Celgene issues letter warning of limited use of heparin drug
Just weeks after the FDA requested revised labeling for the low molecular weight heparin, Innohep, the FDA announced that its maker Celgene Corporation has issued a “Dear Healthcare Professional” letter describing a controlled clinical study that suggests an increased risk of death in elderly patients who received Innohep. Innohep contains tinzaparin sodium that is given to patients in conjunction with warfarin sodium intravenously to treat blood clots that have occurred deep in the veins of hospitalized patients who may or may not have also experienced the occurrence of blood clots in their lungs (pulmonary embolism).
