Warfarin

Warfarin is an anticoagulant medication used to prevent blood clots, reducing the risk of stroke, heart attack, and deep vein thrombosis. It works by inhibiting vitamin K activity, crucial for blood clotting, thus thinning the blood. Commonly prescribed in hospitals and for at-home treatment, warfarin requires regular INR monitoring to ensure proper dosage and efficacy. Essential for patients with atrial fibrillation, it helps maintain cardiovascular health and prevent complications.
