Mirena IUD linked to increased breast cancer risk in premenopausal women

Premenopausal women who use a hormone-releasing intrauterine device, such as the Mirena IUD, are at greater risk of developing breast cancer, according to a study recently published in the journal Obstetrics & Gynecology. There are three IUDs marketed in the United States – the ParaGard, Mirena and Skyla. Only Mirena and Skyla, which are both made by Bayer Healthcare, contain a small amount of the levonorgestrel, a synthetic form of the hormone progestin. IUDs are used to prevent pregnancy, but levonorgestrel-releasing IUDs can reduce heavy bleeding and are often given to women to help treat heavy periods, a condition known ... Read More

Lawsuits against Bayer alleging neurological side effects from Mirena IUD will not be centralized

Nine lawsuits against Bayer Healthcare Pharmaceuticals alleging the company’s Mirena IUD caused neurological conditions will not be consolidated into a multidistrict litigation because there are just too few to justify the motion. Plaintiffs had asked that the lawsuits be centralized in Tennessee; Bayer opposed centralization or to have them consolidated in New York. Bayer already faces multidistrict litigation with its Mirena intrauterine device over uterine perforation, a different injury. These nine lawsuits claim that the Mirena IUD contraceptive device releases a synthetic hormone that can cause neurological problems, including a type of brain damage known as pseudo tumor cerebra (PTC) ...

New study links certain IUDs to breast cancer

A recent study from the Journal of Obstetrics and Gynecology has shown that levonorgestrel-releasing intrauterine system (LNG-IUS) or progesterone-releasing intrauterine device (IUD), may be associated with a higher than expected incidence of breast cancer. These hormones are used to treat women who suffer from heavy periods, endometriosis and chronic pelvic pain; and as a contraceptive. Levonorgestrel is a synthetic progesterone, which helps to regulate ovulation. It helps strengthen the uterine wall to control the bleeding, which also makes it more difficult for the sperm to get through, making it harder to conceive. This is the same hormone that is used ...

IUD effectiveness may last longer than advertised

Intrauterine devices, or IUDs, may be effective at preventing pregnancy longer than advertised, according to a new review of several studies. IUDs are small, T-shaped devices that are inserted into the cervix to prevent pregnancy by either killing or damaging sperm, or by releasing hormones that thicken the cervical mucus and prevent sperm from passing. They are considered the most effective type of reversible contraception compared to birth control pills, implants, patches or condoms. Two types of IUDs sold in the United States include the ParaGard, a copper IUD, and the Mirena, a plastic device that releases the hormone levonorgestrel. ... Read More

Bayer markets Mirena-like IUD for adolescents despite Mirena IUD injury lawsuits

A new intrauterine device is being marketed in the United States with sexually active adolescents in mind. Skyla, made by Bayer Healthcare, is raising concerns among some experts not because it is geared toward younger women, but because some IUDs, especially the Mirena, also made by Bayer, have been associated with injuries, some of which have been serious. Skyla is a new version of Bayer’s Mirena. Both deliver a steady dose of the hormone levonorgestrel, but Skyla is smaller than the Mirena, lasts up to three years as opposed to five years with Mirena, and contains less of the hormone ...

Serious injuries associated with Mirena IUD

Women who are using the intrauterine device Mirena should be aware that the IUD could spontaneously migrate after it is inserted, and may cause serious injury, The Safety Report warns. The Mirena IUD is a birth control device that is also used to treat heavy menstrual bleeding. It is a small, T-shaped device made of flexible plastic that is inserted into the uterine cavity by a trained health care provider. The IUD releases the hormone levonorgestrel to prevent pregnancy. Since the Mirena IUD was approved in 2000, the Food and Drug Administration (FDA) has received numerous reports of adverse events ... Read More

Woman suffers toxic shock from IUD

“I got toxic shock from an IUD,” writes Alice Myerhoff on XO Jane. It was a rare side effect even the hospital had a hard time believing. But Myerhoff easily saw the connection. A few days after she received an intrauterine device for pregnancy protection she became deathly ill. She called her nurse, who brushed off her symptoms, which included fever and body shakes. It wasn’t until she developed a suspicious red spot on her leg and had difficulty walking on it that the nurse ordered her to see her doctor right away. She was then taken to the emergency ...

Tens of thousands of adverse events associated with Mirena IUD

The Mirena Intrauterine Device (IUD) has been associated with more than 47,000 adverse event reports since the device was introduced in 2000, according to AdverseEvents.

It is also used to control heavy menstrual bleeding in women who use IUDs for contraception. The device releases the hormone levonorgestrel. From the time the device hit the market through August 27, 2012, there have been 47,218 reports of a serious adverse event where the Mirena IUD was identified as the primary culprit. ... Read More

FDA approves over-the-counter sales of morning after pill to women age 15 and older

Plan B One-Step contains ... Read More

Two drugs have little effect on shortening duration of bleeding after IUD insertion

Neither a drug used to prevent or treat excessive bleeding during surgical procedures or a non-steroidal anti-inflammatory drug (NSAID) used to treat menstrual pain were able to alleviate bleeding or spotting during the first 90 days after placement of a hormone-releasing intrauterine device, or IUD, according to a study online published this month in the journal Obstetrics & Gynecology. The study aimed to identify a 25 percent reduction in the number of bleeding or spotting days for the first three months after insertion of an IUD that released the hormone levonorgestrel. The only intrauterine device that releases levonorgestrel approved for ... Read More
