Levonorgestrel
Kyleena is an intrauterine therapeutic system in the shape of the letter "T", also known as a hormonal intrauterine device. It prevents pregnancy for up to five years - it is a contraceptive. The Kyleena system contains a hormone called levonorgestrel.

Removal threads
The doctor will place the Kyleena system in the uterus. After its insertion, a small amount of hormone is continuously released.
Kyleena prevents sperm from coming into contact with the egg, and thus prevents pregnancy.
This works as follows:

The doctor must be sure that this contraceptive is suitable for the woman. Therefore, they will first ask a few questions about her health. Only then will it be possible to obtain a prescription.
As a contraceptive, Kyleena prevents pregnancy. However, no contraceptive prevents all pregnancies. Each year, about 2-3 out of 1000 women using the Kyleena system become pregnant.
This system does not protect against HIV or other sexually transmitted diseases.
This system is not an emergency contraceptive, such as the "morning after" pill. Women who have had unprotected sex shortly before its insertion may become pregnant.
Kyleena should not be used if any of the above situations apply to the woman - in case of doubt, consult a doctor.
If any of these situations apply to the woman (or if the woman is unsure), she should discuss this with her doctor before inserting Kyleena.
If any of the above symptoms occur, the woman should immediately consult her doctor.
The woman should also discuss Kyleena with her doctor if:
The doctor will decide whether continued use of Kyleena is still safe for the woman.
Signs that Kyleena may not be in the correct position include:
These symptoms may indicate that Kyleena has been expelled - see section 4, subsection "Expulsion of Kyleena". Or it may indicate that perforation has occurred - see section 4, subsection "Perforation".
If the woman experiences any of the signs that Kyleena is not in the correct position, she should immediately consult her doctor. The woman should not have sexual intercourse unless a condom or diaphragm is used until the doctor checks that the system is still in the correct position.
The woman's partner may feel the Kyleena threads during intercourse. This does not mean that Kyleena is not in the correct position. However, if the partner feels uncomfortable feeling the threads, there are ways the doctor can help.
During menstruation, it is recommended to use sanitary pads. If tampons or menstrual cups are used, they should be changed carefully. Otherwise, the woman may accidentally pull on the Kyleena threads. If the woman thinks that the system has been displaced (see the list of possible signs above), she should not have sexual intercourse until she visits her doctor, unless a condom or diaphragm is used.
Some women using hormonal contraceptives, including Kyleena, experience depression or low mood. More information can be found in section 4, subsection "Mental health problems".
Girls who have not yet started menstruating should not use Kyleena.
The woman should tell her doctor about all medicines she is currently taking or has recently taken, as well as any medicines she plans to take.
Kyleena should not be inserted during pregnancy.
Stop of menstrual bleeding during use of Kyleena
In some women, menstrual bleeding may not occur during use of Kyleena. If menstrual bleeding has already stopped, it is likely due to Kyleena. More information on this can be found in section 4, subsection "Irregular or rare menstrual bleeding".
Has menstrual bleeding not occurred for 6 weeks? In this case, a pregnancy test can be done.
If the test shows that the woman is not pregnant, there is no need to repeat it.
In case of symptoms of pregnancy
In case of symptoms of pregnancy, such as missed menstrual bleeding, nausea, and tender breasts, the woman should:
In case of pregnancy
If the woman becomes pregnant while using Kyleena, she should immediately contact her doctor. The doctor will decide whether to remove Kyleena.
Removal of Kyleena is associated with a risk of miscarriage. However, leaving the inserted Kyleena system in place during pregnancy may increase the risk of:
The woman should discuss with her doctor the benefits and risks of continuing the pregnancy with the Kyleena system in place. The doctor will closely monitor the woman. The woman should immediately contact her doctor if she experiences:
Kyleena contains a hormone called levonorgestrel. The woman should ask her doctor about the potential effect of the hormone on the developing fetus. Very few reports have been made of the effect of levonorgestrel on the genital organs of female fetuses in the womb.
