The FDA has received more than 1,000 reports of NuvaRing-related blood clots. More than 700 women are currently suing Merck, the drug company that manufacturers NuvaRing, for downplaying the serious risks that the birth control method holds.
Consumer group Public Citizen has petitioned the FDA to ban NuvaRing however the FDA has not taken any action so far.
The FDA mandated in 2005 that the manufacturers change NuvaRings warning label to include information about irregular bleeding associated with Nuvaring use, interactions with other drugs, increased risk of toxic shock syndrome, and that women with a history of heart disease, blood clots or hypertension should not use NuvaRing due to the increased risk of serious side effects.
The FDA again ordered the manufacturer in 2008 to update the NuvaRing warning label to include more detailed instructions about how to insert and remove the NuvaRing. After an FDA-ordered warning, the NuvaRing labeling also warns of an increased risk of serious cardiovascular side effects in women who smoke, particularly those over age 35 or who smoke 15 or more cigarettes a day.
