Note that protamine will reverse enoxaparin only by ~50%. May consider re-dosing at 0.5 mg protamine per mg enoxaparin if bleeding persists (max 25 mg). Reversal of enoxaparin: Follow Xa level after giving protamine and then q2hr.

Unlike unfractionated heparin (UFH), the low-molecular-weight heparin enoxaparin (Lovenox) is excreted mainly by the kidneys. It is estimated that protamine will reverse up to about 60% to 75% of anti-Xa activity….Enoxaparin (Lovenox®) Time Since Enoxaparin Dose Can you reverse enoxaparin?įor both enoxaparin and dalteparin, protamine does not provide a complete reversal of anti-Xa activity. If the LMW heparin dose has been given within 3-4 hours give 1 mg protamine/1 mg of enoxaparin dose.
