Mechanism of action

Zenchent Fe belongs to a combined oral contraceptive drug containing norethindrone and ethinyl estradiol. The contraceptive effect is conducted by suppression of ovulation, an increase in the cervical secretions’ viscosity. The change in viscosity makes it difficult for spermatozoa to penetrate the uterine cavity. It also changes the endometrium that prevents fertilized egg implantation.

The pill is washed down with water. The placebo pills (latest 7) will provoke menstruation. If it doesn’t come for several months it is necessary to address healthcare giver to exclude pregnancy.

  • oxcarbazepine, topiramate, felbamate, griseofulvin and preparations containing St. John’s wort;
  • HIV protease inhibitors (for example, ritonavir) and NNIOT (for example, nevirapine), and combinations thereof;
  • some antibiotics (for example, penicillin and tetracycline).

What if I miss a dose?

The reliability of the drug may decrease if a woman misses taking a pill containing norethindrone and ethinyl estradiol, and especially if a woman forgets taking the first pills from the blister.

If the delay in taking the drug was less than 12 hours, the contraceptive reliability is not affected. A woman should apply a tablet as soon as possible, the next tablet is applied at the time preferred.

If the missing of one or several active pills is for more than 12 hours, the contraceptive reliability may be decreased. It is necessary to use backup birth control methods.

In this case, a woman should be guided by the following 2 main regulations:

  • the drug should be taken for more than 7 days without interruptions;
  • it takes 7 days of long-lasting application of pills to maintain significant suppression of the hypothalamic-pituitary-ovarian regulation.

Zenchent Fe and pregnancy

Zenchent Fe is contraindicated during pregnancy as it may result in developmental defects of the future newborn. It is also required to withdraw the medication during breastfeeding.
