Mirena Works For Up To 8 Years

Article Media

IUD stands for intrauterine device. They are small plastic “t” shaped devices that are inserted by a doctor or health care provider into the uterus to prevent pregnancy. The Mirena IUD uses hormones to protect against pregnancy. Mirena had previously been approved to prevent pregnancy for up to 7 years but based on new research, it is now approved for 8 years but you can always have it removed sooner by a doctor or health care provider.

Why did they extend the effectiveness of Mirena?

After Mirena was approved for use, they continued to study the IUD. Based on a study where people who were using Mirena continued to use it past 8 years, researchers could see that it continued to be effective at preventing pregnancy. The data from this study was submitted to the FDA who approved the birth control method for this extended use.

How do IUDs work?

All types of IUDs change the environment in the uterus and make it harder for sperm to reach an egg. IUDs are inserted inside the uterus by a doctor or health care provider during a simple procedure that only takes a few minutes. Mirena (and other IUDs including Sykla, Liletta, and Kyleena) have a small amount of hormones in them.  The One type of IUD, the ParaGuard, has no hormones in it and is wrapped in copper. IUDs also have a string attached to them that will come through the cervix and stay in the vagina. Sometimes doctors will ask you to check for your strings once a month.

How effective are IUDs?

All types of IUDs are over 99% effective at preventing pregnancy once they are inserted until they are removed or until they reach the length of time they are designed to last. Think of it like an expiration date. If someone has an IUD for as long as it lasts, they should have it removed by a doctor or healthcare provider. Then they can choose to get another IUD or find a different method of birth control. But remember, IUDs do NOT protect against STIs. Using a condom with an IUD will help protect against STIs and pregnancy. You can find free condoms near you!
