Frequent blood testing is required to check the level of anticoagulation. Vitamin K is an antidote to warfarin, so the patient must limit intake of vitamin K. Warfarin interacts with most antibiotics. Since warfarin is an anticoagulant, the patient needs to seek medical attention if an injury is sustained due to risk of bleeding. Vitamin D and calcium are unrelated to warfarin.
