Copied from my inr book!
Vitamin K is known to decrease the effects of warfarin, and there are large amounts of vitamin K in such foods as liver, broccoli, brussels sprouts, and green leafy vegetables (e.g., spinach, Swiss chard, coriander, collards and cabbage).
This is where i get my info from! I have been on these pills for 14 years now! As far as i know there has been no changes i go to regular clinic every two weeks and not been told! This is the info that i was given at the start!
I always ask if anything has changed, the one time i decided to eat liver six months ago, i ended up with a two day stay in hospital as my blood went too thick and i nearly died!
as being on this drug for the amount of time i have been and i am on it for the rest of my life!
