If you take Eusebio for contraception or to adjust your menstrual cycle, starting to take it during non-menstrual periods is not effective and may affect the hormone level in your body, leading to irregular vaginal bleeding due to ovarian dysfunction and unplanned pregnancy due to contraceptive failure. If you need to take Eusebio to stop bleeding due to anovulatory hemorrhage, after taking Eusebio during non-menstrual period, it still has obvious effect of stopping bleeding, but you need to increase the dose of Eusebio. It is often necessary to take one tablet three times a day for three consecutive days to significantly reduce the amount of blood, and if there is no significant reduction, the organic lesion should be ruled out again. Therefore, women who want to take Eusebio to regulate their menstrual cycle or take Eusebio for regular contraception are advised to start taking it within the second to fifth day of menstruation, once a day, one tablet each time, and not to miss any dose during the dosing period, and to take it at the same time.
