Mirena is a small t-shaped device that is placed in your uterus by a healthcare professional

You may experience pain, bleeding or dizziness during and after placement. If your symptoms do not pass within 30 minutes after placement, Mirena may not have been placed correctly. Your healthcare provider will examine you to see if Mirena needs to be removed or replaced.

How small is Mirena?

Mirena is about the size of a sugar packet

Some serious risk considerations about Mirena

Although pregnancy while using Mirena is uncommon (less than 1 in 100), it can be serious. Call your healthcare professional right away if you think you are pregnant. If you get pregnant while using Mirena, you may have an ectopic pregnancy. This means that the pregnancy is not in the uterus. Unusual vaginal bleeding or abdominal pain, especially with missed periods, may be a sign of ectopic pregnancy. Ectopic pregnancy is a medical emergency that often requires surgery. Ectopic pregnancy can cause internal bleeding, infertility, and even death. There are also risks if you get pregnant while using Mirena and the pregnancy is in the uterus. Severe infection, miscarriage, premature delivery, and even death can occur with pregnancies that continue with an intrauterine device (IUD). Because of this, your healthcare professional may try to remove Mirena, even though removing it may cause a miscarriage. If Mirena cannot be removed, talk with your healthcare professional about the benefits and risks of continuing the pregnancy. If you continue your pregnancy, see your healthcare professional regularly. Call your healthcare professional right away if you get flu-like symptoms, fever, chills, cramping, pain, bleeding, vaginal discharge, or fluid leaking from your vagina. These may be signs of infection. It is not known if Mirena can cause long-term effects on the fetus if it stays in place during a pregnancy.

2,191 daily pills over 6 years versus 1 Mirena® IUD

Mirena is a pill-free birth control option

In a study of over 4,500 women around the world, including 500 women in the United States aged 21–29 years who take a daily birth control pill, 82% of US women reported* forgetting to take it at least once in the past 12 months.† 

 

Mirena lasts up to 6 years for pregnancy prevention, and eliminates the responsibility of taking a daily pill—that’s 2,191 daily pills over 6 years vs 1 Mirena IUD. Monthly pharmacy trips for birth control refills are a thing of the past! But you will need to do a thread check 1 time a month to make sure Mirena is still in place. Your healthcare professional can teach you how.

 

Within 4 to 6 weeks of placement, you should return for a follow-up visit. If you don't feel the threads or feel more than just the threads, call your healthcare professional. Mirena may not be in the right position and may not prevent pregnancy. Use non-hormonal back-up birth control (such as condoms and spermicide) until your healthcare professional can check that Mirena is still in the right place.

*When asked, "In the past 12 months, have you ever forgotten to take your pill?"

Based on a study conducted by Opinion Health on behalf of Bayer Pharmaceuticals Division, conducted in June/July 2016.

INDICATION FOR MIRENA

Mirena® (levonorgestrel-releasing intrauterine system) is a hormone-releasing IUD that prevents pregnancy for up to 6 years. Mirena also treats heavy periods for up to 5 years in women who choose intrauterine contraception.

 

IMPORTANT SAFETY INFORMATION

  • If you have an untreated genital infection, get infections easily, or have certain cancers, don't use Mirena. Less than 1% of users get a serious pelvic infection called pelvic inflammatory disease (PID).
  • If you have persistent pelvic or stomach pain, excessive bleeding after placement, or if Mirena comes out, tell your healthcare professional (HCP). If Mirena comes out, use back-up birth control. Mirena may go into or through the wall of the uterus and cause other problems.
  • Pregnancy while using Mirena is uncommon but can be life threatening and may result in loss of pregnancy or fertility.

  • Ovarian cysts may occur but usually disappear.
  • Bleeding and spotting may increase in the first 3 to 6 months and remain irregular. Periods over time usually become shorter, lighter, or may stop.

 

Mirena does not protect against HIV or STDs.

 

Only you and your HCP can decide if Mirena is right for you. Mirena is available by prescription only.
