Eusemide is a short-acting oral contraceptive whose active ingredient is drospirenone ethinyl estradiol, a combination treatment in combination. The active ingredients of Eusemide are the same, so whichever pill you take first is fine. However, you should try to take the pill at the same time during the process of taking Ustekin, and avoid missing doses during the process of taking the pill. If you miss a dose, you should take it in time, because if you miss a dose, it can cause breakthrough bleeding and even affect the effectiveness of contraception. Eusemide can be used for both menstrual cycle adjustment and contraception. If a woman does not plan to get pregnant in a short period of time, she can take Eusebio for effective contraception, but she should pay attention to take the pill in time during the oral contraceptive.
