short-acting beta 2-agonist bronchodilators (SABAs) are also called quick-relief, reliever, or rescue medicines. These medicines are used as needed to treat sudden breathing problems caused by asthma, chronic bronchitis, or emphysema. (Chronic bronchitis and emphysema are also called chronic obstructive pulmonary disease, or COPD.) You should learn to recognize the symptoms of an attack and take this medicine as soon as symptoms start.

This medicine is not used on a regular, daily basis to prevent symptoms. You may need a different type of medicine called a controller to keep from having attacks of symptoms. Controller medicines are taken on a regular schedule to prevent asthma symptoms.

If you have asthma or COPD, you may have symptoms like coughing, wheezing, and shortness of breath. Your symptoms are caused by 2 different problems in the airways.

• One problem is that the muscles in the airways tighten up, which causes the feeling of chest tightness and wheezing.
• The other problem is swelling, irritation, and too much mucus in the airways.

Asthma symptoms often start after you are exposed to a trigger. Asthma triggers can include pollen, animals, mold, colds, exercise, cold air, and air pollutants. It’s important to know what things trigger your asthma symptoms so that you can try to avoid those things or take your reliever medicine before being around a trigger.

Asthma symptoms come and go throughout the day or week and get better with medicine. If you have COPD, your symptoms usually get worse over time and never go away completely.

How does it work?

SABAs work fast to relax the muscles of the airways and to keep the muscles from getting too tight. When the airway muscles are more relaxed and less tight, you will have fewer symptoms and be able to breathe better.

The medicine can be taken in different ways. For example:

• A hand-held device, such as a metered-dose inhaler (MDI) or a dry powder inhaler, is small and easy to carry with you. Inhalers help send the medicine directly to your lungs as you take a deep breath. Some MDI medicines may need a spacer. A spacer is a small tube or bag that holds the medicine while you breathe it into your lungs.
• A nebulizer is a machine that you can use at home. Medicine is mixed with liquid and the machine forms a mist. You breathe in the mist to help get the medicine into your lungs.

What else do I need to know about this medicine?

• Try to get all of your prescriptions filled at the same place. Your pharmacist can help make sure that all of your medicines are safe to take together.
