Food Interactions
Understanding how diet can affect your INR is an important aspect of living a healthy life while on warfarin. Regardless of vitamin K content, all foods have the potential to interact and reduce the effectiveness of warfarin, so it is important to pay close attention to the foods you eat.
More frequent INR testing is recommended to help identify any food/drug interactions with warfarin.1
