Mirena® is a soft, flexible, estrogen-free intrauterine contraceptive (IUC) that can be effective for up to five years. It is a tiny T-shaped piece of plastic implanted into the uterus to block sperm and make the uterine lining thinner.
Mirena is effective in preventing pregnancy without the side effects of a birth control pill. If you want to have children, you can try to become pregnant as soon as the device is removed. Within a year of removal, most women are able to succeed in becoming pregnant.
For those women who have heavy periods, Mirena has been shown to reduce menstrual flow. If you have a tendency to develop pelvic infections or have certain cancers, Mirena may not be the right choice for you.
Talk to your doctor about the contraception choices available that are best for you.
