What Is the Best Treatment for a Yeast Infection?

The best treatment for most yeast infections is an over-the-counter antifungal cream or suppository, or a single dose of a prescription oral pill. Both approaches clear the infection at nearly identical rates, with about 75% of patients remaining cured five weeks after treatment. Your choice comes down to preference, convenience, and whether your infection is straightforward or complicated.

Over-the-Counter Antifungals

Three antifungal ingredients dominate pharmacy shelves: miconazole, clotrimazole, and tioconazole. They all work the same way, disrupting a key component of the yeast cell’s outer membrane so the cell breaks apart and dies. The difference between products is mostly about how long you use them.

Miconazole (the active ingredient in Monistat) comes in three formats. A single-dose suppository delivers the full treatment in one application. A three-day suppository is inserted at bedtime for three consecutive nights. A seven-day vaginal cream is applied at bedtime for a full week. Most products also include an external cream you can apply to the surrounding skin twice daily for up to seven days to relieve itching and irritation while the internal treatment works.

Shorter courses use a higher concentration of medication per dose, so they’re not necessarily gentler. If you’ve never treated a yeast infection before, the seven-day cream tends to cause fewer localized side effects like burning on application. The one-day and three-day options are more convenient but can feel more intense at the application site.

The Prescription Oral Pill

If you’d rather skip topical treatment entirely, a single 150 mg oral dose of fluconazole is the standard prescription alternative. It’s one pill, one time. Clinical trials show no meaningful difference in outcomes: at two weeks, 94% of patients on the oral pill and 97% on topical therapy were cured or improved. By five weeks, 75% of both groups remained cured.

The oral pill does have a slightly higher rate of mild side effects (27% versus 17% for topical treatment), mostly headache and nausea. But many people prefer it because there’s no mess, no applicator, and no waiting for a cream to absorb. You’ll need a prescription, though some telehealth services can provide one quickly.

How to Tell It’s Actually a Yeast Infection

Treatment only works if you’re treating the right condition. Yeast infections and bacterial vaginosis are commonly confused, but they behave differently. A yeast infection typically produces thick, white, cottage cheese-like discharge with no odor, along with vulvar itching or burning. Vaginal pH stays normal, around 4.0. Bacterial vaginosis, by contrast, causes thin, grayish discharge with a fishy smell that often worsens after sex, and vaginal pH rises above 4.5.

If you’ve had a yeast infection before and recognize the symptoms, self-treating with an OTC antifungal is reasonable. If this is your first time, the symptoms are unusual, or an OTC treatment didn’t work, getting tested helps rule out bacterial vaginosis or other conditions that need different treatment entirely.

Recurrent Yeast Infections

Some people get three or more yeast infections within a single year. This is classified as recurrent, and it requires a different strategy. People with a history of recurrent infections are significantly less likely to respond to a single course of treatment compared to those without that history.

The CDC-recommended approach for recurrent infections is a weekly oral dose of fluconazole for six months. This extended maintenance therapy suppresses the yeast over time and reduces the cycle of repeated flare-ups. It requires a prescription and periodic check-ins, but it’s effective for breaking the pattern.

A newer option called ibrexafungerp, approved by the FDA in 2021, works through a completely different mechanism than traditional antifungals. It received a separate approval in late 2022 specifically for preventing recurrent infections, dosed once monthly. It’s the only FDA-approved antifungal specifically indicated for recurrence and is particularly useful for people who are allergic to traditional antifungals, have drug-resistant strains, or take medications that interact with fluconazole (like certain cholesterol or antidepressant drugs).

Boric Acid Suppositories

Boric acid vaginal suppositories are sometimes recommended when standard antifungals fail. This happens most often with infections caused by less common yeast species that don’t respond well to the usual medications, or with strains that have developed resistance. Clinical studies show mycologic cure rates ranging from 40% to 100%, a wide spread that reflects how much results depend on the specific yeast species involved.

Boric acid is not a first-line treatment. It’s a backup when conventional options have already been tried. It’s also not safe during pregnancy, where a possible link to birth defects has been flagged in early research.

Treatment During Pregnancy

Yeast infections are more common during pregnancy, and the treatment options narrow. Topical antifungal creams and suppositories applied for at least seven days are the recommended first choice. The shorter one-day and three-day courses are less effective during pregnancy, so the full seven-day regimen is preferred.

Topical nystatin is a safe alternative that has been extensively studied in the first trimester. Oral fluconazole is considered second-line during pregnancy. At the standard 150 mg single dose, studies have not found an increased risk of major birth defects, but higher doses (400 mg or more daily) have been linked to malformations in case reports. Most providers will steer toward topical options first.

Do Probiotics Help?

Probiotics containing Lactobacillus strains have shown promising results for preventing yeast infections from coming back, though the evidence is still limited. In one controlled study, the recurrence rate over six months was 7.2% in the probiotic group compared to 35.5% in the placebo group. Another study found recurrence rates of 7% versus 17% shortly after treatment, with placebo-treated patients experiencing more frequent repeat episodes over three months.

Probiotics appear more useful for prevention than for treating an active infection. They won’t clear an existing yeast infection on their own, but adding them after treatment may help reduce the odds of it coming back, particularly if you’re prone to recurrence. The strongest evidence supports vaginal probiotic suppositories used alongside standard antifungal therapy rather than oral probiotic supplements taken alone.
