Metronidazole
"The side affects from this drug are AWFUL. It makes me feel sick to my stomach, I have constant headaches, a loss of appetite, a metallic taste in my mouth (the medicine itself tastes disgusting and is chalky), makes my pee very dark almost a brown color, and makes me feel very weak and weird. However, despite all of the harsh side affects, this drug does work. This is my 3rd time getting BV and each time this drug has made it go away after 3-4 days. This drug sucks, but I rather deal with the side affects than a smelly/icky vagina."
