Cholestyramine binds toxins A and B of C difficile, but the clinical experience of different investigators has shown marked variation in results. Cholestyramine binds vancomycin and should not be used concurrently with vancomycin therapy. Although not as effective as primary therapy for C difficile, the advantage of anion-binding resins is that they do not alter the colonic flora.
