“Vaginal probiotics treat an active case of bacterial vaginosis.”
Some small studies report benefits, but products, routes and outcomes differ, and study quality is uneven. Prevention after antibiotics is a different question from treating an active infection. Current evidence does not establish a dependable treatment effect for vaginal probiotics as a general category.
Vaginal probiotics are being studied for BV, but the evidence is not strong enough to rely on a generic product to treat an active infection. Results from oral products or recurrence prevention after antibiotics cannot establish that claim.
Safety note: Do not replace prescribed BV treatment with a probiotic. Get symptoms assessed, especially during pregnancy, because different causes of vaginal symptoms need different treatments.
Talk to a healthcare professional if: Seek assessment for new, persistent or returning vaginal symptoms. Tell the clinician if you are pregnant.
Some research is promising, but choosing a probiotic by its label is not a reliable way to treat active BV. Standard treatment remains the appropriate starting point.
Get a diagnosis and discuss recommended treatment before adding a probiotic.
