Clexane 4000IU/ML is an anticoagulant injection used to prevent and treat blood clots, including deep vein thrombosis (DVT) and pulmonary embolism. This low-molecular-weight heparin (LMWH) works by inhibiting specific clotting factors in the blood, reducing the risk of clot formation. It is commonly prescribed for patients undergoing surgery, those with restricted mobility, or individuals with certain medical conditions that increase clot risk. Clexane is administered via subcutaneous injection and is highly effective in both preventive and therapeutic settings.
