Is Coumadin the Best Anticoagulant for Stroke Prevention in AFib?

Anticoagulant medications are a necessary part in drug treatment for atrial fibrillation, because an AFib patient is at very high risk of having a stroke. The most common blood thinner is warfarin, which is also known by its brand name Coumadin. Well, “most common” means that many patients can take it, but it is not necessarily the best choice for you. Some AFib patients even can’t take any anticoagulant, let alone Coumadin.

There are some risks in taking Coumadin. Patients on Coumadin are at increased risk of bone fracture. And other side effects include dizziness, headaches, and skin necrosis which is very rarely. The biggest disadvantage of taking Coumadin is that it may cause bleeding. The US Food and Drug Administration (FDA) has issued a black box warning that warfarin (Coumadin®) poses a serious and significant health risk due to the potential for major, or even fatal, bleeding.
