In brief: Maybe

There are some reported cases of patients who take Coumadin (warfarin) and fish oil who then have an elevated inr, the level which is checked when you're on Coumadin (warfarin) to ensure that it's working and your doses are correct.
The interaction is unclear to pharmacologists, so my advice would be to take both and follow your inr carefully. You'd do that regardless of fish oil anyway!
