A new study has found that women who are at an increased risk of rheumatoid arthritis (RA) could elevate risks of developing RA if they use intrauterine devices such as the Mirena IUD. The study found that oral contraceptives reduced body levels of an arthritis-inducing serum known as ACPA, while an IUD birth control device increased those levels.
Adjusted for all outside factors, IUD users had more than twice the increased risk of elevated ACPA levels as other forms of birth control. The study is another in a line of research that indicates birth control devices, such as the Mirena IUD, could carry potentially severe side effects.
Thousands of women have filed Mirena IUD lawsuits against manufacturer Bayer Pharmaceuticals alleging that the device carries risks of severe complications. Mirena side effects include internal bleeding, ectopic pregnancy, and tissue damage when the device perforates the uterus and travels to other parts of the body.
