Clindamycin
"I am on day 5of7 of 600mg 3x a day. Little indigestion, very light lower abdomen cramps. The worst side effect for me is a DRY COUGH, however i do have a cold and I am a smoker. Overall great antibiotics for the job.

I had swelling in my cheek that had started to move around my eye before I went to the ER. At first the hospital wasn't sure I had an abscessed tooth because of no pain in the tooth. After 4 visits to the ER for IV sodium hydrochloride i was showing no signs of improvement.

On day 4 the swelling was finally showing in my gum, they took a needle and drained the infection (VERY PAINFUL   NASTY SMELL!). They switched me to clindamycin.

I had my root canal today (600$   filling). Very painless procedure. I can now smile again."
