 Venous thromboembolism VTE is a significant cause of morbidity and mortality in hospitalized patients. It is a well-known complication in patients after major surgery or trauma. More recently, medically ill patients have been identified as another high risk group with up to 15 of patients experiencing VTE in the absence of prophylaxis. 1 Several studies have found the use of enoxaparin, dalteparin, and fondaparinux to be safe and effective in reducing risk of VTE by 45 to 63 in medically ill patients. 1-3 Additionally, enoxaparin has been found to be at least as safe and effective as unfractionated heparin for VTE prophylaxis. 4 Enoxaparin 40 mg once daily has been shown to be a safe and effective prophylactic therapy in hospitalized patients. 1
