Contraindications:

Due to an increased risk of bleeding, dalteparin should be used cautiously in patients also receiving oral anticoagulants, platelet inhibitors or thrombolytic drugs. Dalteparin is not recommended for cancer patients undergoing regional anesthesia or for those with allergies to heparin or pork products. Caution should be used in patients with an increased risk of hemorrhage as well as those with a history of heparin-induced platelet depletion. The potential for fetal harm in pregnant women treated with dalteparin has not been studied, therefore the drug should be used only when necessary and nursing mothers should exercise caution as there is some evidence that low levels of the drug can pass into breast milk.
