Warfarin sodium, often referred to by brand names like Coumadin and Jantoven, is a medication classified as an anticoagulant. While it's commonly called a "blood thinner," it doesn't actually reduce the viscosity of blood. Instead, it works by inhibiting the production of certain proteins in the blood that are necessary for clotting. This can help prevent blood clots from forming or growing larger in the blood vessels.
Here's a summary of Warfarin sodium:
- Uses: Treat and prevent blood clots, reducing the risk of stroke, heart attack, and pulmonary embolism.
- Mechanism of action: Blocks the production of vitamin K-dependent clotting factors.
- Dosage: Usually taken once a day in tablet form, with or without food. The exact dosage will depend on individual factors and requires regular monitoring through blood tests.
- Side effects: Increased risk of bleeding, nausea, vomiting, hair loss.
Important to note:
- Warfarin interacts with many foods, supplements, and medications, so it's crucial to inform your doctor about everything you're taking before starting Warfarin therapy.
- Due to the increased bleeding risk, people on Warfarin may need to be cautious with activities that could cause injury.
- Regular blood tests are essential to monitor clotting time (INR) and ensure the medication is working effectively.