Ectopic pregnancy
The risk of becoming pregnant while using Kyleena is very low. If the woman does become pregnant while using Kyleena, there is a higher risk that the fertilized egg (embryo) will not implant in the uterus, but in the fallopian tube or abdominal cavity (ectopic pregnancy). This type of pregnancy is a serious condition that requires immediate medical attention. After an ectopic pregnancy, it may be more difficult to become pregnant again. See section 4, subsection "Ectopic pregnancy".
Breastfeeding
Kyleena can be used during breastfeeding. A small amount of hormone passes into breast milk. However, Kyleena does not affect the quality or quantity of breast milk or the growth and development of the breastfed infant.
Fertility
If the woman wants to become pregnant, she should contact her doctor to have Kyleena removed.
Kyleena does not affect fertility after its removal.
Kyleena has no known effect on the ability to drive or use machines.
Kyleena is not an emergency contraceptive, such as the "morning after" pill.
Kyleena can be inserted immediately after a miscarriage, if the pregnancy lasted less than 3 months and there are no genital tract infections, and it will work immediately.
The system can be replaced with a new one at any time during the menstrual cycle, and it will work immediately.
Sometimes, before inserting Kyleena, the doctor may perform certain examinations, such as:
Insertion of Kyleena
First, the doctor will examine the size of the uterus and its position in the abdominal cavity (pelvic examination).
The doctor will insert a device (speculum) into the vagina and clean the cervix with an antiseptic solution. Sometimes, the doctor may use local anesthesia on the cervix. Then, the doctor will insert Kyleena into the uterus through a thin, flexible, plastic tube (applicator).
Sometimes, the insertion of Kyleena may cause discomfort. Some women may feel dizzy or faint. There may also be pain or slight bleeding from the vagina. This is not unusual.
After the insertion is complete, the doctor will give the woman a patient reminder card. This card can be used to record the dates of subsequent Kyleena checks. The woman should bring this card to every visit.
Follow-up after insertion
Kyleena should be checked by a doctor 4-6 weeks after its insertion.
The doctor will decide how often subsequent check-ups should be. Kyleena should be checked at least once a year during a visit. The woman should bring the patient reminder card to every visit.
How to check yourself that Kyleena is in the correct position
This can be checked by gently inserting a finger into the vagina. The threads should be felt at the end of the vagina, near the cervix. The cervix is the entrance to the uterus. Note: Do not pull on the threads, as this can cause the Kyleena system to be accidentally removed.
If the threads are not felt, the doctor must check that Kyleena is still in the correct position. The woman should not have sexual intercourse unless a condom or diaphragm is used until she visits her doctor.
If the woman or her partner can feel the lower plastic end of the Kyleena frame- Kyleena is not in the correct position. The woman should immediately contact her doctor. The woman should not have sexual intercourse until she visits her doctor, unless a condom or diaphragm is used.
Kyleena works for up to 5 years. It should be removed after 5 years, but it can also be removed at any time before 5 years. The doctor will remove the system. After its removal, the woman can become pregnant.
Removal of Kyleena may be uncomfortable. Some women may feel dizzy or faint during or immediately after removal. There may also be slight pain or bleeding from the vagina. This is not unusual.
Continuing contraception after removal
If the woman does not want to become pregnant after Kyleena is removed, she should know that:
Like all medicines, Kyleena can cause side effects, although not everybody gets them.
There are certain severe side effects, which means that if they occur, the woman should immediately contact her doctor:
If the woman thinks that any of the above points apply to her, she should immediately contact her doctor.
The following are other side effects that may occur. The most common side effects are at the top of the list, and the rarest are at the bottom.
Very common side effects:occur in more than 1 in 10 people
Common side effects:occur in less than 1 in 10 people
Uncommon side effects:occur in less than 1 in 100 people
Symptoms of an ectopic pregnancy include:
The woman should immediately contact her doctor if she experiences any of these symptoms.
