Do you still have to eat yogurt when you take penicillin?
That's what I've always heard about antibiotics, because they kill the good with the bad germs, and the live lactobacillius acidophilus (sp?) that most yogurt has in it, is good LIVE bacteria that helps the "flora" (general chemistry) in your stomach, and it helps out with the loss.
I wasn't told to eat anything with it. Just to take it three times a day.
