Does Warfarin Increase the Risk of Bone Fractures in Older Adults?
Dr. Kumar’s Take:
This large study of older adults with atrial fibrillation found that long-term use of warfarin—a common blood thinner—was linked to a higher risk of fractures, especially in men. Warfarin blocks vitamin K2, which is essential for strong bones. If you or a loved one is on warfarin for over a year, it may be worth discussing fracture prevention with your doctor. This could include reviewing your diet, checking vitamin D levels, or considering alternative anticoagulants that don’t affect bone health.
