Most yeast infections clear up within a few days to two weeks using over-the-counter antifungal creams or a single prescription pill. The type of yeast infection you have, where it is on your body, and whether it keeps coming back all determine the best approach. Here’s what works, how long each option takes, and what to do if the infection won’t go away.
Why Yeast Overgrows in the First Place
Your body naturally carries a yeast called Candida albicans, the most common species behind yeast infections. Normally, the bacteria in your microbiome keep it in check. But when something disrupts that balance, the yeast multiplies faster than your body can control it, and you end up with an infection.
Common triggers include antibiotics (which kill off the helpful bacteria that suppress yeast), a weakened immune system, hormonal shifts like pregnancy, uncontrolled blood sugar, and staying in damp clothing too long. Understanding what tipped the balance for you can help prevent the next round.
Over-the-Counter Treatments for Vaginal Yeast Infections
For a straightforward vaginal yeast infection, antifungal creams and suppositories sold without a prescription are the standard first step. You have several options based on how quickly you want to finish treatment:
- 1-day options: A single high-dose miconazole suppository or a single application of tioconazole ointment.
- 3-day options: A higher-concentration miconazole or clotrimazole cream used nightly for three days, or a miconazole suppository for three nights.
- 7-day options: A lower-concentration miconazole or clotrimazole cream applied nightly for a full week. This gentler approach is the only recommended option during pregnancy.
Shorter courses use higher concentrations of the same active ingredient, so the total amount of medication is roughly equivalent. Pick the schedule that fits your preference. All of these products are applied at bedtime for best absorption, and you should avoid relying on condoms or diaphragms during treatment because the medication can weaken them.
Prescription Options
If you’d rather skip the creams entirely, a single 150-mg fluconazole tablet taken by mouth is the most common prescription alternative. It’s convenient, and clinical data across 13 trials with over 1,800 patients shows oral and topical antifungals perform nearly identically: about 79% and 77% cure rates, respectively, in the short term. With longer courses, both approaches climb to roughly 85%. The CDC considers them equivalent for uncomplicated infections.
Prescription creams and suppositories also exist for people who don’t respond to OTC products. These use different antifungal compounds and are typically applied for three to seven days.
Treating Oral Thrush
Yeast infections in the mouth and throat, known as thrush, look like white patches on the tongue, inner cheeks, or roof of the mouth. Mild to moderate cases are treated with an antifungal gel applied inside the mouth for 7 to 14 days. More severe infections may require a prescription antifungal pill. Thrush is more common in people with weakened immune systems, denture wearers, and those using inhaled corticosteroids for asthma.
Skin Yeast Infections
Yeast thrives in warm, moist skin folds: under the breasts, in the groin, between fingers, and in armpit creases. These infections typically show up as a red, itchy rash, sometimes with small satellite spots around the edges. Keeping the area clean and completely dry is just as important as any antifungal cream you apply. Most OTC antifungal powders or creams containing clotrimazole or miconazole will clear a skin yeast infection within one to two weeks.
What to Do When It Keeps Coming Back
If you get four or more vaginal yeast infections in a single year, that’s classified as recurrent vulvovaginal candidiasis, and it needs a different strategy. The initial treatment phase is longer: 7 to 14 days of a topical antifungal, or three oral doses spread over a week (taken on days 1, 4, and 7). After that, a weekly oral antifungal dose for six months is the standard maintenance regimen to keep the yeast from bouncing back.
Some recurrent infections are caused by a less common yeast species that doesn’t respond well to fluconazole. In those cases, a different antifungal cream or suppository used for 7 to 14 days is the first line. If it recurs again, boric acid vaginal suppositories used once daily for three weeks are an established backup option recommended by the CDC. Boric acid is never taken by mouth and should not be used during pregnancy.
Probiotics as a Complement
There’s growing interest in using probiotics to restore the bacterial balance that keeps yeast in check. One randomized trial tested a specific Lactobacillus strain delivered as a vaginal capsule and found it reduced yeast infection symptoms at rates comparable to a standard antifungal product, with improvements maintained through three weeks of follow-up. That’s promising, but probiotics work best as a complement to proven antifungal treatment or as a preventive measure between infections, not as a standalone replacement when you have active symptoms.
Make Sure It’s Actually Yeast
About two-thirds of women who self-treat for a yeast infection actually have something else going on. The symptoms overlap significantly with bacterial vaginosis, which requires a completely different treatment. A useful way to tell them apart: yeast infections produce thick, white, odorless discharge, often with a white coating in and around the vagina. Bacterial vaginosis typically causes thinner, grayish, foamy discharge with a fishy smell, though it can also be symptomless. If your OTC antifungal doesn’t start improving things within a few days, the diagnosis is likely wrong and you’ll need testing to figure out what’s actually happening.
Preventing the Next Infection
A few simple habits reduce your risk of yeast overgrowth. Wear cotton underwear and breathable, not-too-tight clothing, especially in warm weather or during exercise. Change out of wet swimsuits and sweaty workout clothes promptly. Keep the vaginal area clean and dry, but skip douches, scented sprays, and scented tampons, all of which disrupt the natural bacterial balance that holds yeast in check.
If you’re on antibiotics, be aware that they’re one of the most common triggers. You can’t always avoid them, but knowing the connection lets you watch for early symptoms and treat quickly rather than waiting until the infection is fully established. People with diabetes can reduce their risk by keeping blood sugar well controlled, since yeast feeds on sugar and thrives when levels run high.
