What is Postinor and how does it work?
Now there are many means,protecting from unwanted pregnancy. But if nevertheless there was an unprotected sexual intercourse, in an emergency situation, postinor - a modern contraceptive related to the category of hormonal ones - can come to the rescue.
Postinor is used in two cases: after unprotected intercourse and with ineffective use of another method of protection from pregnancy. Postinor pack contains two white round tablets containing 750 micrograms of levonorgestrel, which is an active active ingredient of this drug. This is a very large dose of hormones, you only have to resort to taking these tablets in the most extreme cases. The active component of postinor prevents the egg from escaping from the ovary, and if it is released, it prevents its fertilization with the sperm. Postinor also helps in the case of fertilization that has already occurred: at the expense of a large dose of synthetic hormone, the introduction of a fertilized egg into the wall of the uterus is prevented. However, if the implantation of the embryo does occur, the postinor will not help, because it prevents the onset of pregnancy, but does not interrupt her. This is why the first pill of this contraceptive should be taken no later than 72 hours after having had unprotected sexual intercourse. The faster you take the pill, the better the effect will be. The second pill should be taken 12 hours later (maximum 15) after the first. There are certain contraindications to taking postinor - in particular, an allergy to the components of the medicine. You can not use an emergency contraceptive if you have had unprotected intercourse since the last menstrual period and more than 72 hours have passed after it. Do not tolerate Postinor and in case of problems with the previous menstruation: there were some deviations or delay in its start. For diseases of the small intestine, serious violations of the liver, diabetes, high blood pressure, heart disease, stroke or breast cancer in the anamnesis, before drinking postinor, it is worth consulting with the doctor. The effectiveness of postinor can be reduced by taking barbiturates and drugs intended for the treatment of epilepsy, tuberculosis, fungal infections, HIV. St. John's wort and medications on its basis also weaken the effect of postinor. If your menstruation has become weak or, conversely, too abundant, after you have taken a postinor, consult a gynecologist and go through the examination. The postinor can not be used constantly. If you often resort to emergency contraception, there will be a serious disruption of the hormonal background and, as a consequence, the menstrual cycle. In addition, taking these tablets can trigger a number of side effects: dizziness, nausea, lower abdominal pain, increased fatigue. A few days after the intake, they tend to disappear.
