Xarelto
"I was put on Xeralto as an alternative to Warfarin four days before my colonoscopy and endoscopy, stopped one day ahead of the procedures, and resumed 3 days after.  I had already been anemic, probably because of bleeding due to the Warfarin (which is reversable with Vitamin K).  Several polyps were removed, including one large one that had to be partly removed, and later on to
get the other part.  I was now bleeding even worse with the Xeralto.  My hemoglobin fell to 5.2, and I was given several transfusions. Hb rose to 8.7, and I was sent home.  The Xeralto has no way to reverse bleeding, and if it is discontinued, there is an increased chance for a stroke.  I would prefer to have Warfarin and a way to reverse the bleeding."
