A Nuvaring lawsuit has been filed by the estate of a Nebraska woman who allegedly died due to a blood clot in one of her lungs that was caused by complications of the vaginal birth control ring. NuvaRing birth control is inserted once a month and releases etonogestrel and ethinyl estradiol to prevent unwanted pregnancy. The lawsuit indicates that Tompkins, of Omaha, died in February 2009 after using the device for only five months, alleging that the drug makers failed to adequately warn about the risk of problems from NuvaRing. An autopsy determined that Tompkins died due to a blood clot that had traveled to her lung, a condition known as a pulmonary embolism. The Nuvaring wrongful death lawsuit seeks an unspecified amount of damages for the death, lost wages, and funeral expenses, and also is requesting punitive damages be levied against the defendants.
