[|Human|] My dad had his coumadin level checked by his home health nurse today it was at 7.1 so she told him not to take it for the next 3 days but his nose has been bleeding all day. He is on constant oxygen and wears a cpap at night...how dangerous is this?
[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should immediately consult emergency department and get done1. Nose packing to stop the bleeding2. Vitamin K injection3. Injection of other hemostatic agents like (ethamsylate and tranexaemic acid). Your fathers' Coumadin level is very high. So the reason for nose bleeding is high Coumadin level. It is anticoagulant in nature. It is vitamin K antagonist. So to reverse its action vitamin K should be given parenterally (injection) to stop the Coumadin effect and also the bleeding. He may need nose packing and other hemostatic agents too. So better to take him to emergency room and discuss all these and start appropriate treatment.
