surgical prophylaxis
"I had three wisdom teeth (Third Molars) removed on Monday. I took two Clindamycin (150mg) before the surgery without anything in my stomach and was fine. I was instructed to take 4 a day and therefore took one pill every six hours (This is important) One night I fell asleep before taking it and I noticed I had mild heartburn but once I made sure I did not miss a dose this did not return. 
REMEMBER to sit up straight for at least 20 minutes to prevent heartburn, this medication is concentrated and you don't want it laying in your stomach. I was warned about diarrhea, and increased my intake of PLAIN GREEK YOGURT and KEFIR. My poo was mucusy, but no diarrhea. Taking precautions and reading instructions will make this medication effective."
