Warfarin 4mg

Warfarin 4mg — Uses and Benefits

Warfarin is used to prevent and treat conditions caused by unwanted blood clots forming in the veins, arteries, heart, or lungs.

WHAT THIS MEDICINE IS USED FOR

• Preventing and treating deep vein thrombosis (DVT)
• Preventing and treating pulmonary embolism (clots in the lungs)
• Preventing stroke in people with irregular heart rhythm (atrial fibrillation)
• Preventing clots in people with artificial heart valves
• Preventing clots after certain heart attacks

HOW IT WORKS

• Blocks vitamin K-dependent clotting factors made by the liver
• Slows down the blood's ability to form clots
• Helps keep blood flowing smoothly through veins and arteries
• Takes several days to reach full effect, so doses are adjusted gradually

WHAT IT IS NOT USED FOR

• Not used for immediate pain relief
• Not a treatment for infections
• Not used to dissolve an existing large clot quickly (other medicines are used for that)
• Not for use without regular blood monitoring

Your doctor will decide the right dose based on your blood test results (INR) and condition.
