The recommended starting dose for adult patients is 0.1 mg each time, twice a day, after breakfast and dinner. If the treatment effect is not obvious and the drug is well tolerated, it can be increased to 0.2 mg each time under the guidance of a doctor, but the total daily dose should not exceed 0.4 mg.

Dose adjustment strategy

In the early stage of treatment, it is recommended to maintain the starting dose for 4 weeks, and then consider adjustment after fully evaluating the efficacy.
