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.
