I'm so glad to hear he's improving and coming home. Just a word to the wise - my husband was on vancomycin in April in the hospital and about 6 weeks later he came down with c.diff as a result. It is to be avoided at all costs, trust me! We were not told about the risk of that happening. Since then I've learned that probiotics might have helped prevent it. Please ask and/or do your own research. It has taken a terrible toll on his health.Good luck!
