Bacterial vaginitis can only be treated with oral metronidazole during menstruation, and external genitalia can be cleaned with a wash, but vaginal suppositories cannot be used during bleeding periods to avoid causing infections. However, the standard treatment for bacterial vaginitis is recommended to better start after the menstruation ends. At that time, you can choose the appropriate external washes and vaginal suppositories for combined treatment, which will be more effective. During the treatment, avoid intercourse, frequently change underwear, maintain genital hygiene, avoid wearing tight clothing, consume fresh vegetables and fruits, exercise more, and enhance resistance.