The risk of becoming pregnant while using Kyleena is very low. If the woman does become pregnant while using Kyleena, there is a higher risk that the fertilized egg (embryo) will not implant in the uterus, but in the fallopian tube or abdominal cavity (ectopic pregnancy). This type of pregnancy is a serious condition that requires immediate medical attention. About 2 out of 1000 women using Kyleena for a year will have an ectopic pregnancy. This type of pregnancy can require surgery.
Some women are more likely to have an ectopic pregnancy. These include women:
It is likely that menstrual bleeding will change due to the use of Kyleena. For example:
Sometimes, these changes occur only in the first few months after insertion. For example:
Gradually, the woman may experience less intense menstrual bleeding, and menstrual bleeding may become shorter. Eventually, some women may stop menstruating altogether.
No menstrual bleeding? This is usually normal. In most cases, it does not mean that the woman is pregnant or going through menopause. The reason is that normally, the uterine lining thickens every month to prepare for pregnancy, and then becomes thinner again due to menstruation. Kyleena reduces the thickening of the uterine lining. This can cause menstrual bleeding to stop.
Hormone levels usually remain normal.
After removal of Kyleena, normal menstrual bleeding usually returns. If it does not, the woman should contact her doctor.
Kyleena does not contain bacteria, viruses, or fungi (it is sterile). This also applies to the applicator. However, a pelvic infection can still occur during the insertion of Kyleena or within the first 3 weeks after its insertion. For example, in the uterine lining, fallopian tubes, or ovaries. This can affect less than 1 in 10 women.
The following may occur:
The risk of pelvic infection is higher if:
In case of a pelvic infection, it is essential to immediately contact a doctor. A pelvic infection can cause:
Kyleena must be removed if a pelvic infection:
Kyleena may be expelled or fall out. This is caused by uterine contractions during menstruation. This can occur in less than 1 in 10 women, especially if:
If Kyleena is not in the correct position, it may not work properly. The risk of becoming pregnant is higher in this case. If it is expelled, it will no longer prevent pregnancy.
If Kyleena is not in the correct position or has been expelled, the woman may experience pain or bleeding from the vagina that is different from normal. It is also possible that Kyleena has been expelled without the woman noticing.
Kyleena usually reduces the amount of blood lost during menstruation.
The longer the woman uses it, the less blood she loses during menstruation. This means that if the woman suddenly starts to lose more blood during menstruation again, Kyleena may have been expelled.
In section 3, "How to check yourself that Kyleena is in the correct position", you can find information on how to check if it is in the correct position and what to do if you suspect that it is no longer in the correct position.
It may happen that Kyleena is pushed into the uterine wall or through the uterine wall. This is called perforation. Perforation usually occurs during the insertion of Kyleena.
Perforation does not always cause pain, so it may only be noticed later. If Kyleena is no longer in the correct position due to perforation, it will not prevent pregnancy. The doctor must then remove it as soon as possible. Sometimes, surgery is necessary.
Perforation occurs in less than 1 in 1000 women. The risk of perforation is higher (in less than 1 in 100 women) if:
Perforation may have occurred if:
If the woman thinks that perforation may have occurred, she should immediately contact her doctor.
The woman should tell her doctor about Kyleena, especially if it is not the same doctor who inserted the system.
Sometimes, during the use of Kyleena, a small, fluid-filled sac (cyst) forms on the ovary.
Symptoms of an ovarian cyst may include:
The ovarian cyst usually resolves on its own. However, it may require medical attention. In rare cases, surgery may be necessary. If the woman thinks that she may have an ovarian cyst, she should contact her doctor.
Some women using hormonal contraceptives, including Kyleena, experience depression or low mood.
Depression can be severe and sometimes lead to suicidal thoughts. If there are changes in mood and symptoms of depression, the woman should contact her doctor as soon as possible. Depression and low mood can occur in less than 1 in 100 women using Kyleena.
If side effects occur, including any side effects not listed in this leaflet, the woman should consult her doctor or nurse. Side effects can be reported directly to the Department of Drug Safety, Office for Registration of Medicinal Products, Medical Devices, and Biocidal Products, Al.
