Some serious risk considerations about Kyleena

Although pregnancy while using Kyleena is uncommon (less than 1 in 100), it can be serious. Call your healthcare professional right away if you think you may be pregnant. If possible, also do a urine pregnancy test. If you get pregnant while using Kyleena, you may have an ectopic pregnancy. This means that the pregnancy is not in the uterus. Unusual vaginal bleeding or abdominal pain 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 Kyleena 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 Kyleena, even though removing it may cause a miscarriage. If Kyleena cannot be removed, talk with your healthcare professional about the benefits and risks of continuing the pregnancy and possible effects of the hormone on your unborn baby. 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.

1,826 daily pills over 5 years versus 1 Kyleena® IUD

Kyleena 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.† 


Kyleena lasts up to 5 years, and eliminates the responsibility of taking a daily pill—that’s 1,826 daily pills over 5 years vs 1 Kyleena IUD. Monthly pharmacy trips for birth control refills are a thing of the past! But, you will need to do a thread check once a month to make sure Kyleena is still in place. Your healthcare professional can show 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. Kyleena may not be in the right position and may not prevent pregnancy. Avoid intercourse or use non-hormonal back-up birth control (such as condoms or spermicide) until your healthcare professional can check that Kyleena 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.

Kyleena® (levonorgestrel-releasing intrauterine system) is a hormone-releasing IUD that prevents pregnancy for up to 5 years.



  • If you have a pelvic or genital infection, get infections easily, or have certain cancers, don't use Kyleena. Less than 1% of users get a serious pelvic infection called pelvic inflammatory disease (PID).
  • If you have persistent pelvic or stomach pain, or excessive bleeding after placement tell your healthcare provider (HCP). If Kyleena comes out, call your HCP and avoid intercourse or use non-hormonal back-up birth control (such as condoms or spermicide). Kyleena may go into or through the wall of the uterus and cause other problems.
  • Pregnancy while using Kyleena 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.


Kyleena does not protect against HIV or STIs.


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