The Mirena intrauterine device (IUD) is often used to help manage heavy menstrual bleeding. It’s a small, T-shaped device that’s placed inside the uterus and releases a hormone called levonorgestrel, a type of progestin. This hormone works to:
- Thin the uterine lining: This can reduce the amount of menstrual bleeding.
- Reduce cramping and pain: It can also help with any pain or cramping associated with periods.
- Regulate periods: Over time, many women experience lighter periods or even stop having periods altogether.
In fact, the Mirena IUD is approved by the FDA for the treatment of heavy menstrual bleeding in women who wish to avoid other surgical options like a hysterectomy. The IUD is typically recommended when other methods of managing heavy bleeding (such as medications or non-hormonal IUDs) haven’t been effective.
It is highly effective, with most users experiencing significant reduction in bleeding within the first 3 to 6 months of use. Very minimal side effects like spotting, mood changes and breast tenderness may be experienced. The greatest advantage is that it is locally acting within the uterus for a period of 5 years after which it has to be replaced with a new one. Insertion of Mirena just requires a few minutes and can be done as an OPD procedure or with minimal sedation.
The Mirena IUD, in addition to being used for managing heavy menstrual bleeding, has several other medical uses. Here are some of the other common and approved uses:
- Contraception:
- Mirena is primarily used as a form of long-term contraception. It is more than 99% effective in preventing pregnancy for up to 5 years. The IUD releases a low dose of the hormone levonorgestrel, which thickens cervical mucus to prevent sperm from reaching the egg, and can also prevent ovulation in some cases.
- Endometrial Protection during Estrogen Therapy:
- For women who are undergoing estrogen replacement therapy (often for menopause symptoms), Mirena can be used to protect the lining of the uterus from becoming too thick (which can be a risk when using estrogen alone). The hormone in the Mirena helps prevent endometrial hyperplasia (a condition where the lining of the uterus becomes too thick).
- Management of Endometriosis:
- Mirena can be used to help manage endometriosis symptoms, which can include severe menstrual pain. The progestin hormone in the IUD can reduce the growth of endometrial tissue outside the uterus, providing relief from pain and heavy bleeding associated with endometriosis.
- Treatment of Adenomyosis:
- Adenomyosis is a condition where the tissue that normally lines the uterus grows into the muscular walls of the uterus, causing heavy menstrual bleeding and pelvic pain. Mirena can help manage these symptoms by thinning the uterine lining and reducing bleeding.
- Treatment for Dysmenorrhea (Painful Periods):
- For women who experience severe pain with their periods (dysmenorrhea), the Mirena IUD can help by reducing the bleeding and cramping associated with menstruation. This is often a benefit for those with conditions like endometriosis or fibroids.
- Prevention of Pregnancy in Women with High Risk for Pregnancy:
- Mirena can be a good option for women who have contraindications for using other forms of birth control, like those who cannot take oral contraceptives due to medical conditions (e.g., blood clot risk).
While Mirena is quite effective for these purposes, it’s important to talk to a healthcare provider to determine if it’s the right choice for your specific needs and health profile. The only absolute contraindication for Mirena is history of breast cancer. Millions of women worldwide have benefitted from the use of Mirena and have a control over their reproductive health.
