Mirena®
is a hormone-releasing intrauterine contraceptive that
provides up to five years of 99.9% effective birth control
without the permanence of surgery.
Mirena® is an Intrauterine System or IUS.
It is a small T-shaped device like the IUD and
is placed inside the uterus by a health care provider.
It releases a small amount of a hormone each day to keep
you from getting pregnant.
It
does not protect against STDs or HIV. The Food and Drug
Administration approved this method in December 2000.
In clinical studies, the most common side effects with
Mirena® included:
Menstrual changes
Lower abdominal pain (cramps)
Acne or other skin problems
Back pain
Breast tenderness
Headache
Mood changes
Nausea
Ovarian
cysts have been diagnosed in about 12% of Mirena users.
In most cases, these cysts disappeared spontaneously during
2 to 3 months' observation. Women who have, or have had,
breast cancer should not use hormonal therapy.
