Mirena is one of the most effective low-maintenance birth control options. Once Mirena is placed by your healthcare provider, it is over 99% effective and works consistently to prevent pregnancy for as long as you want, for up to 5 years.
As the chart on this page shows, when choosing birth control, generally the more you have to do the less effective the option. The most effective methods, including intrauterine devices such as Mirena, are found at the top of the chart. If you think Mirena may be right for you, review this list of questions and have a conversation with your healthcare provider.
Birth control without a daily routine
Mirena (levonorgestrel-releasing intrauterine system) is birth control you don’t have to think about every day or even every year. Once it’s placed, check the threads of Mirena once a month to make sure it’s in the correct position. Your healthcare provider can explain how.
Birth control that gives you flexibility to change your mind
Birth control should give you options if you’re not sure you want more children. With Mirena, you get both efficacy and flexibility. Mirena lasts for as long as you want, for up to 5 years, and can be removed by your healthcare provider at any time, so you can try to become pregnant right away. Within a year of having Mirena removed, about 8 out of 10 women succeed at becoming pregnant.
