What is Coumadin?

Generally, Coumadin refers to warfarin, a commonly used anticoagulant in clinical practice. The detailed analysis is as follows:

Warfarin is primarily indicated for the prevention and treatment of deep vein thrombosis and pulmonary embolism, prevention of thromboembolic events after acute myocardial infarction, and prevention of thromboembolism associated with atrial fibrillation and heart valve diseases. The main adverse effect of warfarin is bleeding. Early signs include bruising, purpura, gum bleeding, nosebleeds, prolonged wound bleeding, and excessive menstrual flow. Bleeding can occur in any part of the body, particularly in the urinary and gastrointestinal tracts. Intestinal wall hematomas may lead to subacute intestinal obstruction, and some patients may develop subdural intracranial hematomas or hematomas at puncture sites. Most patients may experience adverse reactions such as nausea, vomiting, diarrhea, and pruritic rashes, and some may develop allergic reactions or skin necrosis. Warfarin is contraindicated in patients with bleeding disorders such as hemophilia and thrombocytopenic purpura, as well as in those with severe hepatic or renal disease.

Patients are advised to take the medication under the guidance of a physician and should not self-medicate to avoid adverse effects. If any discomfort occurs, medical attention should be sought promptly.
