My Grandmother just passed away from a massive stroke. She had recently been taken off Warfarin and I've read that Warfarin should be monitored very closely when you are taking it. But what about when you're taken off of it. She was taken off of it about a month ago and just passed three days ago. A follow-up appointment wasn't scheduled for three months after being off Warfarin to see how she was doing. Was that not good medical advice?
