1.For those who use medium and high doses of inhaled glucocorticoids alone (e.g., greater than 250 micrograms of fluticasone per day), try to reduce the dose by 50% after achieving and maintaining asthma control for 3 months (i.e., no daytime symptoms, no nocturnal symptoms or awakening, no need for emergency relief medication and no activity limitation for 3 consecutive months); 2.For those who use low doses of inhaled glucocorticoids alone (e.g., less than 250 micrograms of fluticasone per day) and can achieve 3. For combined use of inhaled glucocorticoids and long-acting β2 agonists, first reduce the inhaled glucocorticoids by about 50% until a low dose of inhaled glucocorticoids (e.g., 125 micrograms of fluticasone per day) is reached before considering discontinuing long-acting β2 agonists and switching to low-dose inhaled glucocorticoid therapy alone; 4. 4. If asthma control is maintained with the lowest dose of inhaled glucocorticoids (e.g., less than 50 micrograms of fluticasone per day) and there is no recurrence of symptoms within 1 year, discontinuation of the drug may be considered.
