If you miss a day of Ursimine, you can take it orally next. The contraceptive effect of Eusebio is mainly to inhibit ovulation or to change the thickness of the endometrium to prevent the fertilized egg from being laid and to achieve the purpose of contraception. Therefore, it is not possible to change the endometrium or inhibit ovulation by the effect of one day of the drug. However, this often leads to irregular vaginal bleeding, which will stop as long as the amount is small and the medication is continued. It is recommended to take Eusebio continuously and preferably at regular intervals for better contraceptive effect. The progestin used in Eusemide is drospirenone, which tends not to cause weight gain in patients, i.e. Eusemide has relatively few side effects.
