I am planning on going to the local winery tomorrow. I know there is a lot of discussion/disagreement about whether alcohol affects the INR or how (increase or decrease). My question is this--if the wine does affect my INR, how long will it take? I know a change in warfarin takes about 3 days to affect the INR. Would the alcohol effect be immediate or would it take some days? I have done a lot of reading and can't find anything on this subject (how long it would take). I am having my INR checked on Tuesday. Thanks for any input you may have. Mary
