  1. Mirena To a woman of childbearing age, the intrauterine device MIRENA as a contraceptive can be placed in the uterine cavity no later than 7 days fromThe beginning of the menstrual cycle.
  2. If the introduction of the spiral is supposed to occur at a later date, the doctor must first be convinced of the absence of pregnancy.
  3. After birth, the contraceptive in question is not established before 6 weeks later - this is the time period required for complete restoration of the uterus.
  4. If in the postpartum period a woman has a decrease in the rate of contraction of the uterus, the timing of the introduction of the Mirena spiral is postponed to a later time.
  5. After an artificial or spontaneous abortion that occurred in the first and / or second trimester of pregnancy, the Mirena intrauterine device should be installed only after 7 days.In this situation, the doctor must be sure that there are no signs of infection in a woman.

Note: if a woman complains of very severe pain during the installation of the contraceptive in question, or a bleeding has begun, the gynecologist should perform an ultrasound and physical examination to exclude uterine perforation( mechanical damage).

The process of removing the intrauterine device Mirena

If a woman's menstrual cycle is regular, then Mirena can be removed on any day of menstruation after the expiration of her period.If a woman needs further contraception, then the doctor can install a new spiral on the same day.

If the spiral is not extracted during menstruation, then one week before this manipulation a woman should use additional contraceptive devices .The same rule applies if the patient is diagnosed with amenorrhea.

After the extraction of the intrauterine contraceptive, the physician must make sure that the spiral is intact.Often during the procedure under consideration, the hormone-elastomeric core slips to the horizontal "shoulders" of the T-shaped body.After the integrity of the helix is ​​confirmed, no additional examinations and interventions are required.

Note: the installation of a new spiral is possible immediately after the removal of the old one because the full safety of the use of two or more intrauterine systems in a row has been proven.No changes in the health of women are noted .

Intrauterine device MIRENA during pregnancy and during lactation

Mirena-bc No hormonal agents, including those considered, can be used during pregnancy.If pregnancy occurs during the application of Mirena, then it must be extracted, since the risk of spontaneous abortion or premature birth is significantly increased for a woman.

It is necessary to remove the contraceptive in pregnancy very carefully, but if this is not possible, the doctor will raise the issue of the artificial termination of pregnancy.A woman may refuse to have an abortion, but in this case she should be informed about the risks and possible consequences of premature births for the child.The patient herself will have to carefully monitor her own well-being and when there are colicky abdominal pains, fever should immediately seek qualified medical help.

As for the application of Mirena to a woman who is breastfeeding, doctors are unequivocal in the opinion - if the spiral is established 6 weeks after birth, then there will be no impact on the growth and development of the child .The hormone that enters the blood of the nursing mother does not affect the quality and quantity of breast milk.

Possible complications when using Mirena

In general, the use of the intrauterine contraceptive in question rarely leads to complications, and if any unusual symptoms appear, the woman should immediately seek qualified medical care.Nevertheless, problems can arise.

Expulsion - prolapse of the intrauterine device

The intrauterine device can partially or completely fall out of the uterine cavity, with the highest risk of such a phenomenon occurring in nulliparous women in the first few months after installation of the drug.It is extremely rare for the system to be rejected at a later date.

Note: notice the loss of the Mirena spiral when carefully inspected hygienic pads and tampons during menstruation.If the fallout is seen, then you need to start using a condom during intercourse and seek help from a gynecologist.

Mechanical damage to the walls of the uterus - perforation

It is extremely rare to damage the uterine wall when inserting an intrauterine device, but this fact is detected immediately and immediately identified.If the perforation has not been noticed by a gynecologist, the spiral can get into other parts of the pelvis and damage the internal organs - you will need to perform a surgical intervention.

Infections

The use of intrauterine contraceptives is accompanied by some risk of infection of the pelvic organs, but the risk of their development is significantly reduced 20 days after the administration of Mirena in the uterine cavity. Infection can be triggered by pathogenic bacteria that enter the uterus cavity just during the installation of the spiral.If the infection is detected after the expiration of 20 days after the installation of the Mirena, then most likely the infection occurred during sexual intercourse with a sick partner.

The IUS is considered an effective method of preventing unwanted pregnancies.And its positive properties and minimal possibility of development of complications make this remedy even more in demand among clients of gynecological clinics.
