Progesterone Intrauterine Device (IUD)
In the U.S.-
A progesterone intrauterine device (proe-JES-ter-one IN-tra-YOU-ta-rin de-VICE) (also called an IUD) is inserted by a health care professional into a woman's uterus as a contraceptive (birth control method).
The progesterone IUD works by causing changes in the uterus that help to prevent pregnancy. The fertilization of the woman's egg with her partner's sperm is less likely with an IUD in place, but it can occur. Even so, the IUD makes it harder for the fertilized egg to become attached to the uterus walls, making it hard to become pregnant. The hormone, progesterone, released from the IUD is believed to improve the effects of the device. After the IUD is removed, most women trying to become pregnant can become pregnant.
Studies have shown that pregnancy can occur in up to 2 of each 100 women using a progesterone IUD during the first year of use . Other birth control methods such as not having intercourse, taking birth control pills (the Pill), or having surgery to become sterile are as effective or more effective. Methods that do not work as well include using condoms, diaphragms, vaginal sponges, or spermicides. Discuss with your health care professional what your options are for birth control and the risks and benefits of each method.
IUDs do not protect a woman from sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) . The use of latex (rubber) condoms or abstinence (not having intercourse) is recommended for protection from these diseases.
Your lifestyle will determine how safe and reliable the progesterone IUD will be for you . Problems that may occur with use of an IUD are far less likely to occur in women who have a long-term relationship with one sexual partner. Also, it is important that your sexual partner not have any other sexual partners. If you or your partner has more than one sexual partner it increases your chance of getting an infection in the vagina. If an infection is present in the vagina or uterus when the IUD is in the uterus it may make an infection more serious. If your lifestyle changes while you are using an IUD or you get or are exposed to a sexually transmitted disease, call your health care professional .
Progesterone IUDs are available only from your doctor or other authorized health care professional in the following form:
Before Using This Medicine
In deciding whether to use a progesterone IUD as a method of birth control, you need to consider the risks of using it as well as the good it can do. This is a decision you, your sexual partner, and your health care professional will make. For progesterone IUDs, the following should be considered:
Pregnancy- IUD use is not recommended during pregnancy or if you plan to become pregnant in the near future. It is also not recommended in women who have had a pregnancy develop outside of the uterus (ectopic pregnancy).
There is a rare chance that a woman can become pregnant with the IUD in the uterus. If this happens, it is recommended that the IUD be removed or that the pregnancy be ended within the first 3 months. If the pregnancy continues, removing the IUD decreases the chance of a problem developing. However, whether the IUD is removed or not, some problems can occur. Some of these problems include miscarriage, premature labor and delivery, infection, and, very rarely, death of the mother.
Your health care professional will help you decide on the proper time to begin using an IUD after delivering a baby. Sometimes problems can occur if you start using the IUD too soon after delivery. These problems include having the IUD move out of place or having it press into the walls of the uterus or the cervix (opening to the uterus). These problems may harm the cervix or uterus, causing pain or unusual uterine bleeding. Call your health care professional immediately if you have any problems.
Breast-feeding- The progesterone IUD has not been shown to cause problems in nursing babies and its use is recommended for those women needing contraception while breast-feeding.Teenagers- Sexually active teenagers are strongly encouraged to use a contraceptive method that protects them against sexually transmitted diseases (STDs).
Teenagers who have not had children usually have more side effects than teenagers or adults who have had children. In teenagers who have not had children, the IUD may move out of place. This may harm the uterus or cervix. Abdominal pain and increased menstrual bleeding also are more common in teenagers than in women who are older and have had children.
Other medical problems- The presence of other medical problems may affect the use of progesterone IUDs. Make sure you tell your health care professional if you have any other medical problems, especially:
Proper Use of This Medicine
IUDs come with patient information. You must understand this information . You should keep a copy for reference. Be sure you understand possible problems with the progesterone IUD, especially side effects, risks, and warning signs of trouble .
Spermicides such as contraceptive foams or creams are not needed to prevent pregnancy with a properly placed progesterone IUD.
It is important that you check for the IUD threads every month (if not more often) especially after each menstrual period . Feeling the IUD threads near the cervix lets you know that the progesterone IUD is still in place.
To check for the IUD threads :
Follow your health care professional's orders to schedule the proper time to remove and replace your progesterone IUD, usually at 12 months . You and your health care professional may choose to replace it sooner or begin a new method of birth control.
Precautions While Using This Medicine
It is very important to keep all medical appointments with your health care professional during the first year of IUD use . This will allow the health care professional to make sure that the device is still in place and working properly.
Check with your medical doctor if you plan to have surgery of the uterus or fallopian tubes . Your doctor may remove your IUD before the surgery or help you choose another type of treatment.
Tell your doctor immediately if you think that the IUD has moved out of place. Do not try to put the IUD back into place inside the uterus. Do not try to remove the IUD .
Although IUDs are very reliable, there is a rare chance that the IUD may fail to protect some people from becoming pregnant. Very rarely a pregnancy can occur outside of the uterus; this is called an ectopic pregnancy. It can be hard to tell if an ectopic pregnancy has occurred. Unlike a normal pregnancy in the uterus, which stops the menstrual period, some people can still have a menstrual period with an ectopic pregnancy. These women may not think they are pregnant.
Notify your doctor immediately if you feel many of the following changes that can occur with a pregnancy : Enlarged or tender breasts, lack of or unusual menstrual period, lower abdominal pain or cramping (possibly severe), sore abdomen, unusual tiredness or weakness, unusual uterine bleeding (in some cases, very heavy).
If you think you are pregnant or if you miss a period while you are using the IUD, tell your health care professional . Until your doctor is able to see you, use another birth control method, such as condoms, to prevent pregnancy just in case you are not pregnant.
Also, notify your doctor and use another birth control method, such as condoms , if:
You can use other products in the vagina, such as tampons or condoms, while you are using a progesterone IUD.
After you stop using this device, you may become pregnant. The contraceptive effect of a progesterone IUD is usually reversible. If you stop using an IUD and still do not want to become pregnant, you should begin using another contraceptive method immediately to prevent pregnancy.
