For all patients, quick-relief medications include rapid-acting beta2 agonists as needed for symptoms. The intensity of treatment depends on the severity of symptoms. If rapid-acting beta2 agonists are used more than 2 days a week for symptom relief (not including use of rapid-acting beta2 agonists for prevention of exercise-induced symptoms), stepping up on treatment may need be considered.
