Meta-Analysis: Low-Molecular-Weight Heparin and Bleeding in Patients with Severe Renal Insufficiency

Non-dialysis-dependent patients with a creatinine clearance of 30 mL/min or less who are treated with standard therapeutic doses of enoxaparin have elevated levels of anti-Xa and an increased risk for major bleeding. Empirical dose adjustment of enoxaparin may reduce the risk for bleeding and merits additional evaluation. No conclusions can be made regarding other LMWHs.
