Avoid Lovenox for Patient with AKI: Use Heparin Instead

Why AKI matters

Enoxaparin = Low-molecular-weight heparin (LMWH)

• Primarily renally eliminated

• Reduced kidney function → drug accumulation

• Accumulation → excess anticoagulation → bleeding

In acute kidney injury (AKI), renal function can decline rapidly and unpredictably, making dosing less reliable.
