Clindamycin
"I cut my finger working on my car, It was a very dirty wound that required stitches and I was given Clindamycin in order to prevent infection.  I do not remember any specific warning about the increased chance of any type of intestinal problems associated with this antibiotic.  The Clindamycin caused me to get a C Diff infection that sent me to the ER.  Very painful and passing mucus and blood in the stool.  I have never experienced anything like this before.  I will never take this drug again and suggest doing research before taking this or any other antibiotic.  The problems seem to be clearing up after a course of Flagyl  and Cipro.  More antibiotics to fix the others side effects.  Good luck to anyone suffering from this."
