By preventing the blood clots that trigger heart attack and stroke, the anticoagulant drug warfarin (CoumadinÂ®) saves countless lives. Doctors must regularly monitor patientsâ blood levels in order to prescribe a high enough dose of warfarin to prevent deadly blood clots, but not an excessive dose that could lead to fatal hemorrhage.
In the early 1950s, warfarin was found to be effective and relatively safe for preventing thrombosis and thromboembolism in many disorders. It was approved for use as a medication in 1954, and has remained popular ever since. Warfarin is the most widely prescribed oral anticoagulant drug in North America.he major side effect of warfarin use is bleeding. Risk of bleeding is increased if the INR is out of range (due to accidental or deliberate overdose or due to interactions). Many drug interactions can increase the effect of warfarin, also causing an overdose.
