Long-acting beta2-agonist bronchodilators (LABAs) are used to prevent asthma symptoms. This medicine is taken every day, even when your child is not having symptoms. It is called a controller medicine because when it’s taken regularly every day, it helps to control symptoms.
LABAs do not give quick relief of wheezing in acute asthma attacks. For acute attacks, your child needs a different type of medicine called a reliever.
Asthma symptoms are caused by 2 different problems in the airways.
Asthma symptoms often start after your child is 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 child's asthma symptoms so that your child can avoid those things or take reliever medicine before being around a trigger.
LABAs are always used with another type of controller medicine, usually an inhaled steroid. They should never be used as the only treatment for asthma. LABAs should be used for a short time only. Your child's healthcare provider may stop the LABA once other types of daily medicines are controlling asthma symptoms.
Asthma symptoms come and go throughout the day or week and get better with medicine.
LABAs relax the muscles in the airways and keep the muscles from getting too tight. When the airway muscles are more relaxed and less tight, your child will have fewer symptoms and be able to breathe better. Other medicines used with LABAs can lessen swelling and inflammation.
The medicine can be taken in different ways. For example:
If you have any questions, ask your healthcare provider or pharmacist for more information. Be sure to keep all appointments for provider visits or tests.
