The management of very mild and mild asthma in preschoolers, children, and adolescents

This practice point summarizes recommendations from the Canadian Thoracic Society's 2021 "Guideline update: Diagnosis and management of asthma in preschoolers, children, and adults." New recommendations include: a decrease in the frequency of daytime symptoms and reliever use to <= 2 per week in the asthma control criteria; assessing for risk of asthma exacerbation; not using as-needed short-acting beta-agonists alone in patients at higher risk for exacerbation; and the option of as-needed budesonide/formoterol (bud/form) in those >= 12 years old if they are unable to take daily inhaled corticosteroids despite extensive asthma education and support. The preference for daily inhaled corticosteroids to manage mild asthma in children, and the recommendation against intermittent short courses of inhaled corticosteroids, are unchanged.
