Quizplus · Accepted Answer

Phytonadione, also known as vitamin K1, is the antidote for warfarin overdose. It helps restore the body's clotting factors that are inhibited by warfarin. Paroxetine is an antidepressant and would not be used to treat warfarin overdose. Protamine sulfate is an antidote for heparin, not warfarin. Prothrombin factor is not a specific antidote for warfarin overdose.
