Although NOACs don't have a chemical antidote, they have a fairly effective antidote in the form of time. You also have to take into account the real world timings involved in these events. The impact of vitamin K treatment is by no means immediate. Warfarin has a long half life and remains in the system much longer than the short half line NOACs (these have to be taken twice daily because of this) and in some studies I saw a while back the the clotting of the blood increased quicker when the NOACs were stopped than in the case of vit K injections being given to warfarin users. This of course depends on the timing of taking these drugs, the time taken to get to A&E etc. I opted for using NOACs because, IMV, it is as safe an option in real world conditions, I can stop and start them easily when need be e.g. elective surgery / dental work, the independence from diet dependency e.g. feasting or otherwise on vit K-rich food, the standard dosage and no blood tests. I've been on them for over a year without any problems.
.... But it all comes down to personal choice/attitude to risk, life style impact if you are offered the choice.
