Multichris Warfarin Tablets - Warfarin Sodium 5 mg (28 Tablets)

Warfarin is an anticoagulant (blood thinner) medicine used to prevent and treat blood clots. It is taken by mouth and requires regular blood monitoring to ensure safe and effective dosing.

What it is

Warfarin is a medicine that helps prevent blood clots from forming or growing larger. It works by reducing the blood's ability to clot (coagulate).

What it's used for

Warfarin is used to prevent and treat deep vein thrombosis (clots in the veins) and pulmonary embolism (clots in the lungs). It is also used to prevent stroke and other blood clots in people with atrial fibrillation (irregular heartbeat) or those who have had heart valve replacement. It may also lower the risk of another heart attack or stroke after a first heart attack. Warfarin does not dissolve existing clots or reverse tissue damage that has already occurred.

Common side effects

The most common side effect of warfarin is bleeding (haemorrhage), which can range from mild bruising to serious internal bleeding. Other rare but serious side effects include skin and tissue necrosis (death of tissue), calciphylaxis (calcium buildup in small blood vessels), acute kidney injury, and cholesterol microemboli (small cholesterol particles blocking blood vessels). If you notice unusual bleeding, dark stools, blood in urine, or skin changes, seek medical help immediately.

Important cautions

Warfarin is not recommended during pregnancy except in women with mechanical heart valves, because it can harm the unborn baby. Regular INR monitoring is essential to keep the drug working safely and to avoid bleeding or clotting. You must inform any doctor, dentist, or pharmacist that you are taking warfarin, as many other medicines, foods (especially vitamin K-rich foods), and herbal supplements can affect its action. Do not stop or start any other medicine without talking to your healthcare provider.
