The intrauterine device 'Mirena'. Reviews and contraindications

Each woman of childbearing age thinks about how best to protect herself from unwanted pregnancy. As you know, there are many methods, but those that give a large percentage of protection are units. Today we are talking about the "Mirena" spiral. The reviews allow us to draw conclusions about it as a reliable means of contraception, which delivers the least discomfort to both sexual partners. The spiral system resembles the letter "T" 32 mm long. The vertical rod is enclosed in a container in the form of a cylinder, in which there are 52 mg of the drug "Levonorgestrel". The system itself is made of polyethylene. The content of the spiral is continuously released from the container and enters the female body in an amount not exceeding 20 micrograms per day. Thus, having established a spiral once, a woman can not worry about the occurrence of an unwanted pregnancy during the shelf life of the spiral - 5 years.

How it works?

Levonorgestrel suppresses the functional activity of the endometrium, creating obstacles for the successful implantation of the ovum, changes the properties of cervical mucus, which becomes too viscous and creates a barrier to penetration of spermatozoa, resulting in decreased sperm motility, so fertilization does not occur. And all this is due to the Mirena system installed in the body. The experts' feedback confirms that the contraceptive effect of using this spiral is comparable with those that can be achieved with voluntary surgical sterilization.

This method is most in demand for many women, since it is safe, the drug is reversible, and you do not need to take contraceptives in the form of tablets every day, and the main advantage is the presence of a therapeutic effect in case a woman suffers from heavy menstrual bleeding. Even with a small myoma, this spiral can be used. To introduce her into the body is recommended on the first or seventh days of the menstrual cycle, and women with amenorrhea - on any day.

However, there are side effects that are revealed in some patients during the use of the Mirena spiral. Reviews indicate that the first 4 months of the active substance in the reservoir can affect the general condition of the woman, causing headaches, a sharp change of mood, acne, mastalgia, nausea. In addition, as statistics show, 12% of patients had functional ovarian cysts, which later regressed independently.

There may be irregularities in the menstrual cycle after the installation of the Mirena system. The reviews confirm that in most cases these disorders occur very rarely, in the first six months, and are associated with the appearance of intermenstrual uterine bleeding, meager menstruation, amenorrhoea, etc. In most cases, these symptoms subsequently pass.

Spiral "Mirena", contraindications

Situations in which the device is contraindicated include acute thrombophlebitis, hepatitis, breast cancer, cirrhosis and other liver tumors, ischemic heart disease, and general contraindications for the installation of intrauterine spirals. There are, however, some states in which a spiral can be used, since the benefit from its application exceeds the possible risk. These include hypertension, vascular disease, headaches, diseases of the cardiovascular system (or a predisposition to them).
