You should do a monthly thread check to make sure it's in place—ask your healthcare provider to explain how
Placement of Mirena is nonsurgical
Reversible, so you can have it removed at any time and try to become pregnant right away. Placement takes only a few minutes
Everyone is different, and some women may experience discomfort, dizziness, or spotting during and after placement. These symptoms should go away shortly. If they don’t, contact your healthcare provider, as Mirena may not have been properly placed. Within 4 to 6 weeks, you should return for a follow-up visit to make sure that everything is okay.
Mirena is an intrauterine device (also known as an IUD) that releases small amounts of the hormone levonorgestrel locally into your uterus. Made of soft, flexible plastic, Mirena is placed by your healthcare provider during an office visit. Mirena can be used whether or not you have had a child.
- Mirena offers contraception that's over 99% effective; in fact, it is one of the most effective methods of reversible birth control
- Mirena prevents pregnancy for as long as you want, for up to 5 years
- You can try to become pregnant as soon as Mirena is removed by your healthcare provider. In fact, about 8 out of 10 women succeed at becoming pregnant within 1 year of having Mirena removed
How does Mirena work to prevent pregnancy?
Mirena is an IUD that releases small amounts of a progestin hormone called levonorgestrel into the uterus.
Mirena may work in several ways:
Is the Mirena FDA approved?
Mirena was approved by the FDA for use in the United States in 2000 for intrauterine contraception and in 2009 to treat heavy periods for women who choose intrauterine contraception. Discuss all safety considerations with your healthcare provider and use Mirena according to the Prescribing Information. No birth control is right for everyone and there are always risks that you should know about. Have a conversation with Dr Yande to find out if Mirena is right for you.
What about Hormones and Mirena?
Mirena contains a progestin hormone called levonorgestrel that is often used in birth control pills. Because Mirena releases levonorgestrel into your uterus, only small amounts of the hormone enter your blood. Mirena does not contain estrogen.
What happens if I become pregnant while using the Mirena?
One risk of becoming pregnant while using Mirena is called ectopic pregnancy. This means that the pregnancy is not in the uterus. It may occur in the fallopian tubes. Signs of ectopic pregnancy may include unusual vaginal bleeding or abdominal pain. Ectopic pregnancy is an emergency that requires immediate medical attention and often requires surgery. Ectopic pregnancy can cause internal bleeding, infertility and even death, so it is important to call your healthcare provider right away if you think that you're pregnant.
There are also risks if you become pregnant while using Mirena and the pregnancy is in the uterus. Severe infection, miscarriage, premature delivery and even death can occur with pregnancies that continue with an intrauterine device (IUD). Because of this, your healthcare provider may try to remove Mirena, even though removing it may cause a miscarriage. If Mirena cannot be removed, talk with your healthcare provider about the benefits and risks of continuing the pregnancy.
If you continue your pregnancy, see your healthcare provider regularly. Call your healthcare provider right away if you get flu-like symptoms, fever, chills, cramping, pain, bleeding, vaginal discharge, or fluid leaking from your vagina. These may be signs of infection.
It is not known if Mirena can cause long-term effects on the fetus if it stays in place during a pregnancy.
