Hope you realize that you sound like an idiot to any medical professional. “Monitored closely and have their dosage adjusted….” Newsflash, there’s thousands of medication that need dose adjustments in kidney failure, and warfarin is infinitely more difficult to adjust…in any patient, not just kidney failure. That’s one of the reasons warfarin had higher risks of bleeding, likely too many people were supratherapeutic. Also you mentioned that you can’t use vitamin k; you wouldn’t use just vitamin k if it’s a life threatening bleed since it takes hours to work. You’d use the same reversal agent most use for DOAC’s, which is PCC’s.

I’m not sure if you’ve started this job you’re talking about or not, but you definitely need to do more reading on the subject if you are going to be talking like such an expert.
