Does alcohol reduce effectiveness of warfarin ?
Posted , 4 users are following.
My best pal recently had open heart surgery resulting in a replacement valve & work to correct a leaky valve.
As a result going forward he will be taking warfarin for the rest of his life.
As things stand a couple of months after the operation his walfrin readings are very varied & keep going up & down.
He has always enjoyed 3+ large glasses of wine each day and has continued a similar pattern post operation.
Clearly this intake is way above the recommended 1.5 units for those taking walfrin.
Notwithstanding the obvious impact of such daily volumes for anybody never mind someone having had heart surgery, I do have two specific questions:
1) Could the alcohol be one of the reasons for the lack of stabilisation on his walfrin readings ?
2) Could the alcohol actually have a negative impact on the effectiveness of the Walfrin ie causing increased risk of heart attacks ?
I love my mate to death but am concerned that he may be in denial as to the impact of his continued drinking.
Any advice would be greatly appreciated.

Your not supposed to have alcohol while taking warfarin full stop as alcohol thins your blood.
Dont get me wrong, i'm not saying i have never had alcohol, i have a glass of wine every now and then (like once every few months) and it definatly effects my inr reading, it can make it unsettled for about 2 weeks. Luckily i home test so i can keep an eye on it .

The usual advice:
While alcohol can be a source of pleasure and enjoyment, drinking too much or at the wrong time, can cause problems when on warfarin. Alcohol has a marked affect on the action of warfarin.
The important thing is to know where the benefits end and the risks begin!
We recommend that you should drink the same amount of alcohol each day, thus avoiding big variations in the amount you drink from day to day. The guide to the amount of alcohol that is both safe to drink and good for your general health, is no more than 21 units of alcohol for a man or 15 units for a woman a week.
1 unit of alcohol equals:Half pint of ordinary strength pub beer, lager or cider
Small glass of wine
Single measure of spiritPlease remember that some drinks are stronger than others. The strength of alcoholic drinks is shown on the labels.

Is he also overweight, he may have a fatty liver, and that also impairs liver function.
I notice with my husband if I feed him too much dark green food for the week it also affects his levels, so i try to keep it well mixed up with other vegetables, carrots, sweet pototoes, parsnip, beans, pumpkin, and keep the swiss chard, and cabbage, broccoli and other very dark green veges towards a smaller serving even though they are reccommended to us by the dietitian.

I have to do mine once or twice a week - hence why i bought my own machine to home test!
The longest i have ever gone without testing is about 2 weeks because my levels have been very good for months.

We got a machine when i was about 8 i think. Ive always had to have a test every week (unless the reading is too high or low then its more) so i was missing at least one day at school per week to go to the hospital. My attendence was already poor from having so many surgeries and illnesses and general appointments and we just found it easier because it would mean i could test it then go to school rather than have a day off.
The machine has been replaced by a newer version about 6 years ago and i bought it because i couldnt imagine having to go to the hospital more than i already do! It also means when im feeling poorly (or if i have had alcohol one evening) i can just test it when i want.
Once per year i have to take the machine to the hospital and they test my blood on my machine and theirs to make sure the readings are correct and give it a general MOT. Best thing i ever got!

You said you take Warfarin, what do you take it for? Have you had many surgeries?

I was born with Shones Complex. I had my first surgery at 3 days old. I had 4/5 holes in my heart and repairs to my mitral and aortic valves, and evenutally had them both replaced with mechanical valves. They had the be replaced periodically as my body grew (and obviously they didnt) i also have a leaking aortic valve.
I have had 12 surgeries so far. I am awaiting my 13th to either replace both valves again or have a heart transplant. At the moment its looking like they are going to replace the valves again because i am not eligable for the transplant list (even though they say a transplant would be less risky now)

My problem is that because i have had so many surgeries now, my heart has alot of scar tissue. They explained it to me as, they would usually go in and pump a balloon inside the heart to stretch it so that they have room to work and do what they need too, then when they are finished they deflate the balloon so the heart goes back to normal size. However because i have so much scar tissue the balloon wont pump very much because scar tissue doesnt stretch as well, leaving them with not alot of room to work. So effectivly they would be forcing my valves in.
But if it is successful they believe it should be my last valve replacement as my body has stopped growing now - which would be amazing!
I am back at the hospital next week so hopefully i will know more.

It makes sense about the scar tissue and good they explained in such detail as we need to know these things! such good news that this valve op wouldn't need to be repeated as before because you've now finished growing - these surgeons are just wonderful, I went to Harefield Hospital for my operation which only does heart and lung ops, bit of a distance for my hubby and two kids to visit but they were very good - there were people all ages, (oldest was 95) having valve replacements and I was told its just routine for the surgeons!!!!! Let me know how you get on next week, will keep fingers crossed you can get things sorted soon. Thinking of you.

One patient I met was a retired dancer and had gone through her career with a faulty aortic valve from birth until going to our GP with a cough.

In an ideal world i would just like my valves re replaced again. If they can successfully do that then they say it should be my last time they will be replaced.
A heart transplant doent nessercerily mean thats your last surgery, some people have to have 2nd heart transplants at a later date.
I am not keen on a transplant because of he drugs afterwards and the risk of cancer they give you (cancer is a very common in my family already) but they say a transplant would be less of a risk for me.
At the end of the day, its the surgeons who know best and they are the ones who have to do the work, i just go to sleep and try and keep breathing, they do the hardwork so whatever they suggest is best i will go with. I am going back to hospital next wednesday so i will see what they say then

Strange today my INR had dropped from 2.7 to 1.9
When first told that I had aortic stenosis a very old memory from 1952 popped into my head. I was having an Army Medical (National Service then) and the doctor who was listening to my chest suddenly looked up and asked if I'd had rheumatic fever as a child. I said No and he grunted and shook his head and again listened intently but did not say anything more. I believe that some people used to eat soap before their medical as it was supposed to affect their heart rhythm.
They sent me to hospital for a check up but not for my heart but for my eyes. I think that they thought I was malingering when I said that I could not read any letters on the chart without my glasses.

I have some sharp bits of wire near the surface that are painful if touched and quite a few bony spurs along the join.

When I was in having my valve replaced a day patient was in to have his wire removed but he was the hospital admissions manager so had an advantage.
I once dropped a pill bottle on the train with a cop sitting opposite me.
He picked them up and studied it before handing it back.
Two bits of my wire are quite near the surface and as with the knobbly bits I feel them when showering and often when buttoning up my shirt. My wife says what's the matter when I yelp if she rests her arm on my chest when in bed.

Do they send you a report on it? The lovely informative lady who does mine does a running commentary for me during it. She said that she would send me a copy of her report but it did not arrive.
She is really good. Prior to her I had a giant of a Guy who never spoke and pinned me to the table like a wrestler trying for a submission.
An interesting girl I had was an Ex Olympic runner.

My local hospital cardiology gave me an appoinment as well as the hospital in Brighton where I had my surgery along with an appointment to see the surgeon.
Each said they wanted to do their own and their computer systems are separate. Brighton did the scan at the Royal Sussex but the surgeon was not seeing patients there but at Hove Poly Clinic. Guess what ? People at Hove were having echocardiograms done there. They love to make you travel.
