Metronidazole
bacterial vaginitis
"Right there with everyone else, BV infection. Flagyl 500 twice daily. So happy done with this medicine. I took it for 7 days. I hate this drug!!  Headache,metal taste, cramping and dark urine. I starting feeling better symptom wise on day 5. By day 7 I felt good except for all the side effects. I'm two days off and the burning, itching are back. I'm calling my obgyn today. I'm so afraid she's going to want to put me back on it!!!"
