It's brown to reddish brown. I've had it happen twice.So I never asked about in my urine
Once in the early 1970s after several days of heavy drinking. A shot of vit K cleared it within a day or two.
The second time was on vacation in Spain in the early 1980s which, I think, was due to drinking and diet changes. I was too scared to go to a Spanish hospital for a vit K shot (I don't speak Spanish) so I stopped all drinking and watched my diet.....and drank a lot of water for the remainder of our trip. When we got back home my PT (the anti-coagulation test before INR) was within my PT range.
Those are the only two times over all of the years I have been on warfarin when I have had blood in urine. Both of these events were during the "dark ages" of warfarin management. Now, with the INR system and "home testing"........and a much better professional, and patient, understanding of ACT most of the old issues with warfarin are no more.
