Is it safe to associate nattokinase with warfarin, under INR control?

Is it safe to associate nattokinase with warfarin, under INR control?

Probably not safe: Nattokinase has fibrinolytic activity which is a different mechanism than warfarin which is a vitamin k antagonist interfering with synthesis of prothombin and factor vii.

Go see your doctor..: Now! You didn't explain why you're taking Coumadin (warfarin) but we typically aim for inr 2-3 if for blood clot or atrial fibrillation or clotting disorder. We aim for 2.5-3.5 if you have mechanical valve. Inr of 6.1 is way too high. Your Coumadin (warfarin) dose needs to be held/adjusted & inr monitored closely until back into therapeutic range. 8 lb weight loss in 2wks is not normal either. Go see your doctor now! ...Read more
