Two recent news stories shed more light on the anticoagulant Xarelto, the risks those who use it face and the problems that arose during a study comparing it to an older drug, warfarin. Xarelto is the subject of lawsuits by some users and surviving family members of users whose deaths may be related to the drug. The legal claims are largely based on incidents of uncontrolled bleeding that caused serious injuries or deaths.
People with an abnormal heartbeat known as atrial fibrillation who use Xarelto may be running a slightly greater chance of serious bleeding compared to those using the competing anticoagulant Pradaxa, according to WebMD. Many patients with atrial fibrillation use an anticoagulant to lessen the chance of suffering a stroke. Their downside is a risk of potentially fatal, uncontrollable bleeding.
