Vaginal plugs for bacterial vaginitis are usually metronidazole vaginal tablets and tinidazole suppositories. Metronidazole vaginal tablets are inserted into the vagina every night at bedtime for 7 days, and tinidazole suppositories are inserted into the vagina every night at bedtime for 7 days. In addition to vaginal plugs, oral medications should be used, most commonly Ornidazole, 0.5g twice a day for one week, with a review of the leukorrhea after 3 days of discontinuation. The patient’s sexual partner should also be treated to avoid cross-infection.
