The opposite will happen if you do not eat broccoli, and then decides to eat it 3 times a week; the Coumadin level may drop. * Foods rich in vitamin K: Broccoli Brussel sprouts Liver (beef or pork) Chick peas Cucumber peels Greens Cauliflower Spinach Lettuce Green tea * Excessive use or abuse of alcohol is to be avoided as this will lead to major fluctuation in the PT/INR and may lead to excessive bleeding or clot formation. An occasional drink (1-2) may be consumed without problems. Other things that may affect how Coumadin works: * Fever (greater than 101 for 24 hours) * Diarrhea, vomiting * Use of antibiotics Notify your doctor if these occur.
