Study Shows Increased Bleeding Risks after Taking Blood-Thinner Pradaxa

Over the last 4 years, robust testing of the drug Pradaxa’s effectiveness has uncovered an increased risk in bleeding, sometimes resulting in death. A study done by University of Pittsburgh and reported online in the journal of JAMA Internal Medicine (Article Here) surveyed 9,400 men and women who had atrial fibrillation—1,300 of whom were given Pradaxa and 8,100 of whom were given warfarin. The study concluded that “[Pradaxa] was consistently associated with an increased risk of major bleeding and gastrointestinal hemorrhage for all subgroups analyzed. The risk of major bleeding among [Pradaxa] users was especially high for African Americans and patients with chronic kidney disease.”
