Final answer:
Vitamin K is the antidote for Warfarin. It helps in reversing the effects of Warfarin by activating blood clotting proteins.
Step-by-step explanation:
The antidote for Warfarin is Vitamin K. Warfarin is an anticoagulant drug, commonly prescribed to prevent blood clots. However, in cases of an overdose or when there is a need to reverse its effects quickly, Vitamin K is administered because it is essential for activating proteins that clot the blood, counteracting the effects of Warfarin. While menadione is a synthetic analogue of Vitamin K, the naturally occurring forms, such as Kâ and Kâ, are often utilized in clinical settings for reversal.
