Mirena®

Mirena (levonorgestrel-releasing intrauterine system) is an intrauterine contraceptive that delivers small amounts of hormone directly to the uterus.

Made of soft, flexible plastic, it is put in place by your healthcare provider during an office visit. Mirena is birth control that lasts as long as you want, for up to 5 years, and is also approved to treat heavy periods in women who choose intrauterine contraception. Mirena works continuously, without having to take a pill, without a daily hassle.

Once Mirena is properly placed, all you have to do is check the threads once a month. Your healthcare provider can show you how. If you have trouble finding the threads, be sure to use a backup form of birth control and call your healthcare provider.

What Mirena does:

  • Offers an over 99% effective form of contraception, among the most effective forms of birth control
  • Prevents pregnancy for as long as you want, for up to 5 years Allows you to try to become pregnant as soon as it is removed by your healthcare provider.*
  • Treats heavy periods: In a clinical trial of women with heavy periods, the majority treated with Mirena showed a reduction in bleeding of more than 90% at 6 months.
