I take 10 milligrams every night I think I took another pill by accident so that's 20 mg. What should I do?
Although one OD of warfarin may not be a big deal if it is a single incident in a long time period taking it. I would however be cautious and consume maybe 1/4 cup of bluberries or 1/4 serving of anything that is high in vitamin K. Vitamin K will counter the effect of warfarin. Vitamin K should NOT BE TAKEN WITH WARFARIN. But if you really feel uncomfortable, go to the emergency room. Otherwise call your doctor in the morning.
