Amid Lawsuits, Experts Caution More Research Into IUDs Causing Neurological Disorder

“Over the past two years, 856 people have filed lawsuits against German drug company Bayer, claiming that the popular IUD Mirena is causing neurological side effects, Rewire reports. Experts who have been following the case, however, say that more research is needed before a connection can be made between the contraceptive and the disorder addressed in the complaint.”

“That complaint lodged in this most recent set of lawsuits pertains to something that is not listed on the label: a neurological disorder that falsely resembles a tumor. The disorder is known as pseudotumor cerebri, or idiopathic intracranial hypertension — a fancy way to say increased pressure on the brain. The Mayo Clinic lists symptoms of the condition as including headaches, worsening vision, tinnitus, ringing in the ears, and nausea. At present, the cause of the disorder is unknown, though factors like obesity, some medications, and various health problems are among the risk factors.”
