Clindamycin
"I took this antibiotic for a tooth infection and it worked over all. The first day I was alright, but into the second day, I started having diarrhea. Now, almost 2 weeks later, I still have diarrhea and it's beginning to bother me because I have to go to the bathroom after I eat any little thing. I recommend any other antibiotic except clindamycin."
