Patients with polycystic ovary syndrome take Eusebio for the purpose of cyclic shedding of the endometrium to avoid endometrial lesions due to prolonged estrogen stimulation without shedding. In case of a missed dose, if the missed dose is detected after 12 hours, a replacement dose can be given. If the missed dose is missed for two days, the medication can be continued, but irregular vaginal bleeding may occur, and most of the time, the bleeding will be stopped by continuing the medication or by giving hemostatic treatment. And it is also recommended that Ursimine be given at a fixed time every day so as to avoid the possibility of missing doses. In addition, if a patient with polycystic ovary syndrome is taking Eusebio, it is generally recommended that appropriate tests be done before taking the drug, as long-term use of the drug may lead to liver and kidney function damage.
