Bayer Sued Over Alleged Hidden Risks of Mirena Contraceptive

Bayer AG was sued over claims the German drugmaker failed to provide disclosures and warnings regarding the health risks associated with its popular contraceptive Mirena.

The label for Mirena, an intrauterine device that prevents pregnancy for as long as five years, doesn’t warn that it can can become embedded in the body or cause an ectopic pregnancy, Pennsylvania resident Tricia Prendergast said in a complaint filed in federal court in Philadelphia. Prendergast required surgery to remove the device after complications, according to her complaint.
