Toxicity of vitamin K can interact with which type of medication?

Explanation:
Vitamin K is needed to activate certain clotting factors. Excess vitamin K counters the action of oral anticoagulants, such as warfarin, which inhibit vitamin K–dependent activation of those factors. So, taking or having high vitamin K levels can reduce anticoagulation and tilt the balance toward clotting, illustrating the direct interaction with oral anticoagulants. The other classes may influence vitamin K status indirectly, but the primary pharmacologic interaction being tested is with oral anticoagulants.
