Clindamycin
"I was perscribed this medication for a tooth infection and upon reading reviews I was TERRIFIED of it. So many negatives! I went ahead and took the advice of those who gave it higher ratings. I am on four 300mg doses everyday, so I take a pill at noon, 6pm, midnight, and 6am. I take it with 20 ounces of water and a small snack or near a meal. Afterwards I make sure to sit up or sleep a little elevated for at least the next 30 minutes. I also am taking a probiotic everyday to counter act against all the "good" bacteria this medication is also killing off. So far I've had ZERO side effects, my tooth pain has gone away and gums no longer swollen. I still have a couple days left but I am assuming it'll be the same."
