bacterial infection
"Took this for gum abscess, tried kefexin and flagyl 10 days before this one and those didn't help much, abscess came back within 2 days. After those my dentist gave me some clindamycin 5 days, it helped perfectly, abscess has not returned and now im waiting my wisdom tooth to be removed in 1,5 weeks.

It has side effects indeed,it gave me bit loose stools, but... i take that over gum abscess anytime. Thank you for making this antibiotic."
