How does it work?
This birth control contraceptive contributes to a decrease in serum concentrations of follicle-stimulating and luteinizing hormone. It also suppresses ovulation, increases the viscosity of the cervical secretions. It is well-known by the difficulty of sperm penetration through the fallopian tube. Mircette causes endometrium rearrangement, which makes it difficult to implant the fertilized egg.
In addition to contraceptive properties, this combined oral contraceptive has a number of effects that can be taken into account when selecting a contraceptive method. Menstruation becomes more regular, less painful and less abundant. These circumstances lead to a decrease in the frequency of concomitant iron deficiency anemia.

Preparations inducing liver enzymes, such as hydantoin, barbiturates, primidone, carbamazepine, rifampicin, oxcarbazepine, topiramate, felbamate, griseofulvin, and St. John’s wort-containing drugs reduce the effectiveness of oral contraceptives provoking the risk of bleeding. They increase the risk of intermenstrual bleeding. The maximum level of induction is usually achieved not earlier than 2-3 weeks but can last up to 4 weeks after drug discontinuation.
Ampicillin, tetracycline – reduce effectiveness (interaction mechanism is not confirmed).
Katie Lees: “I take Mercette 28. Everything is ok. No weight gain, no hair loss, no health harms. But it is necessary to visit the gynecologist for doing the tests for hormones and pick the birth control up.”
Keira Baker: “Those who say that they didn’t pick up suitable birth control, in most cases, choose them themselves and then complain about what horrible pills they are. Doctors have repeatedly told women only they should decide what kind of contraceptive means to take. I have been taking Mircette for almost 8 years with breaks, including during pregnancy. I am satisfied, children were born in the family at the appropriate time and I did not have to make abortion as many people do. Mircette never failed me, my weight is normal, I even lost a little after I started taking it. The main thing is not to prescribe it to yourself, consult your doctor. All drugs have contraindications and side effects, remember this.”
