Warfarin is a medication commonly prescribed as an anticoagulant, often referred to as a blood thinner. It is used to prevent and treat blood clots in various conditions, including deep vein thrombosis, pulmonary embolism, and atrial fibrillation. Warfarin works by interfering with the body's natural clotting process, specifically by inhibiting the action of vitamin K, which is essential for the synthesis of certain clotting factors.

The dosage of warfarin is highly individualized and requires careful monitoring. This is typically done through regular blood tests, most commonly the International Normalized Ratio (INR), which measures how long it takes for blood to clot. Maintaining the INR within a specific therapeutic range is crucial to ensure the medication is effective while minimizing the risk of bleeding.

Because of its mechanism of action, warfarin carries a significant risk of bleeding. Patients taking warfarin must be cautious about activities that could lead to injury and should inform any healthcare provider they see that they are taking this medication. Interactions with other medications, foods rich in vitamin K, and certain herbal supplements can affect warfarin's efficacy and increase bleeding risk. Therefore, a comprehensive discussion with a healthcare professional is essential before starting warfarin therapy.
