Mirena Uses

Mirena is an intrauterine device that is used for preventing pregnancy. This contraceptive is specifically designed for women who have already had at least one baby, desire long-term birth control, and are in a mutually monogamous relationship. Mirena works by slowly releasing a hormone, which can stop ovulation, alter the cervical mucus, and change the lining of the uterus. There are currently no off-label Mirena uses.

 

What Is Mirena Used For?

Mirena® is an intrauterine contraceptive (IUC) that is used for long-term pregnancy prevention. It is a small, flexible plastic device that contains levonorgestrel (a progesterone hormone). It works for five years, although your healthcare provider can remove it earlier if you desire.
 
Mirena is not for everyone. Mirena is designed for women who:
 
  • Have already had at least one baby
  • Desire long-term birth control
  • Are in a stable, mutually monogamous relationship (this means that neither you nor your partner have other sexual partners).
     
Mirena is very effective at preventing pregnancy. Only 0.1 percent of women will become pregnant while taking Mirena. This is at least as effective as the birth control pill and much more effective than most other forms of birth control. Mirena is not a permanent form of contraception. After it is removed, 80 percent of women may become pregnant within one year.
 
It's also important to note that Mirena does not protect against HIV or other sexually transmitted diseases (STDs).
