How does Mirena® look?

Mirena is a small, flexible, plastic, T-shaped IUD (intrauterine device)

Mirena® placement in woman's body

Mirena is placed in the
uterus by a healthcare
provider during an
office visit and takes only
a few minutes

You may experience pain, bleeding or dizziness during and after placement. If your symptoms do not pass within 30 minutes after placement, Mirena may not have been placed correctly. Your healthcare provider will examine you to see if Mirena needs to be removed or replaced.

You and your partner should not feel Mirena during intercourse. Mirena is placed in the uterus, not in the vagina. Sometimes your partner feels the threads. If this occurs, talk with your healthcare provider.

If you ever have trouble finding the threads or feel more than just the threads, Mirena may not be in the right position and may not prevent pregnancy. Use nonhormonal back-up birth control (such as condoms and spermicide) and ask your healthcare provider to check that Mirena is still in the right place.
