jpeters - Sorry - I should have said "for me"... the Eliquis is better.
With warfarin, I had significant problems with keeping the INR stable and a couple times the test results put the lab in panic mode - calling me to sit in a chair, do nothing, rush to an all-night pharmacy to buy the antidote, etc. After a couple of those, I went off the warfarin and monitored the influencing factors for silent inflammation and hyperviscosity and used known natural thinners. Compared to that worry and risk, Eliquis worked better although definitely (for me) still not without side effects.
