Bacterial vaginosis is primarily treated with antibiotics that are effective against the overgrowth of specific bacteria responsible for the condition. Metronidazole, an antibiotic that has activity against anaerobic bacteria and some protozoa, is the first-line treatment for bacterial vaginosis. It works by disrupting the DNA synthesis of the bacteria, thereby helping to restore the normal bacterial flora in the vagina.

This treatment approach is backed by clinical guidelines and studies that demonstrate metronidazole's effectiveness in alleviating the symptoms of bacterial vaginosis and restoring the balance of vaginal microbiota. While clindamycin is also an option for treating bacterial vaginosis and can be effective, metronidazole is generally favored due to its strong evidence in studies and favorable side effect profile for this specific condition.

Fluconazole is an antifungal medication used primarily for candidiasis (yeast infections) and does not target the bacterial overgrowth in bacterial vaginosis. Amoxicillin, an antibiotic effective against certain bacteria, is not indicated for bacterial vaginosis due to its limited spectrum against the pathogens involved. Thus, metronidazole stands out as the most appropriate and widely recommended choice for treating bacterial vaginosis.
