Warfarin (Coumadin) diet

Warfarin (brand name Coumadin) is a blood thinner.

Blood thinners are prescribed for people who have had blood clots or are at high risk for them. Warfarin works by blocking vitamin K’s ability to help our blood to clot.

Foods can interfere with warfarin in a few ways:
1. They can be high in vitamin K and overwhelm the warfarin effect.
2. They can change how our body clears warfarin.
3. They can affect warfarin in other ways.

Experts usually recommend keeping a consistent diet. This helps keep warfarin’s blood thinning effect predictable.
