Get to know the Mirena® IUD

Choosing birth control is personal, and for women who want to prevent pregnancy—while also needing help with heavy periods—it’s important to know there is an option that does both. If you’re considering an IUD (intrauterine device) but also struggle with heavy periods, get to know Mirena:

 

  • Over 99% effective at preventing pregnancy for up to 8 years

  • The first and only hormone-releasing IUD that is FDA-approved to treat heavy periods—also known as heavy menstrual bleeding (HMB) —for up to 5 years in women who choose an IUD for birth control

  • Can be used whether or not you’ve had a baby

  • Can be removed by your healthcare provider anytime in case your plans change

 

Who should not use Mirena?

Mirena is not right for everyone. Do not use Mirena if you:

 

  • are or might be pregnant; Mirena cannot be used as an emergency contraceptive

  • have a serious pelvic infection called pelvic inflammatory disease (PID) or have had PID in the past unless you have had a normal pregnancy after the infection went away

  • have an untreated genital infection now

  • have had a serious pelvic infection in the past 3 months after a pregnancy

  • can get infections easily. For example, if you:

    • have multiple sexual partners or your partner has multiple sexual partners

    • have problems with your immune system

    • use or abuse intravenous drugs

  • have or suspect you might have cancer of the uterus or cervix

  • have bleeding from the vagina that has not been explained

  • have liver disease or a liver tumor

  • have breast cancer or any other cancer that is sensitive to progestin (a female hormone), now or in the past

  • have an intrauterine device in your uterus already

  • have a condition of the uterus that changes the shape of the uterine cavity, such as large fibroid tumors

  • are allergic to levonorgestrel, silicone, polyethylene, silica, barium sulfate or iron oxide
