    Our TCU does INR's 2X/week unless the patient isn't stable....please note different goals for different diagnoses...and we don't use algorthyms for INR's because of differing absorption levels---I have had patients who needed Vit K, but it took 3 days and 3 doses for their INR to come down, and others who respond in less than 24 hours...each patient and their meds and absorption rates need to be looked at individually...also, my facility gives coumadin at 9p...more important is patient education about what to watch for at home, and how thier diet affects their levels....
