Dear Dr. Roach: Many members of my family and I have protein S deficiency and are prescribed warfarin. We are aware of the effects that food, exercise and medicines have in reaction to warfarin. Several of us have INR meters and do our testing at home. I have been on warfarin since 1991, with only a couple of clots, usually when dehydrated.
Proper anticoagulant therapy for protein deficiency
Most people have probably not heard of protein S or protein C, but these are important regulators of the body’s capacity to form a clot
