What is Norplant System (levonorgestrel intrauterine system)?
Levonorgestrel is a female hormone that can cause changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus. Levonorgestrel intrauterine system is a plastic device that contains this hormone. This device is placed in the uterus where it slowly releases the hormone to prevent pregnancy for 3 to 5 years.
Mirena is meant for use in a woman who has had at least one child. Skyla or Liletta can be used whether you have children or not. Mirena is also used in women who have heavy menstrual bleeding and choose to use an intrauterine form of birth control.
Levonorgestrel is a progestin hormone and does not contain estrogen. The intrauterine device release levonorgestrel in the uterus, but only small amounts of the hormone reach the bloodstream. 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 should I discuss with my healthcare provider before taking Norplant System (levonorgestrel intrauterine system)?
An intrauterine device 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 and about ways to help prevent a pelvic infection.

abnormal vaginal bleeding that has not been checked by a doctor;
an untreated or uncontrolled pelvic infection (vaginal, cervical uterine, or bladder);
endometriosis or a serious pelvic infection following a pregnancy or abortion within the past 3 months;
a history of pelvic inflammatory disease (PID), unless you have had a normal pregnancy after the infection was treated and cleared;
uterine fibroid tumors or other conditions that affect the shape of the uterus;
past or present breast cancer, known or suspected cervical or uterine cancer;
liver disease or liver tumor (benign or malignant);
a recent abnormal Pap smear that has not yet been diagnosed or treated;
a disease or condition that weakens your immune system, such as AIDS, leukemia, or IV drug abuse; or

high blood pressure, heart disease or a heart valve disorder;
history of heart attack or stroke;
a bleeding or blood-clotting disorder;
a vaginal infection, pelvic infection, or sexually transmitted disease; or
Do not use levonorgestrel intrauterine system during pregnancy. This device 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 choose to continue a pregnancy that occurs while using a levonorgestrel intrauterine system, watch for signs of infection such as fever, chills, flu symptoms, cramps, vaginal bleeding or discharge.
If you have recently had a baby and are breast-feeding, wait until your baby is at least 6 weeks old before you start using the intrauterine system.
How is levonorgestrel intrauterine system used?
Levonorgestrel intrauterine system is a T-shaped plastic device that 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 intrauterine device. 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 recommended by your doctor.
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 device has slipped lower in your uterus or out of your uterus. A sudden increase in menstrual flow may be a sign that the device has slipped out of place.
If you think the device is not properly in place, use a non-hormone method of birth control (condom, or diaphragm with spermicide) to prevent pregnancy until your doctor is able to replace the levonorgestrel device.
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.
If you need to have an MRI (magnetic resonance imaging), tell your caregivers ahead of time that you have an intrauterine device in place.
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. Call your doctor if you miss a period or think you might be pregnant.
Your device may be removed at any time you decide to stop using birth control. The Mirena intrauterine system must be removed at the end of the 5-year wearing time. The Skyla or Liletta device 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 intrauterine device. Do not attempt to remove the device yourself.
Following removal of the levonorgestrel intrauterine device, you may become pregnant right away.
What happens if I miss a dose?
Since the intrauterine device 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 Norplant System (levonorgestrel intrauterine system)?
Avoid having more than one sexual partner. The intrauterine device 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. Contact your doctor if your sexual partner develops HIV or a sexually transmitted disease, or if you have any change in sexual relationships.

Your doctor may need to surgically remove the device.

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;

headache, depression, mood changes;
back pain, breast tenderness or pain;
