Clindamycin
"I had a horrible infection affecting my whole left side gum line. The pain was terrible. My Dentist prescribed Amoxicillin and it didn't touch the infection. He then prescribed Clindamycin 300mg every 6 hours. Within a couple of days the pain was so much better but the side effects are a nightmare. I have diarrhea, stomach cramps, bloating & dizziness. I've been watching for C. Diff but I think I just have diarrhea. This medicine is taking care of my infection but I can't wait until it's done so I will feel better. I recommend it."
