I don't give any consideration to what I eat. I eat what I want. If I want a big salad, I eat it. It's been years since I stopped to think "Gee, wonder what this will do to my INR?" Because Gina is right - most of what we eat has little effect.
1 or 2, or 3 or 4 drinks is not going to make someone bleed if they're on Coumadin, unless they already have bleeding ulcers - in which case, they shouldn't be drinking anyway. Over-indulging in alcohol and the bleeding risk has to do with the fact that alcohol is very dehydrating when over consumed and your INR will rise because of it. If it goes above a certain level, then you are at risk for bleeding. As discussed in previous threads, you are basically in no danger with an INR of 5 or below. An INR above that depends on the person. I've been on Coumadin for 16 years and have had zero bleeding incidents. And I've had a few high INR's due to over consumption of alcohol, above 7.0. I try not to over indulge (because I hate the hang-over) but there have been a few occasions in 16 years I was just having way too much fun.
Here's the story of my INR's - some medical people will look at my INR's over the last several weeks and think - WOW she's all over the place, she's hard to stabilize, she needs to watch what she eats. I've been on the same dose for months without a change and I consider myself stable. I'm in or close to my range of 2.5 - 3.5 and the numbers are okay with me. If you were to look at a record of what I ate and drank, you might be able to see why there were some changes - but quite frankly - I don't care.
So here you go - from most recent going backwards:
2.8 3.2 3.8 2.7 3.5 3.5 2.7 2.4 3.6 2.5 3.7
Again, I didn't make one dosage change, didn't think "oops Coumadin" with any bite of food I put in my mouth or any glass of wine, or rum and Diet Coke I had. A warfarin manager may look at those numbers and say "What are you doing - your numbers are all over the place?" My answer would be "I'm in theraputic range, I'm living my life and these numbers are just fine."
