Answer: Both Warfarin (brand name - and Plavix (generic - clopidogrel bisulfate) are considered blood thinners, but they are very different drugs with different actions. Warfarin works by counteracting Vitamin K in the plasma of the blood. Vitamin K is key in the coagulation pathways responsible for the clotting of blood, and with less activity of Vitamin K blood takes longer to clot. Too little, as well as too much warfarin can be dangerous. If taking a dose that is ineffective, clot formation is not adequately prevented and the problem you are trying to treat or prevent may very well occur. Taking too much warfarin raises the risk of bleeding, especially in the gastrointestinal tract and, in the elderly, the brain. People taking this drug must have their blood monitored to measure the time it takes to clot, which can result in frequent adjustments of their dose. Plasma warfarin concentrations and warfarin effects may be increased. Com, Lasix (furosemide) may displace warfarin from plasma protein binding sites. This interaction is characterized as minor clinical importance. However, everything else being the same, and that she did not confuse her Lasix (furosemide) with Coumadin and take more Coumadin than thought, then this interaction may have contributed to the increased inr. In any case, this is too high and if she is bleeding, or altered mental status or paralysis, she should be sent to the hospital for evaluation and treatment. However if she is stable, hold the Coumadin and retest her inr. She can resume taking her dose when the inr is less than 5.0.
