It has been a great many years, luckily, since I was last on amoxicillin, but long go I would get repeated respiratory infections and be treated with amoxicillin and other antibiotics often. I would always get a yeast infection, invariably. This is a very common response. And other people get diarrhea, but I did not. Antibiotics kill good bacteria, too, be they in the intestines or inside the vagina. And that allows fungus to grow.

Have you been treated with amoxicillin in the past? Did you have side effects?

I would at least eat yogurt while you are on it, as a minimal protective measure.
