Taking the blood thinner warfarin at the same time as certain diabetes drugs increases the risk of hospitalization, a study from the University of Southern California warns. Researchers analyzed data from nearly 466,000 Medicare patients. They found that those who took warfarin along with the diabetes drugs glipizide or glimepiride — also known as sulfonylureas — had a 22% increased risk of making an emergency room visit or being hospitalized for low blood sugar (hypoglycemia).
