Mirena IUD Birth Control Method

What is a Mirena® IUD?

Mirena is an intrauterine device (IUD) used for birth control.  Made of soft, flexible plastic, it is inserted in the uterus by the doctors at Women’s Health Wise during a short office visit. Mirena is effective for up to 5 years but can be removed earlier.  Mirena works by slowly releasing very small amounts of the hormone levonorgestrel directly into your uterus which has several contraceptive effects. (See diagram below) It offers a highly effective, convenient, reversible, estrogen free method of birth control that works continuously without having to take a pill everyday.

What the Mirena IUD does:

  • Mirena is over 99% effective, and is among the most effective forms of reversible birth control available today!
  • When you decide to have the Mirena removed, the contraceptive effect withdraws quickly and you will return to fertility within a few months.
  • The Mirena IUD is FDA Approved to treat heavy periods. In a clinical trial, the majority of women with heavy periods treated with Mirena showed a reduction in bleeding of more than 90% at 6 months.

How does the Mirena IUD work?

Text says Mirena prevents pregnancy most likely in several ways (highlighted in teal in the graphic) Mirena may stop the release of your egg from your ovary, but this is not the way it works on most cases. Most likely the different actions work together to prevent pregnancy. Mirena is placed in the uterus not the vagina so neither you nor your partner should be able to feel it during sex. Sometimes male partners may feel the threads.  Mirena inhibits sperm from reaching/fertilizing egg; thins uterine lining; thickens cervical mucus to prevent sperm from entering uterus. Two threads are attached to the stem of Mirena that help insure that it remains properly placed. These threads are the only part you should be able to feel when Mirena is positioned correctly. Your Healthcare provider can explain how to check them.

Is a Mirena IUD Right for You?

  • The Mirena IUD is an effective birth control option for most women. During your office visit, we will discuss your particular circumstances and help you decide whether a Mirena IUD is the best option for you. For example:
    • You just had a baby and are nursing, Mirena offers a safe birth control option
    • You may want to have more children in the future but do not know when and you need a reversible form of birth control.
    • You are happy with your current family size but you are not ready for permanent sterilization
    • You want birth control without a daily routine or hassle

Mirena Safety Considerations

  • Once we have properly placed the device, we will show you how to check the threads once a month. If you have trouble finding the threads, be sure to switch to a backup form of birth control and call our office to make an appointment. 
  • Do not use Mirena if you have a pelvic infection
  • The Mirena IUD does NOT protect against sexually transmitted diseases
  • Share your health history with your healthcare provider before placement
  • There are some serious but uncommon side effects associated with Mirena
  • Review possible common side effects of Mirena after placement
  • Although uncommon, pregnancy while using Mirena can be life threatening and may result in loss of pregnancy or fertility
