I was put on a strong antibiotic last October for a sinus infection. Well after ONE dose I got really ill. D, pain, and blood. I called my GI and they put me on probiotic. Cleared up the "flare up" I was having because of the antibiotics. So it's something to talk to him further about, but mine said I need to take one every time I'm on an antibiotic. I think he had me taking it at different times of the day though.
