Yep. Diagnosed with antibiotic induced irritable bowel last week.
Gastro has me taking the probiotic VLS3 and Florastn 3.
I only use the ones tested in double blind studies.
They do ease gut cramping. I'll sure be glad when they change the name for this since it's not a "syndrome" and can be caused by stupid stuff like antibiotics and food poisoning. There is a blood test for it too,but I digress.
It seems it would be beneficial to prescribe (or at least recommend) a course of probiotics alongside a course of antibiotics. I was reading an article on alternative feeding for pets and I believe it mentioned in that how antibiotics can cause problems for the natural gut flora.
