warfarin

a coumarin compound used as an anticoagulant in humans and as a rodenticide, with serious toxicity implications for all species. It is readily absorbed from the intestinal tract and acts to inhibit the reduction of oxidized vitamin K, resulting in a depletion of active vitamin K that is required for carboxylation of coagulation factors VII, IX, X and II.

Accidental poisoning in all species causes massive, spontaneous hemorrhage and death due to anemia. Less severe cases often show pulmonary hemorrhage. In pigs it is the legs that are affected preferentially and in dogs hemorrhage into the anterior mediastinum and lungs is common. Vitamin K is the specific antidote.

A. It is the INR or International Normalized Ratio. It is essential a measurement of how thin your blood is from taking the warfarin. Depending on why you are taking the warfarin the number is usually supposed to be between 2-3.5. I hope this helps.
