Heparin is reversed by protamine, but protamine incompletely reverses factor Xa inhibition of LMWH despite complete neutralization of the antithrombin effect. This results in only about a 60% reversal of LMWH effects.

Does protamine reverse enoxaparin?
For both enoxaparin and dalteparin, protamine does not provide a complete reversal of anti-Xa activity. It is estimated that protamine will reverse up to about 60% to 75% of anti-Xa activity….Enoxaparin (Lovenox®)
| Time Since Enoxaparin Dose | Protamine Dose |
|---|---|
| > 8 hours | 0.5 mg protamine for every 1 mg enoxaparin |
Is vitamin K an antidote for heparin?

A dose of vitamin K is used to reverse the action of warfarin (Coumadin), a blood thinner used routinely for more than half a century and, until recently, the only such option for most people.
What is vitamin K the antidote for?
For reversal of excessive anticoagulation by warfarin, AVK withdrawal, oral or parenteral vitamin K administration, prothrombin complex or fresh frozen plasma may be used, depending on the excess of anticoagulation, the existence and site of active bleeding, patient characteristics and the indication for AVK.
What is antidote for enoxaparin?
Neutralization of enoxaparin by protamine A second infusion of 0.5 mg protamine per 1 mg LOVENOX may be administered if the aPTT measured 2 to 4 hours after the first infusion remains prolonged. Particular care should be taken to avoid overdosage with protamine sulfate.
What is vitamin K antidote?
Vitamin K1 is the only effective antidote for long-term management, but it takes several hours to reverse anticoagulation. Oral vitamin K1 has excellent bioavailability, is rapidly absorbed, and is recommended in the absence of serious or life-threatening hemorrhage.
