Will Protamine Reverse Lovenox?

The anticoagulant effect of LOVENOX is inhibited by protamine. This effect may be largely neutralized by slow intravenous injection of protamine sulfate. However, even with higher doses of protamine, the aPTT may remain prolonged to a greater extent than usually seen with unfractionated heparin

unfractionated heparin
Average molecular weight: heparin is about 15 kDa and LMWH is about 4.5 kDa. Less frequent subcutaneous dosing than for heparin for postoperative prophylaxis of venous thromboembolism.

How do you reverse enoxaparin?

Clinical practice guidelines recommend protamine sulfate for reversal of enoxaparin associated bleeds dependent on the time from last administration and dose of enoxaparin.

Can you reverse LMWH with protamine?

Protamine sulphate – the anticoagulant effects of LMWH are not completely reversed by protamine sulphate, but this drug should be considered if patients are suffering significant haemorrhage following recent (<12 hours) administration of a therapeutic dose of LMWH.
