Why should you consider Mirena®?

See more children in your future but aren’t ready yet? Or maybe your family is just the right size but you’re not ready for permanent birth control. Either way, Mirena might be right for you if you want birth control that is:

Highly effective—One of the most effective birth control methods—over 99% at preventing pregnancy for up to 6 years

Approved to treat heavy periods—Mirena is the first and only IUD (intrauterine device) birth control that is FDA-approved to treat heavy periods for up to 5 years, in women who choose intrauterine birth control

Low-maintenance—No daily pills and no monthly refills. You should do a monthly thread check to make sure it’s in place. Ask your healthcare provider to explain how. You should schedule a follow-up visit 4 to 6 weeks after your Mirena is placed to check that it’s in the right position

Reversible—You can have it removed by your healthcare provider at any time, and try to become pregnant right away

Estrogen-free—It delivers small amounts of progestin locally into your uterus

Mirena does not protect against HIV or STIs (sexually transmitted infections).

If you have any questions about Mirena, have a conversation with your healthcare provider, who can help you decide which birth control option is best for you.

For additional information about Mirena, including side effects, please see Mirena Safety Considerations and the Patient Information.

Because Mirena releases hormones locally in the uterus at a slow rate, only small amounts enter the blood.
