Getting rid of vaginitis depends entirely on what’s causing it. Vaginitis isn’t a single condition but a group of infections and irritations affecting the vagina, and each type requires a different treatment. The three most common causes are bacterial vaginosis, yeast infections, and trichomoniasis. Treating the wrong one won’t help and can make things worse.
Identifying Which Type You Have
The quickest way to narrow down the cause is to pay attention to your discharge and any odor. Bacterial vaginosis produces a thin, grayish-white discharge with a strong fishy smell that often worsens after sex. It’s not an inflammatory condition, so you typically won’t see redness or swelling. Yeast infections cause a thick, white, curd-like discharge along with intense itching, burning, and sometimes pain during sex or urination. Trichomoniasis, a sexually transmitted infection, produces a yellow-to-green frothy discharge and can cause soreness, but roughly 70% of women with it have no symptoms at all.
Vaginal pH offers another clue. A healthy vagina in reproductive years sits at a pH of 4.0 to 4.5. Yeast infections don’t raise the pH above that range, while bacterial vaginosis pushes it above 4.5, and trichomoniasis can raise it to 5.4 or higher. Over-the-counter pH test strips are available at most pharmacies and can help point you in the right direction, though they can’t give you a definitive diagnosis on their own.
If you’ve never had a vaginal infection before, if your symptoms include fever, chills, or pelvic pain, or if over-the-counter treatment hasn’t worked, a clinical exam and lab testing are worth pursuing. Several sexually transmitted infections mimic the symptoms of common vaginitis, and self-treating can delay the right diagnosis.
Treating a Yeast Infection
Yeast infections are the only type of vaginitis you can reliably treat at home with over-the-counter products. Antifungal creams and suppositories are widely available, and you have options depending on how quickly you want to finish treatment. Miconazole and clotrimazole creams come in 3-day and 7-day regimens. A single-day miconazole suppository (1,200 mg) and a single-application tioconazole ointment are also available for those who prefer a one-and-done approach.
If you’d rather skip the creams, a prescription for a single oral dose of fluconazole (150 mg) clears most uncomplicated yeast infections. It’s a common choice because of the convenience, but it does require a prescription.
Most uncomplicated yeast infections resolve within a few days of starting treatment. If your symptoms persist after completing a full course of over-the-counter antifungals, the infection may involve a resistant strain. Boric acid vaginal suppositories have clinical evidence supporting their use for recurrent or treatment-resistant yeast infections, particularly those caused by less common yeast species that don’t respond to standard antifungals. Vaginal burning occurs in fewer than 10% of users. Boric acid should never be taken orally.
Treating Bacterial Vaginosis
Bacterial vaginosis requires prescription antibiotics. Over-the-counter yeast treatments won’t touch it. The standard treatment is a 7-day course of oral metronidazole, or a vaginal antibiotic cream containing clindamycin if you can’t tolerate metronidazole. Symptoms usually improve within a few days of starting treatment, but finishing the full course matters for reducing the chance of recurrence.
Recurrence is the biggest frustration with bacterial vaginosis. The condition comes back frequently, sometimes within weeks. For women dealing with multiple recurrences, extended suppressive therapy with vaginal metronidazole gel or suppositories twice weekly for three months or more can help keep symptoms at bay, though the benefit tends to fade once the suppressive treatment stops. Newer research has shown that treating male sexual partners simultaneously (with both oral antibiotics and a topical penile cream for 7 days) had a lasting positive effect on vaginal bacterial balance, suggesting reinfection from partners plays a bigger role than previously recognized.
Treating Trichomoniasis
Trichomoniasis is a sexually transmitted infection caused by a parasite, and it requires a specific prescription antibiotic regimen. For women, the recommended treatment is a 7-day course of oral metronidazole. An alternative is a single oral dose of tinidazole.
The critical piece with trichomoniasis that differs from other types of vaginitis: all current sexual partners must be treated at the same time. Without concurrent partner treatment, reinfection is nearly guaranteed. Both partners should avoid sexual contact until treatment is complete and symptoms have fully resolved. Because trichomoniasis increases the risk of other STIs, screening for additional infections is standard practice.
Vaginitis From Hormonal Changes
Not all vaginitis is caused by an infection. After menopause, dropping estrogen levels thin the vaginal lining and reduce natural lubrication, creating a condition called atrophic vaginitis. Symptoms include dryness, burning, irritation, and pain during intercourse. Antibiotics and antifungals won’t help because there’s no infection to treat.
Non-hormonal vaginal moisturizers applied regularly (not just during sex) can relieve mild symptoms by maintaining moisture in the vaginal tissue. For more significant symptoms, low-dose vaginal estrogen cream is the preferred treatment. Applied just twice a week in small amounts, it restores blood flow to the vaginal lining, thickens the tissue, replenishes healthy bacteria, and normalizes vaginal pH. Local vaginal estrogen is preferred over systemic hormone therapy when vaginal dryness and discomfort are the primary complaints, because it delivers estrogen directly where it’s needed with minimal absorption into the rest of the body.
Preventing Recurrence
The vagina maintains its own ecosystem, dominated by beneficial bacteria that keep the environment acidic enough to suppress harmful organisms. Most prevention strategies center on not disrupting that balance.
- Skip the douche. Douching flushes out protective bacteria and allows harmful organisms to take over. Your vagina is self-cleaning.
- Wash gently. Warm water is sufficient for the vulva. Soap is unnecessary on your vulva and should never go inside the vagina.
- Wear cotton underwear. Synthetic fabrics trap moisture, creating conditions that favor yeast growth. Change out of wet swimsuits or workout clothes promptly.
- Use condoms. Condoms prevent the introduction of new organisms and reduce the risk of trichomoniasis and bacterial vaginosis recurrence linked to partner transmission.
- Watch antibiotic use. Antibiotics kill beneficial vaginal bacteria along with the targeted infection. If you’re prone to yeast infections during antibiotic courses, ask about preventive antifungal treatment.
Probiotics containing Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 have the strongest clinical evidence for supporting vaginal health. Randomized trials have shown that taking these strains alongside standard antibiotic treatment for bacterial vaginosis improved cure rates compared to antibiotics alone, and the rebalanced vaginal microbiome remained stable for at least 30 days after stopping the probiotic. Yogurts with live active cultures offer a dietary source of beneficial bacteria, though the evidence is stronger for targeted probiotic supplements than for food sources alone.
