Detailed Answer:
Hi and thank you for asking!
I read your query and understood your concerns.

You don't need to monitor I.N.R levels. I.N.R is monitored when you use warfarine, since the Apixaban has a different mechanism of action you don't need to measure I.N.R.

Hope this will be of help!
Wish you health!
