What is a typical recommended dose of warfarin?

Doses of warfarin vary among patients. Most patients take between one and 10 milligrams (mg.) daily. However, doses vary based on each person's clotting time. A blood test called an "INR" (International Normalized Ratio) measures blood clotting speed. Your doctor will determine your dose of warfarin based on your INR and likely check your blood a few days later, and possibly adjust your dose.  A typical INR range for a patient on warfarin is between 1.5-2.5 (but doctors might desire a higher number for some patients).
