Ok, we all know warfarin sucks. Patients hate it because it has to be monitored, and if they eat too many collard greens or you prescribe bactrim or cipro they're going to bleed and die. Invariably, we've all had the patient with hematuria and an INR of 10, but totally stable and with a normal hematocrit. You consult "the chart" on uptodate and end up more confused. So, you make something up...um...let's stop taking the warfarin for the next two days, and decrease your dose from 5 mg to 4 mg...and, um...here's 2.5 mg of vitamin K...now, go check in at your coumadin clinic...
