I get bacterial vaginal infection quite often..what would u recommend to prevent it from occurring so often?

Bacterial vaginosis: Despite the effective treatments for bacterial vaginosis, recurrence of symptoms within three to six months is common. If your symptoms recur soon after treatment, make an appointment with your doctor to discuss treatment options, one of which is extended-use Metronidazole therapy. Eating certain types of yogurt or other foods containing lactobacilli can be helpful for some.

Dr Ein agreed

See below: I assume you are referring to bacterial vaginosis (previously bacterial vaginitis). After treatment with metronidazole, Clindamycin or tinidazole, you could try oral and/or vaginal administration of lactobacillus containing probiotic preparations which have had variable sucess. Consider having your sexual partner treated with Metronidazole or Clindamycin although this is of unproven benefit.
