Balancing bleeding vs. stroke risk when you have atrial fibrillation
Careful compliance makes management of anticoagulant and antiplatelet drugs safer.
If you have atrial fibrillation and have been prescribed an anticoagulant such as warfarin (Coumadin), there may come a time when your doctor will consider adding another type of blood thinner, called an antiplatelet agent, to your anti-clotting regimen. Examples of antiplatelet agents include aspirin, clopidogrel (Plavix), and prasugrel (Effient).
Each kind of blood thinner paralyzes a different part of the blood-clotting process. Taking them together doubles your risk of a dangerous hemorrhage. But some people need both kinds of blood thinners because they are at high risk of blood clots—which can lead to the most common kind of stroke.
