Asthma Medicines
The way we use medicines and devices in Canada may differ from other countries. Asthma medicine advice, movies and illustrations found on this website are consistent with the latest Canadian Asthma Consensus Guidelines, based on the highest levels of scientific evidence.
Controller/Preventer
Inhaled corticosteroids are generally used daily to help heal and prevent swelling in your airways and to reduce the mucus made by the bronchial tubes. Inhaled corticosteroids are often taken even when you have no symptoms to help keep your asthma under control.
Reliever
Reliever medicine temporarily relaxes the muscles around your airways to reduce symptoms like cough, wheeze, shortness of breath, or tightness in your chest. Reliever medicine should only be used when needed.
Oral Steroids
Sometimes asthma flare-ups cannot be controlled with your usual inhaled corticosteroid medicine. During these times, you may be prescribed an add-on corticosteroid as a liquid or pill.
