Step-by-step reduction and alternate day therapy. According to the medical education network, the method of reducing glucocorticoid 40 mg can be gradually reduced and treated every other day. Step-by-step reduction method means that after the symptoms are controlled after the disease is stabilized, the total amount of glucocorticoid is reduced by 5 mg every 1 ~ 2 weeks until the daily dosage is 20 mg, and it is reduced by 2.5 mg every 1 ~ 2 weeks. When the dosage is reduced to 10 mg every day, the reduction speed is slow. Every other day therapy is suitable for the maintenance and reduction stage after disease control. The transition from daily separate treatment to alternate day treatment is usually divided into two steps. First, change the total amount of divided treatment every day to once every morning at 8: 00, and then take the total amount for two days before 8: 00 every other morning. However, this therapy must not be rushed, and the reduction of glucocorticoid must be slower on the day of withdrawal.
