I would like to ask all of you on any of the Noac's (especially Apixaban) if it was explained to you by EP or GP how we know they are working for SURE. I know the stock answer is that they work in a different way to Warfarin and without any food or drug interactions will not vary as warfarin does. BUT knowing what my INR is does give me some confidence in warfarin, it just seems we have to just assume the Noac's are working as there is no test to confirm. Just about every other drug we take a blood test tells us if it is working and whether any adjustments need to be made as we are all different and react differently.
I am probably having to change from warfarin due to side effects, but need convincing the noac's do indeed work and also how a lower dose can work as well as the higher one. A difficult question I know but any thoughts you can give me would be really helpful. Many thanks Joyce.
