I'm on 6mg warfarin for prosthetic composite aortic valve graft. my inr used to be between 2.5-3.5 but today it is 3.7. what foods increase inr?

See below: There are many foods that affect the inr but there are many more medicines that affect it as well. For a list of common foods that increase inr (by no means all-inclusive), see the following link: http://www.Pamf.Org/anticoag/patients/handouts/warfarin_and_diet.Pdf.

INRs will fluctuate: That's why we have to check it so often. Foods containing vit k like leafy vegetables will resistant warfarin and lower the inr. Antibiotics decrease vitamin k production by our own healthy gut bacteria, and tend to raise the inr temporarily.
