📖
What is the Warfarin Dosing Calculator & How does it work?
Warfarin is an anticoagulant medication commonly prescribed to prevent blood clots in patients with certain heart conditions, atrial fibrillation, and venous thromboembolism. The dosing of warfarin requires careful consideration of several factors including the patient’s weight, age, sex, and other medications they may be taking.
Dose = frac{Target INR}{INR Ratio} times Weight (kg)
Dose = Warfarin dose in mg per day
Target INR = Desired International Normalized Ratio
INR Ratio = Ratio of actual to target INR
Weight (kg) = Patient’s weight in kilograms
The warfarin dosing calculator helps healthcare professionals determine the appropriate dose based on these factors, ensuring effective anticoagulation while minimizing the risk of bleeding.
