How Do Antibiotics Cure Bacterial Vaginosis?

Treatment for bacterial vaginosis is antibiotics in the form of ovules inserted into the vagina, pills or creams, states WebMD. Although the infection clears within two to three days, it is important to complete the seven-day treatment regimen.

Bacterial vaginosis is caused by an imbalance in the naturally occurring bacteria in the vagina, explains WebMD. Almost 95 percent of the bacteria is lactobacillus, keeping the pH balanced and controlling the growth of other harmful bacterial growth. When there are low levels of lactobacillus, conditions conducive to bacterial vaginosis exist.

Many that have bacterial vaginosis are asymptomatic, showing no signs of infection. Symptoms that do present during bacterial vaginosis resemble those of sexually transmitted diseases, such as chlamydia, gonorrhea and trichomoniasis, as well as vaginal yeast infection. Itching is not usually a symptom, but a vaginal discharge of a gray or yellow color accompanied by a fishy odor are symptoms, according to WebMD.

Metronidazole, tinidazole and clindamycin are antibiotics prescribed for the treatment of bacterial vaginosis, states WebMD. Avoid having sex and drinking, and continue treatment during menstruation to ensure effective treatment. Prevent bacterial vaginosis by avoiding douching, limiting the number of sex partners, and using condoms while having sex. Practice safer sex by using protection, even with female partners, and washing shared sex toys.
