I have been on warfarin since 2001. The past couple of months my INR has been spiking for unknown reasons. I was 3.9 on wednesday last week so my gp had me skip wednesday and resume my current dose thursday. By monday my INR spiked to 4.5. THe only thing that has changed is that I have been eating butternut squash which is low in vitamin K. I wonder if it has properties like cranberries that spike the INR?
