New Approaches to Preventing Recurrent Bacterial Vaginosis

Bacterial vaginosis is one of the most common vaginal infections seen in gynecology, and although treatment is usually effective, many women struggle with the same symptoms returning. Recurrence can be frustrating and disruptive, especially when it happens several times a year. New clinical guidance now offers an approach that may significantly reduce recurrence for many patients by treating both the patient and their sexual partner.
At Complete Healthcare, we stay current with emerging evidence to offer the most effective and compassionate care possible. This article explains why bacterial vaginosis comes back, what new research has uncovered, and how this information may guide your treatment plan.
Why BV Keeps Coming Back
Bacterial vaginosis occurs when the normal vaginal bacteria become unbalanced. Although BV is not considered a traditional sexually transmitted infection, research over the past decade has shown that sexual activity plays a strong role in both developing BV and having it recur.
BV is more common among sexually active individuals, and the risk increases with new partners, multiple partners, or a regular partner who carries BV-associated bacteria. Even in monogamous relationships, recurring BV can occur when both partners are not treated. Many women report symptoms improving after antibiotic therapy, only to see them return within weeks or months.
The challenge is not that treatment fails, but that the vaginal environment becomes disrupted again, often due to untreated bacterial exchange between partners.
What’s New in the Updated Guidance
Historically, studies that evaluated treating a male partner showed inconsistent benefits. Earlier research typically relied on oral medication alone and often struggled with poor partner adherence. However, new clinical evidence has shown that treating both oral and topical bacteria in sexual partners is far more effective.
In the most recent trial, women with symptomatic BV were treated with standard oral or vaginal antibiotics. Their male partners received both oral metronidazole and a topical clindamycin cream applied twice daily for seven days. The results were striking. Women whose partners received complete therapy had far fewer recurrences compared with women whose partners were not treated. The lowest recurrence rates occurred when partners completed the full treatment course exactly as prescribed.
Side effects were generally mild. Women sometimes experienced nausea or metallic taste with oral medication, and men had occasional mild skin irritation from the topical therapy. No serious complications were reported.
This new evidence marks a major shift in how clinicians may manage recurrent BV and supports the idea that treating both partners can significantly reduce the cycle of reinfection.
Who Should Consider Partner Therapy?
Partner therapy is most strongly considered for:
Women with recurrent BV, meaning two or more symptomatic episodes
Individuals in a monogamous relationship with a regular male partner
Patients who have tried standard treatment but continue to experience relapse
Partner treatment may also be discussed with:
Women experiencing BV for the first time
Women with same-sex partners
Individuals in non-monogamous relationships where exposure patterns are more complex
Because every patient’s history is unique, partner therapy should be approached through shared decision making.
What the Treatment Involves
If partner therapy is chosen, the regimen typically includes:
For the patient:
Standard treatment with oral or vaginal antibiotics, based on symptoms and preferences
For the partner:
Oral metronidazole for 7 days
Topical clindamycin cream applied to the glans and upper shaft twice daily for 7 days.
Both partners should abstain from sexual intercourse during treatment. If abstinence is not possible, condoms should be used consistently to decrease the chance of reinfection. Adherence to the full regimen is essential for success.
Some insurance plans may not cover partner therapy. If a partner does not have regular access to healthcare, your clinician can help discuss options within legal and medical guidelines.
Why This Matters for Women’s Health
Recurrent BV is more than an inconvenience. It can affect emotional wellbeing, intimate relationships, and physical comfort. Persistent BV can also increase susceptibility to sexually transmitted infections and may complicate certain gynecologic procedures. Breaking the cycle of recurrence can dramatically improve quality of life.
Partner therapy represents an important step forward. Instead of treating the same symptoms over and over, we now have evidence showing that a more comprehensive approach can help restore and maintain a healthier vaginal microbiome.
