Most vaginal yeast infections clear up within a few days using antifungal creams or suppositories available at any pharmacy without a prescription. Treatment with these antifungal products resolves symptoms and eliminates the infection in 80% to 90% of women who complete the full course. If this is your first infection, your symptoms are severe, or you keep getting them, there are additional options worth knowing about.
Over-the-Counter Antifungal Treatments
The fastest way to start treating a yeast infection is with an OTC antifungal cream or suppository. The two most common active ingredients are miconazole (sold as Monistat) and clotrimazole. Both come in multiple formats: creams you apply inside the vagina, suppositories you insert, and ointments. You’ll find them in 1-day, 3-day, and 7-day courses.
A 3- to 7-day course is the most reliable option. Single-dose suppositories work for some people, but the longer courses give the medication more time to fully clear the overgrowth. The key is finishing the entire course even if your symptoms disappear after a day or two. Stopping early is one of the most common reasons infections come back.
One important safety note: oil-based antifungal creams can weaken latex condoms and diaphragms. They also reduce the effectiveness of vaginal spermicides. If you rely on any of these for birth control or STI protection, they won’t work properly while you’re using the medication.
Getting Relief While You Wait
Antifungals take a couple of days to noticeably reduce symptoms. In the meantime, a cool compress held against the vulva can ease itching and burning. An oral antihistamine like diphenhydramine (Benadryl), taken at night, also helps with itching and has the bonus of making you drowsy enough to sleep through the discomfort. Resist the urge to scratch, because broken skin leads to more irritation and can make the area vulnerable to secondary infection.
While you’re treating the infection, switch to loose-fitting cotton underwear. Avoid tampons, which can absorb the medication and reduce its effectiveness. Holding off on sex until you’ve completed treatment is also a good idea, both for comfort and to avoid interfering with the medication.
Prescription Options
If you prefer a pill over creams and suppositories, a single oral dose of fluconazole (Diflucan) is the standard prescription treatment. It’s one 150 mg pill, taken once. Some people find this more convenient, especially if inserting a cream or suppository is uncomfortable. Fluconazole requires a prescription, so you’ll need to contact a healthcare provider, though many telemedicine services can prescribe it quickly.
For infections that don’t respond to the usual antifungals, prescription-strength vaginal creams like terconazole or butoconazole are another step up. These target a slightly broader range of yeast species and come in both 3-day and 7-day courses.
Boric Acid for Stubborn Infections
Boric acid vaginal suppositories are sometimes used for yeast infections that resist standard antifungal treatment. They work by restoring the natural acid balance in the vagina, creating an environment where yeast can’t thrive. These are inserted vaginally at bedtime and should never be taken by mouth, as boric acid is toxic if swallowed.
Boric acid isn’t a first-line treatment. It’s typically reserved for recurrent or resistant infections, and it’s best used under the guidance of a healthcare provider, especially if you’re pregnant, breastfeeding, or have diabetes or immune system issues. Side effects are usually mild, mostly local irritation at the insertion site. Like oil-based antifungal creams, boric acid can damage latex condoms and diaphragms.
What to Do About Recurring Infections
If you’re getting four or more yeast infections a year, that’s considered recurrent, and it calls for a different approach than treating each episode individually. The typical strategy involves an initial course of antifungal treatment to clear the active infection, followed by a longer maintenance phase of periodic antifungal use to keep the yeast from bouncing back.
There’s also growing evidence that adding a probiotic (containing Lactobacillus strains) to antifungal therapy can help. A meta-analysis of clinical trials found that probiotics improved short-term cure rates by about 14% and, more strikingly, reduced the chance of relapse at one month by 66%. One small study tracked recurrence rates over six months: women taking probiotics alongside antifungals had a 29% recurrence rate, compared to 100% in the group using antifungals alone. The evidence isn’t rock-solid yet, as most of the trials were small, but the pattern is consistent enough to be worth considering if recurrence is your main problem. Both vaginal and oral probiotic capsules have been studied, with Lactobacillus species being the most common strains used.
Make Sure It’s Actually a Yeast Infection
Before you treat, it’s worth confirming what you’re dealing with. Vaginal itching and unusual discharge have several possible causes, and they don’t all respond to the same treatment. Yeast infections produce thick, white, odorless discharge, often described as looking like cottage cheese. You may also notice a white coating in and around the vagina.
Bacterial vaginosis, by contrast, produces thin, grayish, foamy discharge with a noticeable fishy smell. Trichomoniasis causes frothy, yellow-green discharge that smells bad and sometimes has blood spots. Both of these require different medications entirely, so using an antifungal cream won’t help and may delay proper treatment. If your discharge doesn’t match the classic yeast infection pattern, or if OTC treatment isn’t working after a few days, it’s worth getting tested.
When OTC Treatment Isn’t Enough
Some situations warrant skipping the pharmacy aisle and going straight to a provider. Uncontrolled diabetes creates persistently high blood sugar levels that feed yeast growth, making infections harder to clear and more likely to return. Pregnancy is another reason to get professional guidance, both because some treatments aren’t safe during pregnancy and because untreated infections can potentially be passed to the baby during delivery. If you have a weakened immune system for any reason, standard OTC treatments may not be sufficient.
Severe symptoms, like significant swelling, deep fissures in the skin, or pain that goes beyond typical itching and burning, also point toward a more aggressive treatment plan than what’s available over the counter. And if you’ve tried an OTC antifungal for the full recommended course and your symptoms haven’t improved, something else may be going on that needs a proper diagnosis.
