title: Ask the doctors.  I have atrial fibrillation and have been taking warfarin to prevent blood clots for 10 years.  It has not given me any problems.  However, I do hate going to my doctor's office to get my INR blood test every month.  I'm wondering whether I should switch to one of the newer blood thinners that don't require blood testing.
