Yes. Approximately 1,000 serious adverse incidents have been reported to the FDA by women using NuvaRing and their doctors. Reported problems include:

• Blood clots
• Deep Vein Thrombosis (DVT)
• Heart attack
• Heart arrhythmia

• Stroke
• Pulmonary embolism
• Liver cancer
• Gallbladder disease

A particularly poignant case was described in an article in Marie Claire magazine, where a 26-year-old woman developed life-threatening blood clots linked to NuvaRing use.
