What cures bacteria vaginosis (pills wise)?

Metronidazole: The treatment of choice for bacterial vaginosis (an overgrowth of mostly normal vaginal bacteria) is metronidazole (Flagyl® and generics) by mouth for 5-7 days. Tinidazole (Tindamax®), a closely related antibiotic but more expensive, also works. Sometimes clindamycin is used but somewhat less effective. All these oral treatments are much better than most vaginal medicines for BV.
