lillimul-I am sorry your husband has diarrhea from the Rocephin. I never had that as a problem so I can only offer suggestions of what I would do. I would probably wait a day to see if it stops and then if not then get some immodium. Not the maxium but the regular one. If you want I can ask my husband cause he is a pharmacist. The only effect I had was just increased fatigue nothing else while on IV.
I wish I could be of more help..I have been on VSL for a while now so maybe that is why I didn't have that problem. Take care
