Has anyone experienced coughing bloody sputum? I am 83 years old with permanent AF, taking 10mg Bisoprolol and 5mg Warfarin daily (but 4mg Warfarin on Tuesdays), INR last checked as 2.7. Saw my GP, who checked my chest and back and said to get a chest X-ray, which I should be able to do on Monday (this is Saturday).
I suspect the effect of Warfarin, but wonder if anyone else has had this experience.
Tony.
