urinary tract infection
"So. Amoxicillin works fantastic for a UTI BUT I'd never ever take it w/out a probiotic. I get a bottle of acidophilus (maybe a few billion cultures)  at a big box store for under $6.  Reason being is antibiotics kill bacteria both good and bad. My daughter gets thrush and Ive NEVER had a yeast infection until on amoxicillin for over 3 days. These Are side effects of good bacteria being killed off. My dr advised me on this & ive never had any more side effects!"
