No special dietary requirements or restrictions exist. Diet should be as tolerated.

An exception, however, applies to patients on oral warfarin therapy, who must avoid vitamin supplements that contain vitamin K and must limit foods that are high in vitamin K (eg, broccoli, cabbage, red and green lettuce, onion, peppers, spinach, oils, mayonnaise, black and green leaf teas). For the patient on oral warfarin therapy, the diet should remain steady, with no drastic changes in content, in order to facilitate accurate, regular monitoring of the INR. Drastic changes in vitamin K–containing foods or supplements can affect the INR.
