I have been taking this medication for 2 years. Since my surgery, all of a sudden, we are having trouble keeping my INR stable. We keep decreasing the dose but I'm still having issues with my INR shooting high (meaning my blood is too thin). Anyone else having these issues? It's frustrating. I used to only have to check my levels once a month and now it's every week or more often depending on how high it shoots. I feel like a pin cushion! I eat the same things all the time so my Vitamin K does not fluctuate, I haven't lost enough weight to make the dose need to be altered although that wouldn't explain the wild fluctuations anyway.....just curious if anyone else went through this as well. Ok....off to see vampira again! :-)

I am the opposite. My numbers had been steadily dropping so they upped my dosage slightly. I may have had more Vitamin K in what I ate, but I stay really vigilant monitoring it. I can only use Caltrate calium chews as they are the only ones I have found that does not add vitamin K, and I also monitor the bariatric Vitamins I take. Not sure what my issue is, guess I am just weird...LOL

My Doc switched me from Coumadin & lovenox to just xarelto - being on Xarelto i do not have to get blood tests or worry about my diet... its a new Rx - i also dont feel sick like i was on the other two... sorry if thats not more help...
