CoQ10 is structurally similar to vitamin K and may reduce warfarin effectiveness.
📋 Effect
Reduced anticoagulant effect; decreased INR
💊 Management
Monitor INR if starting/stopping CoQ10. May need warfarin dose adjustment.
Plain Language Summary
This combination can be moderately risky because CoQ10 may reduce the effectiveness of warfarin. Because CoQ10 is similar to vitamin K, it can decrease your INR levels, which may require changes to how your medication is monitored or dosed.
