Most yeast infections are cured with antifungal medication, either an over-the-counter vaginal cream or suppository or a single prescription pill. Treatment clears symptoms and eliminates the fungus in 80% to 90% of people who complete it. Mild infections often improve within a few days, though a full course can take up to a week or longer for severe cases.
Over-the-Counter Treatments
The fastest way to start treating a yeast infection is with an antifungal cream or suppository from a pharmacy. No prescription is needed. The two most common active ingredients are clotrimazole and miconazole, both available as creams or vaginal suppositories. These work by blocking a key building block in the fungal cell membrane, essentially poking holes in the yeast until it dies.
You have options depending on how quickly you want to finish treatment:
- 1-day treatments: A single high-dose miconazole suppository (1,200 mg) or a single application of tioconazole ointment.
- 3-day treatments: Miconazole or clotrimazole cream applied nightly for three nights, or a miconazole suppository used for three nights.
- 7-day treatments: A lower-concentration cream (miconazole 2% or clotrimazole 1%) applied nightly for a full week, sometimes extended to 14 days for stubborn infections.
Shorter courses use higher concentrations of medication. They’re equally effective for straightforward infections, so the choice comes down to personal preference. Many people notice itching and irritation start to ease within the first day or two, but it’s important to finish the full course even if symptoms improve early.
The Prescription Pill Option
Fluconazole is an oral antifungal available by prescription. A single 150 mg dose is the standard treatment for an uncomplicated yeast infection. For many people, this is the most convenient option: one pill, and you’re done. It works the same way as the topical creams, just from the inside out.
For severe infections with intense redness, swelling, or cracking of the skin, a second dose taken 72 hours after the first is typically recommended. Prescription-only vaginal creams like terconazole are another option your provider might suggest, particularly if fluconazole isn’t a good fit for you.
How Long Recovery Actually Takes
Most yeast infections clear up within a few days of starting medication, but complete resolution can take a full week. Severe cases may take longer. You’ll likely feel the most relief from itching and burning in the first two to three days. Discharge and any remaining irritation usually resolve over the following days as the fungal population dies off.
If your symptoms haven’t improved at all after three days of treatment, or they come back shortly after finishing, the infection may not actually be caused by yeast. That’s worth knowing, because the symptoms overlap with other conditions that require different treatment entirely.
Making Sure It’s Actually a Yeast Infection
About two-thirds of people who self-diagnose a yeast infection are wrong. The classic symptom is thick, white, cottage cheese-like discharge with intense itching. But bacterial vaginosis, a completely different condition, can look similar at first glance. BV tends to produce thinner, grayish discharge with a noticeable fishy odor, especially after your period or after sex. Yeast infections rarely have a strong odor.
The distinction matters because antifungal creams do nothing for BV, and BV requires antibiotics. If you’ve never had a confirmed yeast infection before, or if over-the-counter treatment isn’t working, getting tested gives you a clear answer. A provider can check vaginal pH and look at a sample under a microscope to tell the difference quickly.
What to Do About Recurring Infections
If you get four or more yeast infections in a year, you’re dealing with recurrent vulvovaginal candidiasis. This affects a significant number of people and requires a different treatment strategy than a one-off infection.
The standard approach has two phases. First, a longer initial course to fully knock out the fungus: either 7 to 14 days of topical treatment or three oral doses of fluconazole spread over a week (taken on days 1, 4, and 7). Once the active infection is cleared, a maintenance phase begins. This means taking a weekly oral dose of fluconazole for six months. The goal is to suppress the yeast long enough for the vaginal environment to stabilize.
This extended protocol works well for most people, but it requires commitment. Stopping maintenance early often leads to another flare-up.
When Standard Treatment Doesn’t Work
Most yeast infections are caused by a species called Candida albicans, which responds reliably to all the standard antifungals. But a smaller percentage are caused by other Candida species that may not respond to fluconazole at all. If you’ve been treated and the infection keeps coming back, your provider may test to identify the exact species.
For these resistant infections, boric acid vaginal suppositories are the go-to alternative. The standard regimen is a 600 mg boric acid capsule inserted vaginally at bedtime for two to three weeks. Some providers then recommend continuing with twice-weekly use for 6 to 12 months to prevent recurrence. Boric acid capsules can be purchased at pharmacies or made at home using boric acid powder (not crystals) packed into size “0” gelatin capsules. These are for vaginal use only and should never be taken by mouth.
Probiotics and Prevention
The vagina naturally maintains a slightly acidic environment dominated by Lactobacillus bacteria. These bacteria keep yeast populations in check. When that balance is disrupted, whether by antibiotics, hormonal changes, or other factors, yeast can overgrow.
Probiotic strains like Lactobacillus rhamnosus GR-1 have been studied for their ability to restore vaginal flora and reduce recurrence of vaginal infections. The evidence is promising but not yet strong enough to call probiotics a standalone treatment. They’re better thought of as a supporting strategy alongside antifungal medication, particularly for people prone to recurrent infections.
Practical steps that help prevent yeast infections include wearing breathable cotton underwear, avoiding scented products in the vaginal area, changing out of wet swimwear or workout clothes promptly, and being aware that antibiotics can trigger a yeast overgrowth. If you know antibiotics are a trigger for you, your provider may prescribe a preventive dose of fluconazole to take alongside your antibiotic course.
