It is commonly used to treat blood clots such as deep vein thrombosis and pulmonary embolism and to prevent stroke in people who have atrial fibrillation, valvular heart disease or artificial heart valves. Less commonly it is used following ST segment elevation myocardial infarction STEMI and orthopedic surgery. It is generally taken by mouth but may also be used by injection into a vein. The common side effect is bleeding. Less common side effects may include areas of tissue damage and purple toes syndrome. Use is not generally recommended during pregnancy. It is recommended that the effects of warfarin typically be monitored by checking prothrombin time INR every one to four weeks. Many other medications and dietary factors can interact with warfarin, either increasing or decreasing its effectiveness. The effects of warfarin may be reversed with phytonadione vitamin K1, fresh frozen plasma, or prothrombin complex concentrate. Warfarin decreases blood clotting by blocking an enzyme called vitamin K epoxide reductase that reactivates vitamin K1. Without sufficient active vitamin K1, clotting factors II, VII, IX, and X have decreased clotting ability. The anticlotting protein C and protein S are also inhibited but to a lesser degree. A few days are required for full effect to occur and these effects can last for up to five days. Warfarin first came into commercial use in 1. In 1. 95. 4 it was approved for medical use in the United States. It is on the World Health Organizations List of Essential Medicines, the most effective and safe medicines needed in a health system. Warfarin is available as a generic medication. The wholesale cost in the developing world is about US1. In the United States it usually costs less than 2. Medical useseditWarfarin is used to decrease the tendency for thrombosis or as secondary prophylaxis prevention of further episodes in those individuals who have already formed a blood clot thrombus. Warfarin treatment can help prevent formation of future blood clots and help reduce the risk of embolism migration of a thrombus to a spot where it blocks blood supply to a vital organ. Warfarin is best suited for anticoagulation clot formation inhibition in areas of slowly running blood such as in veins and the pooled blood behind artificial and natural valves and in blood pooled in dysfunctional cardiac atria. Thus, common clinical indications for warfarin use are atrial fibrillation, the presence of artificial heart valves, deep venous thrombosis, and pulmonary embolism where the embolized clots first form in veins. Warfarin is also used in antiphospholipid syndrome. It has been used occasionally after heart attacks myocardial infarctions, but is far less effective at preventing new thromboses in coronary arteries. Prevention of clotting in arteries is usually undertaken with antiplatelet drugs, which act by a different mechanism from warfarin which normally has no effect on platelet function. Alternative anticoagulantseditThis section needs to be updated. Please update this article to reflect recent events or newly available information. October 2. In some countries, other coumarins are used instead of warfarin, such as acenocoumarol and phenprocoumon. These have a shorter acenocoumarol or longer phenprocoumon half life, and are not completely interchangeable with warfarin. Several types of anticoagulant drugs offering the efficacy of warfarin without a need for monitoring, such as dabigatran, apixaban, edoxaban and rivaroxaban, have been approved in a number of countries for classical warfarin uses like the more common types of atrial fibrillation, and others in the same drug classes are under development. There is a reversal agent available for dabigatran idarucizumab1. Dosing of warfarin is complicated because it is known to interact with many commonly used medications and certain foods. These interactions may enhance or reduce warfarins anticoagulation effect. To optimize the therapeutic effect without risking dangerous side effects such as bleeding, close monitoring of the degree of anticoagulation is required by a blood test measuring an INR. During the initial stage of treatment, INR is checked daily intervals between tests can be lengthened if the patient manages stable therapeutic INR levels on an unchanged warfarin dose. Newer point of care testing is available and has increased the ease of INR testing in the outpatient setting. Instead of a blood draw, the point of care test involves a simple finger prick. When initiating warfarin therapy warfarinization, the doctor will decide how strong the anticoagulant therapy needs to be. The target INR level varies from case to case depending on the clinical indicators, but tends to be 23 in most conditions. In particular, target INR may be 2. In addition, for the first three days of warfarinization, the levels of protein C and protein S anticoagulation factors drop faster than procoagulation proteins such as factor II, VII, IX, and X. Therefore, bridging anticoagulant therapies usually heparin are often used to reverse this temporary hypercoagulable state. Maintenance doseedit. Vitamin K1 warfarin interaction effect. When warfarin levels are high, people have more risk of bleeding. Conversely, lower levels of warfarin lead to increased risk of blood clots. There is a narrow range where the benefits of warfarin are greater than the risks, its therapeutic window. Certain drugs, herbal medicines and foods can interact with warfarin, increasing or decreasing a previously stable warfarin level. Recommendations by many national bodies, including the American College of Chest Physicians,2. The maintenance dose of warfarin can fluctuate significantly depending on the amount of vitamin K1 in the diet. Keeping vitamin K1 intake at a stable level can prevent these fluctuations. Leafy green vegetables tend to contain higher amounts of vitamin K1. Green parts of members of the family Apiaceae, such as parsley, cilantro, and dill, are extremely rich sources of vitamin K cruciferous vegetables such as cabbage and broccoli, as well as the darker varieties of lettuces and other leafy greens, are also relatively high in vitamin K1.
