My GP rang me yesterday and wondered if I would be interested in going on to Rivaroxaban. I know this is one of the new drugs but I have been on warfarin for 13 years! She said it would avoid having my INR done and I would not have to worry about testing when we went away. But to be honest that doesn’t bother me as I've been testing for so long. I'm not one for change but is Rivaroxaban producing good results?
