If you are going under any surgery or dental treatment then you may need to stop this medicine for some time but only after consulting with your doctor. Before taking it, you must inform doctor if you are suffering from any kidney or liver disease. Also let your doctor know if you are pregnant or breastfeeding and about all the other medications that you are taking regularly. Warfarin Sodium is an anticoagulant.

Indications
• Deep vein thrombosis • Pulmonary embolism • Stroke prevention
Mechanism of action
Warfarin inhibits synthesis of vit K-dependent coagulation factors VII, IX, X and II and anticoagulant protein C and its cofactor protein S. No effects on established thrombus but further extension of the clot can be prevented. Secondary embolic phenomena are avoided.
