Flagyl
"It seems that the single day/dose medication (4 pills in one day) seems to have less severe side effects than your long treatments (7-10 day). I was diagnosed with BV and I was prescribed Metronidazole (flagyl) with 4 pills. I took two at first because I didn't know how the side effects would effect me but I felt nothing, so I took the other two pills two hours later and still, I feel fine. Maybe a little pain in my abdomen, but if you've ever slept on a bad mattress, the feeling is something of that sort. Not bad. Woke up this morning and my discharge seems to be gone and the itch as well. Now all I'm doing is making sure I don't develope a yeast infection by wearing loose clothing, drinking lots of water/ cranberry juice & eating yogurt."
