Stay well with asthma this season with these simple steps

Flu season is here

People with chronic health conditions like diabetes, cardiac or pulmonary disorders and asthma are among those at most risk from influenza. Individuals with chronic health conditions like asthma also have the highest risk for influenza-related complications.

The most effective way to prevent influenza is by getting an annual flu shot. Dr. Susan Waserman, Chair of Asthma Canada’s Medical and Scientific Committee, especially encourages people with asthma and their families to get a flu shot yearly to help prevent complications with their chronic condition.

 Flu shots are recommended annually to help reduce the frequency of asthma exacerbations, as viral and upper respiratory tract infections can both cause asthma episodes and make people with asthma more sensitive to asthma triggers.”

Oral Corticosteroids for Asthma

Most people with asthma do not use oral corticosteroids as part of their treatment plan. Oral corticosteroids can be used to treat uncontrolled asthma or in some cases, severe asthma.

Asthma Canada continues our efforts to outline and advocate regarding the concerns of overexposure to OCS. Through our Consensus Committee of healthcare professionals and patients, we’ve developed a position statement which we will leverage in our education and advocacy efforts.
