does vitamin k decrease prothrombin time heparin
What do I need to know about Vitamin K, if I am taking warfarin (Coumadin)? Changes in the amount of vitamin K in the diet can alter the metabolism of warfarin (Coumadin Â®). However, vitamin K does not influence the action of other blood thinners, such as heparin or low molecular weight heparins (Lovenox Â®. Fragmin Â®, or Innohep Â®).
