Living with Asthma

What is an exacerbation?

An exacerbation, or asthma attack, is when there’s an increase in more typical asthma symptoms such as coughing, wheezing or tightening of the chest alongside a decrease in breathing capacity. Some exacerbations can happen slowly over time, and others may develop quickly. When an exacerbation is serious, a rescue inhaler may not be sufficient, and one may use an oral steroid or visit an emergency department.
