Clindamycin
"I knew the side-effects of this medication and the potential for stomach issues, but I was diagnosed with cellulitis in one of my eyes and did not want to end up with meningitis. The first few days were rough with a lot of heartburn and diarrhea, but as so many other people have mentioned, this can be managed by taking it after or with a meal, eating foods that are not acidic and drinking a lot of water. The good news is that only after 4 hours and the first dose, the swelling started to disappear. It sucks to take it, but it works."
