Two view points on warfarin
Available since the 50s, warfarin has become the most prescribed anticoagulant in the world. A patient and a doctor have given their perspectives to Judy O’Sullivan.
Warfarin acts by increasing the time blood takes to clot. Warfarin is prescribed to patients who have atrial fibrillation (which is one of the most common forms of irregular heart rhythm) in order to reduce the risk of stroke, patients with a variety of clotting disorders such as deep vein thrombosis or pulmonary embolism, which is a blood clot in the lung, and to people who have had a replacement metal heart valve.
Levels of warfarin in the bloodstream can vary over time, so regular blood tests are needed to ensure the dose prescribed is safe and effective.
