Responses Miniziston 20 fy

Many women make the choice of this or that contraceptive means, based on recommendations of the doctor and considering the financial position. Every fourth woman gets contraceptives without recommendations, proceeding from own knowledge and responses of girlfriends that is not absolutely correct. Their appointment has to be after gynecologic and endocrinological inspection. Only the doctor is guided in difficult classification of contraceptives and can correctly choose drug.

Each tablet of the combined oral contraceptives contain estrogen and progestins. In monophase drugs which treat Miniziston 20 fy of Logest, Marvelon, Mersilon, Mikroginon and other all tablets in packaging have constant structure, so, in blood throughout all cycle identical concentration of oestrogenic and gestagenny components is created. At two-phase contraceptives the dose of a gestagenny component in the second phase of a cycle raises, and at three-phase — the dose of gestagen raises in steps in 3 stages. From the point of view of physiology of two — and the three-phase combined drugs imitate change of level of hormones at a menstrual cycle more precisely.

Responses Miniziston 20 fy are reduced to the fact that in most cases women are happy with result as they accepted drug a long time (from 2 to 5 years) and had no by-effects.

At many women by-effects were shown by increase in weight, emergence of cellulitis and "vascular asterisks" standing, the nausea expressed by drowsiness, sharp differences of mood, decrease by a libido, a hair loss, a headache. In certain cases after drug withdrawal lack of periods from 3 to 9 months was noted. Some women, imparting the bitter experience, do not advise in general to accept oral contraceptives.

This drug can be used for the emergency post-coital contraception according to the special scheme. However, gynecologists do not advise often to resort to such method of contraception as it can cause disturbances of a menstrual cycle. This method is one-time, it is possible to tell "emergency", and should not be applied during several menstrual cycles.
