@concerned mtn mom When I had c.diff on top of ibs-b and overprescribed antibiotics, my doctor said I could use Imodium; pharmacist said no. We again abit later asked my doctor who again said yes; pharmacist said no. And the answer really is , as your dr said, NO. I ended up not taking anything and had no guidance from dr. it was a rough summer, lost 15 lbs and physically and mentally drained.. and I hear about or read about some who have c.diff and are "over it" reasonably quickly....and am wondering why. Now I have fecal incontinence but at least can take Imodium. Because Ihave so many odd reactins to many meds I was too scared to take anything suggewted.
