What is Mirena®?

Imagine having hassle-free birth control for up to 5 years (or less, if you choose).1 Birth control that, once removed, allows you to try to become pregnant right away and adapts to your contraceptive needs throughout the different stages of your life. That's Mirena®, an estrogen-free intrauterine contraceptive that delivers small amounts of hormone directly to the uterus. Other benefits of Mirena®:

  • 99.8% effective in preventing pregnancy for up to 5 years (or less, if you choose)1
  • Provides lower and steadier hormones than the Pill
  • Won't cause significant weight gain2
  • Easily removed with quick return to fertility1
  • May also help shorten, lighten or even eliminate periods3

IMPORTANT INFORMATION ABOUT MIRENA®:
Only you and your healthcare professional can decide if Mirena is right for you. Mirena does not protect against HIV or sexually transmitted diseases (STDs). Candidates for Mirena have had a child. Mirena is not appropriate for women who are or may be pregnant; or who may have a distorted uterine cavity; acute genital infections including pelvic inflammatory disease; cancer of the cervix, uterus, or breasts; unexplained vaginal bleeding; or acute liver disease or tumors (benign or malignant). In rare cases, perforation or embedment may occur. Mirena may become completely or partially dislodged. In the rare event you think you're pregnant, contact your healthcare professional without delay to be evaluated for ectopic pregnancy. Ovarian cysts may occur and typically disappear. Persistent cysts should be evaluated. Missing periods or irregular bleeding is common in the first few months, followed by shorter, lighter periods.

You are encouraged to report negative side effects of prescription drugs to the FDA.
Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
