Alcohol and INR

[uplbet]

I'd like to learn more about the effect of alcohol drinking on the INR
of somebody who is on Cumadin (or Warfarin).

does the effect consist in raising or lowering the INR?

what is the alcohol effect trend and duration?
I mean: let's suppose one takes his Coumadin pill every day at 6pm,
drinks no alcohol and his INR stays generally in the 2.3 - 2.7 range.
One day he drinks let's say a couple of wine glasses at 8pm: how could
his INR react in the following hours?
Same question if he drinks that wine at noon (only at noon).

Thank you in advance

It's somewhat unpredictable because it is dependent on the alcohol's
effect on liver function.

This will vary from someone with a healthy liver where alcohol can
stimulate liver function, thereby decreasing INR to someone with a "bad"
liver where alcohol can compromise liver function, thereby increasing INR.
