Clindamycin
"Did fine for 10 days on this drug for abscessed tooth. Dentist pulled the tooth & then began the most horrible diarrhea! Dr prescribed Flagyll-but I'm still having issues after weeks! I will never take Clindamycin again! I'm using charcoal & oil of oregano, liquid probiotics & got prayed for at church! I've lost ten lbs and have gone from normal stools all my life to a mess!"
