Dalteparin is an anticoagulant that helps prevent the formation of blood clots.
Dalteparin is used together with aspirin to prevent blood vessel complications in people with certain types of angina (chest pain) or heart attack.
Dalteparin is also used to prevent a type of blood clot called deep vein thrombosis (DVT), which can lead to blood clots in the lungs (pulmonary embolism). A DVT can occur after certain types of surgery, or in people who are bed-ridden due to a prolonged illness.
Dalteparin is also used long-term to treat a type of blood clot called venous thromboembolism (VTE) in people with cancer.
