1.Inhaled glucocorticosteroids at medium and high doses (e.g., greater than 250 micrograms of fluticasone per day) alone, 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 stifled awakenings, no need for emergency relief medication and no activity limitation for 3 consecutive months); 2.Inhaled glucocorticosteroids at low doses (e.g., less than 250 micrograms of fluticasone per day) alone can achieve 3. If inhaled glucocorticosteroids and long-acting β2 agonists are used in combination, the dose of inhaled glucocorticosteroids should be reduced by about 50% until a low dose of inhaled glucocorticosteroids (e.g., 125 micrograms of fluticasone per day) is reached before considering stopping the use of long-acting β2 agonists and switching to low-dose inhaled glucocorticosteroid therapy alone; 4. If the child’s asthma can be maintained under control with the lowest dose of inhaled glucocorticoids (e.g., less than 50 micrograms of fluticasone per day) and no recurrence of symptoms within 1 year, discontinuation may be considered.
