Mirena is intrauterine birth control that’s over 99% effective at preventing pregnancy. It’s made of soft, flexible plastic and placed into your uterus by your healthcare provider during a routine office visit. Mirena releases small amounts of hormone directly into the uterus and lasts as long as YOU want, for up to 5 years. It is important to note that Mirena is recommended for women who have had a child. Mirena does not protect against HIV or STDs.
Mirena is a small, flexible hormone-releasing device inserted into the uterus to prevent pregnancy. The female hormone released by the device, levonorgestrel, thickens the cervical mucus to prevent sperm from reaching or fertilizing the egg.
