Vitamin K

My INR levels continue to fluctuate. The lack of stability is inherent to the use of Warfarin as a blood thinner. The fact of my chemotherapy just complicates matters. Warfarin interacts with other drugs and any changes of medication can affect the effectiveness of the Warfarin.

Diet also plays a part. Vitamin K is present in many foods and is a blood clotting agent i.e. It helps the blood to clot. In my case I need to moderate the amount of Vitamin K I eat to avoid counteracting the Warfarin. I need to be a bit stricter in my intake of certain foods.
