IUD with Hormone--Mirena
The Abortion Clinic Directory

What is Mirena?
Mirenaô (levonorgestrel-releasing intrauterine system) is a unique form of long-acting birth control that is inserted into the uterus by your doctor or practitioner and lasts up to five years.
∑ Small, T-shaped frame is made of soft, flexible plastic about the size of a quarter
∑ Placed in your uterus by your healthcare provider during a routine office visit
∑ Continuously releases a very small amount of levonorgestrel (a hormone commonly found in some birth control pills)
∑ Prevents pregnancy for up to 5 years or until removed

Who can use Mirena?
Mirena is most appropriate for women who:
∑ Have had at least 1 child
∑ Are looking for an effective, reversible form of birth control that's easy to use
∑ Are in a monogamous relationship

How does Mirena work?
There is no single explanation of how Mirena works.

Mirena may:
∑ Block sperm from reaching or fertilizing your egg
∑ Make the lining of your uterus thin
∑ Stop the release of your egg from your ovary, but this is not the way it works in most cases. We do not know which of these actions is most important for preventing pregnancy and most likely all of them work together.

Is Mirena safe and effective?
Over the past 14 years, Mirena has been used successfully by more than 7 million women worldwide. It is 99.9% effective and has been approved by the FDA for use in the US since 2001. By 1 year of use, there is a 90% reduction in menstrual bleeding and about 20% of users have no bleeding or spotting at all.

How is Mirena inserted?
Mirena is placed in your uterus by your healthcare provider during a routine office visit. Your healthcare provider will:
∑ Clean your vagina and cervix with an antiseptic solution
∑ Insert a thin tube of flexible plastic containing Mirena into your vagina and then into your uterus
∑ Check to make sure Mirena is positioned correctly
∑ Withdraw the plastic tube, leaving Mirena in your uterus
∑ Trim the removal strings to the proper length
The procedure for placing Mirena in your uterus takes only a few minutes.
Most women experience some discomfort while Mirena is being placed in your uterus. Uterine cramps, which feel like menstrual cramps, and dizziness may also occur, but typically disappear within a day or two.

How will Mirena affect my period?
At first, you may experience spotting (a small amount of blood loss) or light bleeding requiring sanitary protection in addition to your monthly period.
∑ This usually occurs during the first 3 to 6 months after Mirena is placed
∑ During this time, your period may become irregular
∑ A few women may have heavy or prolonged bleeding during this time
After this brief adjustment period, your number of bleeding days is likely to decrease, and your periods may even stop altogether. By 1 year of use, there is a 90% reduction in menstrual bleeding and about 20% of users have no bleeding or spotting at all.

Is it abnormal not to have periods?
Not having your period while you are using Mirena is not abnormal or harmful. Mirena may cause your periods to stop because:
∑ The levonorgestrel in Mirena reduces the monthly thickening of the lining of your uterus
∑ Less thickening means less menstrual flow
∑ Eventually, your menstrual flow may stop completely
∑ Once Mirena is removed, your menstrual cycle will return to the way it was before you used Mirena
During the first 6 weeks of use, you should contact your healthcare provider to rule out pregnancy if you do not get your period or if you have other symptoms of pregnancy.

How will my healthcare provider know whether Mirena is right for me?
Choosing the best birth control method is a personal decision that should be made by a woman in partnership with her healthcare provider. To help you make the right choice about Mirena, your healthcare provider will need to know whether you:
∑ Are in a stable relationship in which both you and your partner are not having sex with other people
∑ Have ever had a pelvic infection (referred to as pelvic inflammatory disease or PID)
∑ Recently had a baby or are breast feeding
∑ Are diabetic
∑ Were born with heart disease or have heart valve problems
∑ Have problems with blood clotting or take medicine to reduce blood clotting

Advantages of Mirena
∑ Highly effective, 99.9%
∑ Lasts for five years
∑ Menstrual flow may lighten or disappear
∑ May help prevent ovarian and endometrial cancer
∑ Less expensive than most methods because it lasts 5 years.

Disadvantages of Mirena
∑ Can be expensive at time of insertion without insurance coverage
∑ May cause irregular bleeding or loss of periods, which some women donít like
∑ May cause cramping, usually in the first 6 months
∑ Must be inserted by a health care provider.
∑ No protection against STDís

How can I get Mirena?
