Levonorgestrel (Into the uterus)
Prevents pregnancy and treats heavy menstrual bleeding. This is an intrauterine device (IUD), which is a reversible form of birth control. This IUD slowly releases levonorgestrel, a hormone.
Kyleena, Liletta, Mirena, SkylaThere may be other brand names for this medicine.
When This Medicine Should Not Be Used:This device is not right for everyone. Do not use it if you had an allergic reaction to levonorgestrel, silicone, polyethylene, silica, barium sulfate or iron oxide, or if you are pregnant.
How to Use This Medicine:
- A nurse or other trained health professional will give you this medicine.
- The IUD is usually inserted by your doctor during your monthly period. You will need to see your doctor 4 to 6 weeks after the IUD is placed and then once a year.
- Your IUD has a string or "tail" that is made of plastic thread. About one or two inches of this string hangs into your vagina. You cannot see this string, and it will not cause problems when you have sex. Check your IUD after each monthly period. You may not be protected against pregnancy if you cannot feel the string or if you feel plastic. Do the following to check the placement of your IUD:
- Wash your hands with soap and warm water. Dry them with a clean towel.
- Bend your knees and squat low to the ground.
- Gently put your index finger high inside your vagina. The cervix is at the top of the vagina. Find the IUD string coming from your cervix. Never pull on the string. You should not be able to feel the plastic of the IUD itself. Wash your hands after you are done checking your IUD string.
- Your doctor will need to remove your IUD after 3 years for Skyla®, after 5 years for Kyleena, or after 6 years for Liletta® or Mirena®. You will also need to have it replaced if it comes out of your uterus. If you are using Mirena® or Liletta® and want to stop, your doctor can remove it at any time. However, you may become pregnant as soon as Kyleena, Liletta®, Mirena®, or Skyla® is removed or if you have intercourse the week before Liletta® is removed. Use another form of birth control or have a new IUD inserted to keep from getting pregnant.
Drugs and Foods to Avoid:
Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.
- Some medicines can affect how this device works. Tell your doctor if you are using a blood thinner (including warfarin).
Warnings While Using This Medicine:
- Tell your doctor if you are breastfeeding, or if you had a baby, miscarriage, or abortion in the past 3 months. Tell your doctor if you have liver disease (including tumor or cancer), heart disease, breast cancer, heart or blood circulation problems, migraine, high blood pressure, or a history of heart valve problems, blood clotting problems, stroke, or heart attack. Tell your doctor if you have problems with your immune system or have had surgery on your female organs (especially fallopian tubes).
- Tell your doctor if you have had any problems, infections, or other conditions that affected your reproductive system. There are many problems that could make an IUD a bad choice for you, including if you have fibroids, unexplained bleeding, a uterus that has an unusual shape, a recent infection, a history of pelvic inflammatory disease, an abnormal Pap test, ectopic pregnancy, cancer or suspected cancer, or an existing IUD.
- There is a small chance that you could get pregnant when using an IUD, just as there is with any birth control. If you get pregnant, your doctor may remove your IUD to lower the risk of miscarriage or other problems.
- This medicine may cause the following problems:
- Increased risk of ectopic pregnancy (pregnancy outside the uterus)
- Increased risk of serious infections, including sepsis
- Increased risk of pelvic inflammatory disease (PID) or endometritis
- Perforation (hole in the wall of your uterus), which can damage other organs
- Increased risk for ovarian cysts
- Increased risk of cancer of the breast, uterus, or cervix
- Increased risk of high blood pressure, stroke, heart attack, or clotting problems
- Jaundice (yellow skin or eyes)
- You might have some spotting and cramping during the first weeks after the IUD has been inserted. These symptoms should decrease or go away within a few weeks up to 6 months.
- You could have less bleeding or even stop having periods by the end of the first year. Call your doctor if you have a change from your regular bleeding pattern after you have had your IUD for awhile, including more bleeding or if you miss a period (and you were having periods even with your IUD).
- An IUD can slip partly or all the way out of your uterus. If this happens, use condoms or another form of birth control, and call your doctor right away.
- This IUD will not protect you from HIV/AIDS or other sexually transmitted diseases.
- If you have the Skyla® or Kyleena, tell your doctor before you have an MRI test.
- Your doctor will check your progress and the effects of this medicine at regular visits. Keep all appointments.
