Hello all, I've been reading your forum for months and learning so much from all of you, so first thank you for sharing your stories and information.
I joined here because my husband had a bicuspid valve with severe aortic stenosis replaced the last week of February with an On-X mechanical valve. He left the hospital after 5 days, they had to wait until his INR was in range and it was 2.4 the day he left. The Coumadin clinic immediately called him that night and told him to take 1/2 tablet (1.25 mg) of Warfarin and have his blood tested the next day. He did that at the lab and it was 1.8. They told him to retest in 2 days, he did and it was 1.3. That was over this past weekend so calls to them were not answered, he called his surgeon's after hours service and they said to start taking the full 2.5 mg tablets again and re-test on Monday, today. Today's results were 1.0.
He's never had to take meds before in his life, he's 50 years old, active, and in good health other than the valve he had. He was sent home from the hospital with Amiodarone 200mg for 30 days, Aspirin 81 mg, Colchicine for 10 days, Metoprolol 25mg twice a day, Pantoprazole 40mg for 30 days and Warfarin 2.5mg.
Needless to say I'm freaking out about this low INR that has only dropped since his release on 3/1, almost a week ago. It's like he's not taking a darn thing to thin his blood!?! He has calls in now to his surgeon's office, cardiologist and Coumadin Clinic and waiting on their instructions. He hasn't eaten any leafy greens or any Vitamin K foods or drinks that we know of that would affect it.
I guess I'm looking for possible reasons as to why his INR is just dropping. From what I researched, Amiodarone should be making the INR even higher, as well as the aspirin he's taking. Any guesses or things we may not be thinking about? Is there something he can do to up the INR on his own since the people on the phones don't seem too concerned, which is maddening. I know we are new to all this and maybe I'm over-reacting by freaking out, so any advice? Thanks for letting me rant, wish it didn't have to be in my first post here
