Clindamycin
"I took Clindamycin because of a severely painful infection that was present both before and after a root canal. I was apprehensive about taking this drug do to all of the bad reviews, however, the only side effect I experienced was the metallic taste, which honestly wasn't so bad. After what felt like childbirth pain near my root canal for two weeks that wasn't responding to other antibiotics, the pain subsided after just three days of taking this medication. If I had to take it again, I would do it in a heart beat. I took precautions when taking this medication, which is why I believe I didn't have any of the nasty side effects. While taking Clindamycin, I ate a bready substance both before and after taking each pill along water."
