What can you eat safely if you are on warfarin?

Anything. & Careful! First of all pay attention to the fact that warfarin therapy is life saving in range and life threatening outside that range. Technically you can and should have a varied, healthy diet. That said, you must be cognizant of the fact that dark leafy greens absolutely affect the pt/inr. On the other hand if you eating consistent amounts of greens, your levels should not vary. Check pt-inr regularly.
