What is Coumadin

The drug Coumadin is an anticoagulant and comes in tablet form, with doses of 1 mg, 2 mg and 5 mg. Coumadin is used to treat and prevent blood clots in veins, pulmonary embolism, atrial fibrillation or after heart valve replacement. The main active substance is warfarin, which reduces blood clotting after the first dose within 24 hours; the therapeutic effect occurs 2 to 5 days after the start of treatment.


Coumadin is indicated for the following diseases and conditions:

  • acute venous thrombosis, including recurrences
  • pulmonary embolism
  • ischaemic attacks
  • cerebrovascular accidents
  • prevention of myocardial infarction;
  • Prevention of thromboembolic complications after myocardial infarction;
  • Prevention of thromboembolic complications in patients with atrial fibrillation;
  • in cardiac valvular lesions;
  • Prosthetic heart valves;
  • Prophylaxis of postoperative thrombosis.

Dosage and Administration

The tablets are taken orally with water once daily, preferably at the same time. The INR (coagulation index) is determined before treatment and checked thereafter every 4-8 weeks of treatment.

People taking warfarin for the first time: the initial daily dose is 5 mg for the first 4 days, on the fifth day the maintenance dose depends on the INR and is usually 2.5-7.5 mg per day.

Patients who have previously taken warfarin: initial dose is 5-10 mg daily, followed by 2.5-7.5 mg daily.

Children: initial daily dose of 0.2 mg/kg in case of normal liver function, 0.1 mg/kg in case of impaired liver function. Warfarin should be administered to children by a paediatrician.

There are no specific recommendations for the treatment of elderly patients with warfarin, but they should be followed by a doctor to avoid the risk of side effects.

In patients with liver or kidney disease, INR and body condition should be closely monitored to adjust the dose. People with renal dysfunction should reduce the dose of Coumadin.
