Are there any prescription treatments for bacterial vaginosis (BV)?

Bacterial vaginosis (BV) is an infection of the vagina. It's caused by an overgrowth of certain bacteria. The vagina normally contains a variety of bacteria, but BV occurs when the balance is upset. Symptoms of BV include vaginal burning, discharge, and a "fishy" odor.

Doctors treat bacterial vaginosis with prescription antibiotics. Metronidazole (brand name Flagyl or Metrogel) and clindamycin (>Cleocin) are the most effective treatments. They're both available as pills, vaginal creams, or gels. Therapy lasts from one to seven days, depending on which medicine you're using, and studies show that these treatments cure the infection 90 percent or more of the time. It generally isn't necessary to treat male sexual partners of infected women.

It is important to seek treatment to avoid further complications such as PID (Pelvic Inflammatory Disease), other STDs (Sexually Transmitted Diseases), and pregnancy complications if you are currently pregnant.
