text: While severe asthma has traditionally been hard to define, it’s now considered to be either asthma that requires treatment with high-dose inhaled steroids plus a second controller, systemic steroids, or both, in order to prevent asthma from becoming uncontrolled; or asthma that remains uncontrolled despite this therapy, according to the American Thoracic Society and European Respiratory Society.
