Louise:
Tell your anticoagulation manager that you can replace blood cells, but not brain cells, if she says something again about reducing your warfarin dosage. Have her think long & hard about that.
If she were the patient, would she mind being a little on the high side as opposed to being a little low, and suffering a stroke as a result?
My husband was on warfarin for 7+ months after his MV repair, due to arrhtythmias from the surgery. His INR range was 1.5-2.0 (set by the surgeon). I struggled with the lab staff at our PCP's office to get it in range; their recommendations on dosage adjustments were too low. Finally they deferred to me, because our PCP is out of the office on Wednesdays, when they do all INR tests. (Thank heavens I have my own INR machine!)
John was up to 8.0mg daily to get an INR of just 2.0.
I take 6.0, sometimes 6.5, to get an INR of about 3.5-4.0. I'm 57, my husband is almost 62. We both eat a lot of veggies. John walks 1-2 miles daily at the college he works at. He drinks lots of fluids; I struggle to, so my INR is usually higher than it should be. Would have been interesting to see how much John would have needed to get up to 3.5!!
I'm glad he's been able to drop taking warfarin. He had an Rx for 5mg and was dipping into my 1's and 2's!!!!
