In life-threatening warfarin bleeding, what is used next after vitamin K?

• A. Fresh Frozen Plasma or Prothrombin Complex Concentrate
• B. Vitamin K
• C. Cryoprecipitate
• D. Desmopressin

Answer: (B)

Rapid reversal of anticoagulation is what matters in a life-threatening warfarin bleed. Vitamin K helps, but its effect takes hours to days, so you need something that provides immediate clotting factors. The next step is to replace the deficient vitamin K–dependent factors II, VII, IX, and X with a rapid-reversal product. Prothrombin complex concentrate is preferred because it acts within minutes and corrects coagulation quickly. If PCC isn’t available, fresh frozen plasma can be used to supply the same factors, though it comes with larger fluid volume and slower onset. Cryoprecipitate and desmopressin do not reverse warfarin’s effects and aren’t appropriate for this scenario.
