My husband has had wildly fluctuating INR readings over the past 8 weeks. It is now resting in the doldrums and doesn't show any signs of improvement. He has been AF clear for the past 8 years but for the last few days has had a rapid and irregular heartbeat. We are seeing his GP this pm and I expect he will be transferred to a noac. This will be the second time. He was prescribed Apixaban in April, following an operation under general anaesthetic. He had a bad reaction, i.e. came up in a rash all over his body. he was also having clexane injections and I think the GA plus the Clexane probably precipitated the reaction.
Does anyone have a view as to what the INR level should be before he transfers to a NOAC. I have very little faith in his GP having any awareness.
