bacterial infection
"Dr prescribed this antibiotic for tonsil infection for my 17 year old son. After 2 rounds od 500 mg the infection did not clear... so far no side effects. After this, the doc ordered 10 more days od the same and two days later my son had severe diahrrea with blood in it. He was weak and we stopped immediately. The excess of this. Antibiotic caused an stomach infection that needs to be treated with a different antibiotic. Horrible side effects. I recommend getting another AB if all possible. It did not work for us."
