Warfarin 5mg Tablets

Product Introduction

Warfarin 5mg is an oral anticoagulant used to prevent or treat harmful blood clots, including deep vein thrombosis, pulmonary embolism, stroke prevention in atrial fibrillation, and clot prevention with some heart valves or after certain cardiac events. It blocks vitamin K-dependent clotting factor activation, so dosing must be individualized using INR blood tests. Warfarin has a narrow therapeutic range: too little may not prevent clots, while too much can cause major or fatal bleeding. Diet consistency matters, especially foods high in vitamin K, and many medicines, antibiotics, antifungals, painkillers, herbal products, alcohol changes, illness, and missed doses can shift INR.

How to use

Take Warfarin 5mg at the same time each day and follow INR-based dosing exactly. Do not change diet, alcohol, or medicines without checking interaction risk.

How it works

Warfarin inhibits vitamin K epoxide reductase, reducing activation of clotting factors II, VII, IX, and X and anticoagulant proteins C and S.

Common side effects

Possible effects include bruising, nosebleeds, bleeding gums, nausea, and rash. Serious concerns include major bleeding, tissue necrosis, calciphylaxis, purple toe syndrome, fetal harm, and clotting if INR is too low.
