Is it OK for me to drink fruit juice if I take warfarin?

ANSWER

Some experts believe that cranberry and grapefruit juices can affect how Warfarin works. But more evidence is needed to know for sure.

In the meantime, it�s good to be aware. If you drink these juices, you may want to limit yourself to just a glass or two each day.
