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. Dalteparin may also be used for purposes not listed in this medication guide.
Fragmin is an injection that contains the active ingredient dalteparin sodium. It is considered to be part of the anticoagulant drug class. Fragmin is used to stop blood clots from forming in the vessels of the blood. Formation of abnormal blood clots can be dangerous, as it can become an embolus.
