Warfarin is effective in preventing strokes and other blood clots in patients with A-Fib. But there are some challenges with warfarin therapy. Warfarin interacts with some foods and several other drugs. Too much warfarin can put a patient at risk for bleeding. Too little warfarin can result in a stroke or other blood clot. Finding the perfect warfarin balance can be tricky, and requires different dosing strategies for different patients. Frequent blood tests to monitor warfarin therapy are required. Most patients with A-Fib taking warfarin are followed by their family doctor (usual care), but some are seen in specialized anticoagulation clinics, while others may manage their own warfarin therapy. But how is warfarin therapy best managed to get the greatest possible benefit from the drug?
