Metronidazole
bacterial vaginitis
"I took this twice a day for 7 days, and have never felt so sick on a medication. I had severe headaches, bloating, constant nausea, aches and pains all over. As many others have mentioned, it tastes rancid unless you're really proficient at throwing it into the back of your throat and chugging it down immediately- even in a second, the taste stuck to the back of my throat and made me gag. A couple other really important notes -- this medication lowered both my liver function (hence no alcohol while you're on it! They mean it) AND my platelet count... So I was getting nose bleeds, bruises and some fairly alarming vaginal bleeding while on it as well. "
