Zovia 1 / 35E is an oral contraceptive containing female hormones known as ethinyl estradiol and ethynodiol diacetate. The drug is used to prevent pregnancy.
Indications for use
Mechanism of action
Ethinyl estradiol and ethynodiol have a depressing effect on the gonadotropic (regulating activity of the gonads) function of the pituitary gland (an internal secretion gland located in the brain), which causes inhibition of ovulation (the exit of a mature egg from the ovary), and also improves the functional state of the endometrium (the inner layer of the uterus).

Each Zovia 1 / 35E pack contains 21 active tablets and 7 inert tablets (without hormones).
Take 1 tablet per day for 28 days in a row, without intervals. On day 22-28, menstrual bleeding occurs. You can take the pills on the “Sunday” schedule and the “fifth-day” schedule. ”

What if I miss a pill?
The likelihood of an unwanted pregnancy is minimal if you missed 1 active tablet but the effectiveness of the drug may decrease. If you forget to take the tablet at your usual time, you should take 2 tablets the next day. If you missed 2 tablets for 2 consecutive days, you should take 2 tablets per day for 2 days. Then, continue taking the pills as usual and use additional non-hormonal contraceptive drugs (barrier methods: condom, chemical spermicides) for the next 14 days or until another menstrual bleeding occurs. If you missed an inert tablet, just throw it away.
Vomiting or diarrhea can lead to the withdrawal of ethinyl estradiol and ethynodiol diacetate from the body, so if you have gastrointestinal disorders 1-4 hours after taking an active tablet, you should take an additional pill. If these symptoms persist for a longer time, you should temporarily use other birth control methods.
