Controller/Preventer Medicine

Controller/preventer medicine must be used regularly to help heal and prevent swelling in the airways. These medicines are often taken even when you have no symptoms, and help keep your asthma under control.

Remember to check with your local pharmacy on how to dispose of unwanted/expired medication, including asthma devices.

Why should my child take asthma medicine?

Corticosteroids

Inhaled corticosteroids are the most commonly used controller/preventer medicines to keep asthma under good control. Corticosteroids have been used for many years to treat asthma and are very safe. These are not the same type of steroids that some athletes use to build muscle and they are not addictive.

When regular use of preventer medicine does not control your asthma, your doctor may add a second type of preventer/controller medicine to improve the effect of the first medicine.

Experts Talk About Inhaled Corticosteroids

Leukotriene Receptor Antagonists

Leukotriene Receptor Antagonists (LTRAs) block the release of Leukotrienes, which cause swelling in the airways of the lungs. These chewable pills can be taken in addition to an inhaled corticosteroid. Some people with very mild asthma may be able to take only the pill to control their asthma symptoms, however, Canadian Asthma Guidelines suggest that almost all patients should be started on inhaled corticosteroids first.

Device Drug Name
Tablet Singulair, Montelukast

Long Acting Beta Agonists

Long Acting Beta Agonists (LABAs) relax the muscles surrounding the airways in the lungs for about 12 hours and may be used when the regular use of an inhaled corticosteroid alone does not control your asthma. Your doctor may add a LABA to enhance the effectiveness of the corticosteroid. LABAs should always be used in addition to an inhaled corticosteroid medicine and should be taken regularly, like inhaled corticosteroids. LABAs do not replace reliever medicine in an emergency.

Device Drug Name
Turbuhaler Oxeze

Combination Medicine

Combination Medicines are convenient if your child needs to take both an inhaled corticosteroid and a LABA medicine, because they can take both medicines, in a single device.

Device Drug Name
Metered Dose Inhaler (MDI) Advair, Zenhale
