Warfarin 5mg

Warfarin 5mg Uses

Warfarin 5mg is prescribed to:

• Prevent and treat deep vein thrombosis (DVT) and pulmonary embolism (PE).
• Lower the risk of stroke in individuals with atrial fibrillation, mechanical heart valves, or other heart conditions.
• Manage inherited or acquired clotting disorders, such as antiphospholipid syndrome or protein C and S deficiencies.
• Prevent blood clots after surgeries, especially orthopedic or heart-related procedures.

How Does Warfarin 5mg Work

Warfarin inhibits the liver’s production of vitamin K-dependent clotting factors II, VII, IX, and X, along with proteins C and S. By reducing these factors, it lowers the blood’s ability to clot, preventing the formation of new clots and the growth of existing ones.

How to Use Warfarin 5mg

• Take Warfarin 5mg exactly as prescribed by your healthcare provider, usually once daily.
• Swallow the tablet whole with water, with or without food.
• Follow your doctor’s instructions for regular INR (International Normalized Ratio) blood tests to ensure the correct dosage and prevent complications.
• Maintain a consistent intake of vitamin K in your diet to avoid fluctuations in Warfarin’s effectiveness.
