I am taking Xarelto and have been for over a year for afib. Today after doing my normal 1.5 to 2 mile walk, I went to the bathroom and saw fresh blood. At first I thought I might be getting a bladder infection, but have since discovered is it rectal blood. That occurred about 5 p.m., four hours ago. Question is, should I take today s pill or not. Afib happens occasionally, 1 to 3 times per month, not constantly.
