What is levonorgestrel intrauterine system?
Levonorgestrel is a female hormone that can cause changes in your cervix and uterus. Levonorgestrel intrauterine system is a T-shaped plastic intrauterine device (IUD) that is placed in the uterus where it slowly releases the hormone.
Levonorgestrel intrauterine system used to prevent pregnancy for 3 to 6 years. You may use this IUD whether you have children or not. Mirena is also used to treat heavy menstrual bleeding in women who choose to use an intrauterine form of birth control.
Levonorgestrel is a progestin and does not contain estrogen. Levonorgestrel intrauterine system should not be used as emergency birth control.
Levonorgestrel intrauterine system may also be used for purposes not listed in this medication guide.
What are the possible side effects of levonorgestrel intrauterine system?
Get emergency medical help if you have severe pain in your lower stomach or side. This could be a sign of a tubal pregnancy (a pregnancy that implants in the fallopian tube instead of the uterus). A tubal pregnancy is a medical emergency.
The levonorgestrel IUD may become embedded into the wall of the uterus, or may perforate (form a hole) in the uterus. If this occurs, the device may no longer prevent pregnancy, or it may move outside the uterus and cause scarring, infection, or damage to other organs. Your doctor may need to surgically remove the device.
Call your doctor at once if you have:
- severe cramps or pelvic pain, pain during sexual intercourse;
- extreme dizziness or light-headed feeling;
- severe migraine headache;
- heavy or ongoing vaginal bleeding, vaginal sores, vaginal discharge that is watery, foul-smelling discharge, or otherwise unusual;
- pale skin, weakness, easy bruising or bleeding, fever, chills, or other signs of infection;
- jaundice (yellowing of the skin or eyes); or
- sudden numbness or weakness (especially on one side of the body), confusion, problems with vision, sensitivity to light.
Common side effects may include:
- pelvic pain, vaginal itching or infection, missed or irregular menstrual periods, changes in bleeding patterns or flow (especially during the first 3 to 6 months);
- temporary pain, bleeding, or dizziness during insertion of the IUD;
- ovarian cysts (pelvic pain that disappears within 3 months);
- stomach pain, nausea, vomiting, bloating;
- headache, migraine, depression, mood changes;
- back pain, breast tenderness or pain;
- weight gain, acne, changes in hair growth, loss of interest in sex; or
- puffiness in your face, hands, ankles, or feet.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the most important information I should know about levonorgestrel intrauterine system?
You should not use this device if you have abnormal vaginal bleeding, a pelvic infection, certain other problems with your uterus or cervix, or if you have breast or uterine cancer, liver disease or liver tumor, or a weak immune system.
Do not use during pregnancy. Call your doctor if you think you might be pregnant.
What should I discuss with my healthcare provider before using levonorgestrel intrauterine system?
An IUD can increase your risk of developing a serious pelvic infection, which may threaten your life or your future ability to have children. Ask your doctor about your personal risk.
Do not use during pregnancy. This IUD can cause severe infection, miscarriage, premature birth, or death of the mother if left in place during pregnancy. Tell your doctor right away if you become pregnant. If you continue a pregnancy that occurs while using this IUD, watch for signs such as fever, chills, cramps, vaginal bleeding or discharge.
You should not use this device if you are allergic to levonorgestrel, silicone, silica, silver, barium, iron oxide, or polyethylene, or if you have:
- abnormal vaginal bleeding that has not been checked by a doctor;
- an untreated or uncontrolled pelvic infection (vaginal, cervical, uterine);
- endometriosis or a serious pelvic infection following a pregnancy or abortion in the past 3 months;
- pelvic inflammatory disease (PID), unless you had a normal pregnancy after the infection was treated and cleared;
- uterine fibroid tumors or conditions that affect the shape of the uterus;
- past or present cancer of the breast, cervix, or uterus;
- liver disease or liver tumor (benign or malignant);
- a condition that weakens your immune system, such as AIDS, leukemia, or IV drug abuse; or
- if you have another intrauterine device (IUD) in place.
Tell your doctor if you have ever had:
- high blood pressure, heart problems, a heart valve disorder, a heart attack or stroke;
- bleeding problems;
- migraine headaches; or
- a vaginal infection, pelvic infection, or sexually transmitted disease.
You should not use this IUD if you are breastfeeding a baby younger than 6 weeks old. This IUD may be more likely to form a hole or get embedded in the wall of your uterus if you have the device inserted while you are breastfeeding.
How is levonorgestrel intrauterine system used?
The levonorgestrel IUD is inserted through the vagina and placed into the uterus by a doctor. The device is usually inserted within 7 days after the start of a menstrual period.
You may feel pain or dizziness during insertion of the IUD. You may also have minor vaginal bleeding. Tell your doctor if you still have these symptoms longer than 30 minutes.
The levonorgestrel device should not interfere with sexual intercourse, wearing tampons, or using other vaginal medications.
Your doctor will need to see you within a few weeks after insertion of the device to make sure it is still in place correctly. You will also need regular annual pelvic exams and Pap smears.
You may have irregular periods during the first 3 to 6 months of use. Your flow may be lighter or heavier, and you may eventually stop having periods after several months. Tell your doctor if you do not have a period for 6 weeks or if you think you might be pregnant.
The IUD may come out by itself. After each menstrual period, make sure you can still feel the removal strings. Wash your hands with soap and water, and insert your clean fingers into the vagina. You should be able to feel the strings at the opening of your cervix.
Call your doctor at once if you cannot feel the strings, or if you think the IUD has slipped lower or has come out of your uterus, especially if you also have pain or bleeding. Use a non-hormone method of birth control (condom, diaphragm, cervical cap, or contraceptive sponge) to prevent pregnancy until your doctor is able to replace the IUD.
Your device may be removed at any time you decide to stop using birth control. The Mirena IUD must be removed at the end of the 6-year wearing time. Kyleena must be removed after 5 years, and Skyla or Liletta must be removed after 3 years. Your doctor can insert a new device at that time if you wish to continue using this form of birth control. Only your doctor should remove the IUD. Do not attempt to remove the device yourself.
If you wish to continue preventing pregnancy, you may need to start using another birth control method a week before your levonorgestrel intrauterine system is removed.
What happens if I miss a dose?
Since the IUD continuously releases a low dose of levonorgestrel, missing a dose does not occur when using this form of levonorgestrel.
What happens if I overdose?
An overdose of levonorgestrel released from the intrauterine system is very unlikely to occur.
What should I avoid while using levonorgestrel intrauterine system?
Avoid having more than one sex partner. The IUD can increase your risk of developing a serious pelvic infection, which is often caused by sexually transmitted disease. Levonorgestrel intrauterine system will not protect you from sexually transmitted diseases, including HIV and AIDS. Using a condom is the only way to help protect yourself from these diseases.
Call your doctor if your sex partner develops HIV or a sexually transmitted disease, or if you have any change in sexual relationships.
What other drugs will affect levonorgestrel intrauterine system?
Some drugs can affect your blood levels of levonorgestrel, which could make this form of birth control less effective. Tell your doctor about all your other medicines, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
Where can I get more information?
Your doctor or pharmacist can provide more information about the levonorgestrel intrauterine system.
