Warfarin may be taken with or without food.
Since Warfarin is metabolized by the liver and excreted by the kidneys, dosages need to be lowered in patients with liver and kidney dysfunction.
Frequent blood tests are performed to measure blood clotting time (protime) during Warfarin treatment.
Protime results help doctors adjust medication dose to avoid excessive blood thinning and risk of bleeding.
