Which vitamin is omitted from parenteral solutions prescribed for patients on warfarin therapy?

Question

Quizplus · Accepted Answer

Vitamin K is omitted from parenteral solutions prescribed for patients on warfarin therapy because warfarin works by inhibiting the enzyme responsible for vitamin K recycling, which is necessary for blood clotting. Therefore, vitamin K supplementation would counteract the anticoagulant effect of warfarin. Vitamins C, D, and E do not affect the anticoagulant properties of warfarin and are not contraindicated in patients receiving this therapy.
