This is the first time I have written in to this board- I have been a reader for a long time and the information here is so helpful. It is comforting to know that so many people share this awful condition- at least we aren't alone. Does anyone take Levbid and find that it does not help with IBS d? I am on it twice daily for 12 days and find that my symptoms have not changed- daily attacks of IBS d are continuing. Am recovering from diverticulitis and was on Flagyl(developed an allergy to that one ), Cipro and Clindamycin for two weeks. All stool culture tests for c diff, ova and parasites and other cultures were negative. The GI doc has me on a low residue/low fiber diet for 2-3 months. I do take Primadopholis every day to help get the good bacteria back in balance. I was wondering if it is ok to take immodium along w/ the Levbid. I also stopped my calcium (Caltrate 600) and wonder if it would be ok to resume taking it. Anyone have any related problems or suggestions? I'd appreciate them- the Dr. is so busy and not available most of the time to follow thru with these concerns. Thanks for listening.
