I had my C-difficile ten years ago and since then I have not touched any oral broad antibiotics. They actually give you another antibiotic to treat it (vancomycin) . Also one needs the right kind of probiotics.
I keep using the one I received when in the hospital. Fortunately, I did not have a reoccurrence as it can become a real problem - I bleached everything to disinfect! I always tell my doctors to only give me these broad use antibiotics if really necessary. I have not found any research on what happens to people who take antibiotics years after the last occurrence
I am doing CT scan this week so will see what is next.
