Warfarin falls in the group of drugs known as anticoagulants. Warfarin has widely been used to treat blood clots such as in deep vein thrombosis-DVT or pulmonary embolus-PE to prevent new clots from forming in the body. Preventing harmful blood clots helps to reduce the risk of a stroke or heart attack.
Warfarin is a drug used in the treatment and prophylaxis of thrombosis and thromboembolism. In other words, Warfarin is used to prevent the formation and integrity of blood clots; clots which, if left untreated, may lead to deep vein thrombosis, pulmonary fibrosis, stroke, or heart attack.
Warfarin belongs to the oral anticoagulant class of drugs, in contrast to injectable anticoagulants such as heparin. Warfarin works as a vitamin K antagonist, vitamin K being responsible for the formation of pro-clotting factors in the blood.
Common side effects of Warfarin include bleeding, bruising, mild stomach pain, nausea, bloating, and taste disturbances. Some patients may experience severe bleeding, depending on the dose.
