Bacterial vaginosis (BV) requires a prescription antibiotic to treat effectively. There are no FDA-approved over-the-counter antibiotics for BV, so you’ll need to see a healthcare provider, either in person or through a telehealth visit, to get medication. The good news: appointments are usually straightforward, treatment is short, and generic options are affordable.
You Need a Prescription
BV is caused by an overgrowth of certain bacteria in the vagina, and the antibiotics that clear it up are all prescription-only. The most commonly prescribed option is metronidazole, available as an oral tablet or a vaginal gel. Clindamycin, a different antibiotic available as a vaginal cream or oral pill, is the other first-line choice. A provider may also prescribe secnidazole, which comes as a single-dose oral granule you mix into food.
You have several ways to get that prescription:
- Your OB-GYN or primary care doctor. A standard office visit is the most common route. The provider will ask about your symptoms, often do a brief pelvic exam, and may test a sample of vaginal discharge to confirm the diagnosis.
- Urgent care or walk-in clinic. If you can’t get a timely appointment with your regular doctor, most urgent care clinics can diagnose and prescribe for BV on the spot.
- Telehealth services. Many online platforms now offer BV consultations. You’ll typically answer a symptom questionnaire and may describe your discharge. Some services send a prescription to your local pharmacy within hours. This is a convenient option, though an in-person exam gives a more reliable diagnosis.
- Planned Parenthood and community health centers. These clinics offer BV testing and treatment on a sliding-fee scale if cost or insurance is a barrier.
What Treatment Looks Like
CDC guidelines recommend three first-line regimens. Your provider will choose based on your preferences, medical history, and whether you’d rather take a pill or use a vaginal product.
Oral metronidazole is taken twice a day for seven days. It’s the most widely prescribed option. The vaginal gel version is applied once daily for five days and tends to cause fewer digestive side effects like nausea. Clindamycin cream is applied vaginally at bedtime for seven days.
For people who want a faster option, secnidazole is a single dose taken just once. Tinidazole, a close relative of metronidazole, can be taken for as few as two days. Both are considered alternative regimens, meaning they’re effective but typically prescribed when the first-line options aren’t a good fit.
One thing to know about metronidazole: it has a long-standing reputation for causing nausea or vomiting if you drink alcohol while taking it. The actual evidence behind this interaction is weaker and more inconsistent than commonly believed, but most providers still recommend avoiding alcohol during treatment and for at least 24 to 48 hours after your last dose, just to be safe.
How Much It Costs Without Insurance
Generic metronidazole tablets are one of the cheapest antibiotics available. A standard seven-day course (14 tablets of 500 mg) costs roughly $16 to $17 at most pharmacies without insurance. With a discount coupon from services like GoodRx, that can drop below $10.
The vaginal gel form is significantly more expensive, averaging around $87 for one package at full price. Clindamycin cream falls in a similar range. If cost is a concern, oral metronidazole tablets are by far the most budget-friendly choice, and they work just as well.
Why Over-the-Counter Products Won’t Clear BV
You’ll find boric acid suppositories, probiotic supplements, and vaginal pH products marketed for BV relief at most drugstores. None of these are proven replacements for antibiotics.
Boric acid suppositories have limited data supporting their use as part of a multi-step approach for women with repeated BV infections. In that context, boric acid is used after a full course of antibiotics and followed by months of suppressive gel therapy. It’s not a standalone treatment, and it’s not a substitute for getting a prescription.
Probiotics containing vaginal lactobacillus strains (such as L. rhamnosus GR-1 and L. fermentum RC-14) have shown some ability to restore healthy vaginal bacteria in small studies. One study found that oral intake of these specific strains increased vaginal lactobacilli over a 60-day period. However, the CDC’s review of the overall evidence concluded that no probiotic products are supported as a replacement or add-on therapy for BV. They may help maintain vaginal health generally, but they won’t resolve an active infection.
If BV Keeps Coming Back
Recurrence is one of the most frustrating aspects of BV. About half of women treated for BV experience another episode within 12 months. If that’s your situation, your provider may recommend a longer, multi-phase approach.
A common strategy for recurrent BV starts with a full seven-day course of oral antibiotics, followed by 21 days of intravaginal boric acid, then four to six months of twice-weekly metronidazole gel to suppress the overgrowth long term. This regimen requires close follow-up and a provider willing to manage chronic BV, so if your current provider isn’t offering solutions beyond “here’s another round of antibiotics,” it may be worth seeking out a specialist or a clinic that focuses on vaginal health.
BV During Pregnancy
BV during pregnancy is treated with the same antibiotics used outside of pregnancy. Oral metronidazole and clindamycin are both considered safe and are the standard choices. If you’re pregnant and notice the telltale thin, grayish discharge with a fishy odor, getting treated promptly matters because untreated BV has been linked to preterm delivery and other complications. Your prenatal provider can prescribe treatment at a routine visit.
