Over-the-Counter BV Gels vs. Prescription Treatment: What a Head-to-Head Trial Found

Bacterial vaginosis (BV) is the most common cause of vaginal discharge worldwide, often with a thin discharge and fishy odor.¹ Store shelves now offer lactic acid gels that promise to restore vaginal pH and ease odor, without a prescription. A large trial compared one of these gels with a standard antibiotic.

The VITA trial

Researchers in 19 UK clinics enrolled 518 women who had BV symptoms and had had BV before.² They used either:

• Metronidazole tablets (an antibiotic), 400 mg twice a day for 7 days, or
• Lactic acid gel, 5 ml in the vagina once a day for 7 days.²

Results within 2 weeks: symptoms cleared in 70% of the antibiotic group and 47% of the gel group.²

Recurrence: among women whose symptoms cleared and who had 6-month data, about 70% in both groups had BV come back. It took a median of 92 days with the antibiotic and 126 days with the gel.²

Side effects were more common with the antibiotic:²

	Antibiotic	Lactic acid gel
Nausea	32%	8%
Taste changes	18%	1%
Diarrhea	20%	6%

What the CDC recommends

CDC¹ treatment guidelines list metronidazole tablets, metronidazole vaginal gel or clindamycin vaginal cream as first choices.¹ CDC also says studies don’t support vaginal probiotic products as a replacement for or add-on to treatment, and that douching may increase relapse.¹ Some clindamycin vaginal products can weaken latex condoms and diaphragms.¹

Get the diagnosis right first

BV, yeast, trichomoniasis and menopause-related dryness can feel alike. Signs a clinician looks for include vaginal pH above 4.5 and a fishy odor.¹ CDC¹ recommends testing women with BV for HIV and other STIs.¹ Our guides to telling yeast, BV and UTI apart and the limits of home pH tests can help before your visit.

Choosing

1. First episode or unsure what it is? See a clinician for diagnosis and treatment.
2. Want the best chance of clearing symptoms quickly? The prescription antibiotic did better in the trial.²
3. Can’t tolerate antibiotics? Ask whether a gel is reasonable for you, knowing it cleared symptoms less often.²
4. Keep coming back? Recurrence is common after either treatment.²¹ Our article on recurrent BV and partner treatment covers next steps.
