The intrauterine device "Mirena". Instructions

There is a long-established statement that children are flowers of our lives. This is true, but only if they are desired. Unplanned pregnancy, about which women say "it happened", hardly gives them a special joy. At the same time, some of them remain pregnant and give birth to an unexpected child, while others decide on abortion. Of course, everyone has their own independent opinion on this matter, but still, probably, abortion is not an act that can be proud of. Many gynecologists ask with perplexity why women are taking such a step? Is not it better to think about the consequences in advance and just warn the pregnancy? Indeed, at the moment there are many different methods of contraception. Each female representative can choose for herself what is best for her, and in this article I would like to elaborate on intrauterine systems.

One of the most common and widely known intrauterine systems is the Mirena spiral. The instruction attached to this spiral indicates the content of the hormone in it. Therefore, it can be used not only as a means of preventing unwanted pregnancies, but also in some other cases. Thus, since the spiral "Mirena" is hormonal, it can be prescribed as a substitution therapy for estrogen, for the treatment of menorrhagia, and also for protecting against too rapid growth of the inner shell of the uterus.

All intra-uterine systems guarantee 98% reliability. The contraceptive spiral "Mirena" is also very effective, convenient and long-term contraceptive. After its installation, you can forget about the methods of protection for the next 5 years. In addition, this system is made in a T-shape, which helps it to more accurately fit the shape of the uterus.

Let's try to figure out how the "Mirena" spiral works. The instructions for use describe in detail the action of levonorgestrel contained in the core of the Mirena. The container containing levonorgestrel is covered with a membrane. Through it occurs its controlled continuous diffusion. Levonorgestrel is released with a constant constant rate in very small amounts, its daily release is 20 μg.

Spiral "Mirena" does not allow the occurrence of pregnancy, it controls the development of the uterine membrane and prevents the penetration of sperm into the uterus. Levonorgestrel, which enters the uterine cavity, locally affects the endothermia, preventing it from making any polymorphic changes and reducing its implant function. Thus, the endothermia does not reach the maturity that is necessary for the onset of pregnancy. Levonorgestrel also has a small systemic effect, which is manifested in the inhibition of ovulation in several cycles.

Spiral "Mirena" helps to reduce the volume of intensive menstrual bleeding immediately after 2-3 months of use. The volume of menstrual blood loss is reduced by approximately 88%. Some women report a complete cessation of menstrual bleeding. And this, in turn, reduces the risk of iron deficiency anemia. Also, Mirena is able to reduce premenstrual and menstrual pain.

However, there are some contraindications in which the Mirena spiral can not be used. Instructions for its use include the following states:

• The presence of cancer of the uterus or cervix, and the suspicion of it;
• Pregnancy or the assumption of its presence;
• Abnormalities of the uterus or cervix;
• Cervicitis;
• mammary cancer;
• Endometritis postpartum ;
• Infection of the uterus due to abortion;
• Urinary tract infections;
• Intolerance of the components of the spiral.

It is necessary to say that acquiring the "Mirena" spiral instruction is needed for you only for acquaintance, and all the other advice on its installation you can get only after a gynecological examination by a doctor.
