Uses For Skyla
Levonorgestrel-releasing intrauterine system is a device that contains the female hormone, levonorgestrel. It is placed in the uterus (womb) where it slowly releases the hormone to prevent pregnancy for up to 3 years for Skyla (TM) or up to 5 years for Mirena(R). It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.
Levonorgestrel-releasing intrauterine system is also used to treat heavy menstrual bleeding in women. It works best in women who have had at least one child.
This medicine is available only with your doctor's prescription.

Proper Use of levonorgestrel
This section provides information on the proper use of a number of products that contain levonorgestrel. It may not be specific to Skyla. Please read with care.
Your doctor will give you this medicine in a hospital or clinic. The intrauterine device (IUD) is inserted into your uterus.
This medicine comes with a patient information insert. Read and follow the instructions carefully. Ask your doctor if you have any questions.
Your doctor may want to do tests to make sure you do not have an infection before putting in an IUD. The IUD is usually inserted during your monthly period or immediately after a miscarriage or an abortion in the first trimester of your pregnancy. Putting an IUD in during a monthly period also helps to make sure that you are not pregnant. You will also need to see your doctor within 4 to 12 weeks of having your IUD placed and then once a year.
Levonorgestrel IUD has a string or "tail" which 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 string every few days during the first few months that you have your IUD. After that, check the string 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 (pointing) finger high inside your vagina. The cervix is at the top of the vagina and feels like the tip of your nose. Find the IUD string coming from your cervix. Never pull on the string. You should not be able to feel the firm plastic of the IUD itself.
- Wash your hands after you are finished checking your IUD.
You will need to have your levonorgestrel-releasing IUD replaced every 3 years for Skyla(TM), or 5 years for Mirena(R), or sooner if it comes out of your uterus.
Precautions While Using Skyla
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly and does not cause unwanted effects. These visits will usually be every 4 to 12 weeks after insertion, but some doctors require them more often.
Call your doctor right away if you think you have become pregnant while you are using this medicine. You may have a higher risk of an ectopic pregnancy if you get pregnant while your IUD is in place. An ectopic pregnancy can be a serious and life-threatening condition. It can also cause problems that may make it harder for you to become pregnant in the future.
An IUD can slip partly or all of the way out of your uterus without you knowing it. If this happens, you will have no protection against getting pregnant or you may have an increased risk for serious problems. This is more likely during the first year that you have your IUD, but can happen at any time. Regularly checking the string of your IUD can tell you if your IUD is still in place.
You may have some blood spotting and cramping during the first few weeks after the IUD has been inserted. These symptoms should go away within a few months. Rarely, the IUD may make a hole in the wall of your uterus when it is inserted. If this happens, check with your doctor right away.
An IUD increases your risk of a serious infection of the female organs called pelvic inflammatory disease (PID). PID can be serious, even life threatening. This infection could cause scarring of the female organs, which may make it hard for you to become pregnant in the future, and can increase your risk of ectopic pregnancy.
Call your doctor right away if you have flu-like symptoms, fever, chills, cramps, pain, bleeding, or fluid leaking from your vagina. These may be signs that you have an infection.
This device will not protect you from getting HIV/AIDS, herpes, or other sexually transmitted diseases. Tell your doctor if you or your partner begin to have sexual intercourse with other people, or you or your partner tests positive for a sexually transmitted disease. If this is a concern for you, talk with your doctor.
This medicine may cause changes in your blood sugar levels. Also, this medicine may cover up signs of low blood sugar, such as a rapid pulse rate. Check with your doctor if you have these problems or if you notice a change in the results of your blood or urine sugar tests.
It is important to tell your doctor that you are using this medicine before you have a medical procedure, such as magnetic resonance imaging or MRI.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
