Metronidazole
"Turns out I had bacterial vaginitis for a year or so and it was awful. I mean sex was painful, weird smelling discharge, everything was completely out of wack. I finally decided to go to a gynecologist, I told her all of my symptoms and she prescribed me Flagyl 2 a day for an entire week and only BAD side effects I personally experienced were mood swings, diarrhea (every single time) and the horrible chalky taste it left behind.. other than that, cured my BV. Tried every possible cure (natural) and I guess some things just don't work for everyone ... but flagyl worked wonders on me. I recommend .. (consult with your PCP)"
