Most vaginal yeast infections clear up within a few days using antifungal medications available over the counter at any pharmacy. The standard options come in 1-day, 3-day, and 7-day formulations, and all are effective for uncomplicated infections. For stubborn or recurring cases, a prescription oral antifungal can work as a single dose.
Recognizing a Yeast Infection
The hallmark symptom is intense itching and irritation around the vulva and vaginal opening. Most people also notice a thick, white discharge that looks like cottage cheese and has little or no odor. Burning during urination or sex, redness, and swelling of the vulva are also common. If you’ve had a yeast infection before and recognize these symptoms, you can reasonably start over-the-counter treatment on your own. A first-time infection, or one that doesn’t match these typical signs, is worth getting checked by a healthcare provider, since bacterial vaginosis and some sexually transmitted infections can look similar but require different treatment.
Over-the-Counter Antifungal Treatments
Pharmacy antifungals come as vaginal creams, suppositories, or a combination of both. The most widely used active ingredients are miconazole (sold as Monistat) and clotrimazole (sold as Lotrimin or Mycelex). You’ll see them labeled by treatment length:
- 1-day treatment: A single high-dose suppository inserted once.
- 3-day treatment: A suppository inserted at bedtime for three consecutive nights.
- 7-day treatment: A lower-dose vaginal cream applied at bedtime for seven nights in a row.
Shorter courses use a higher concentration of medication per dose, so they’re not necessarily “stronger” or more effective. The 7-day cream tends to cause less local irritation because the dose is spread out, which makes it a good choice if your skin is already very inflamed. Many people feel noticeable relief from itching within a day or two of starting treatment, but it’s important to finish the full course even if symptoms improve early. Stopping too soon can leave enough yeast behind to cause a rebound.
One practical tip: insert the cream or suppository right before bed, and consider wearing a panty liner. Gravity and body heat can cause some of the medication to leak out during the day if you apply it in the morning.
Prescription Treatment
If you’d rather skip the vaginal creams, a healthcare provider can prescribe fluconazole, an oral antifungal taken as a single 150-milligram pill. It works systemically, reaching the vaginal tissue through the bloodstream. Most people see symptoms start to resolve within a day or two, though full clearance can take up to 72 hours. Fluconazole is particularly convenient for people who find vaginal application uncomfortable or impractical.
For complicated infections, those that are severe, caused by a less common yeast species, or occurring in someone with a weakened immune system, the treatment course is longer. A provider may prescribe multiple doses of fluconazole spaced days apart, or recommend a longer course of topical antifungals.
Treatment During Pregnancy
If you’re pregnant, stick with vaginal creams or suppositories rather than oral medication. Products containing clotrimazole or miconazole are safe to use at any point during pregnancy and don’t cause birth defects or pregnancy complications. Oral fluconazole, on the other hand, has a possible link to miscarriage and birth defects, especially during the first trimester. The 7-day topical course is generally the preferred option during pregnancy because it’s the gentlest on already-sensitive tissue.
What About Home Remedies?
You’ll find plenty of suggestions online for treating yeast infections with yogurt, tea tree oil, garlic, coconut oil, or apple cider vinegar. None of these have strong clinical evidence behind them, and some can irritate the vaginal lining or disrupt its natural bacterial balance, potentially making things worse. Boric acid vaginal suppositories are sometimes recommended by providers for infections that don’t respond to standard antifungals, but they’re not a first-line remedy and shouldn’t be used without guidance.
Probiotics are another popular suggestion. While Lactobacillus bacteria play a key role in maintaining vaginal health, clinical trials testing probiotic supplements for treating or preventing yeast infections have not demonstrated clear effectiveness. Small studies show some promise, but nothing strong enough to recommend them as a replacement for antifungal treatment. There’s no harm in eating yogurt with live cultures or taking a probiotic supplement, but don’t rely on it to clear an active infection.
Preventing Yeast Infections From Coming Back
Some people get a yeast infection once and never deal with it again. Others find themselves in a frustrating cycle of recurrence. Three or more infections within a single year qualifies as recurrent vulvovaginal candidiasis, which affects fewer than 5% of women but can significantly impact quality of life. If that describes your experience, a healthcare provider can set up a longer-term antifungal regimen to break the cycle.
Day-to-day habits do influence your risk. Yeast thrives in warm, moist environments, so these changes can help:
- Wear breathable underwear. Cotton is better than synthetic fabrics. Change out of wet swimsuits or sweaty workout clothes as soon as you can.
- Avoid irritating products. Scented tampons, douches, vaginal sprays, and bubble baths can disrupt the vaginal environment. Plain water is enough for external cleaning.
- Manage blood sugar. Uncontrolled diabetes creates higher sugar levels throughout the body, which feeds yeast growth. Keeping blood sugar well-managed makes a real difference in infection frequency.
- Watch your diet. Yeast feeds on sugar. Reducing your intake of simple sugars, white flour, and white rice may help lower the frequency or severity of infections. You don’t need to eliminate these foods entirely. Even cutting back moderately can have a positive effect.
- Be mindful with antibiotics. Antibiotics kill the beneficial bacteria that keep yeast in check, which is why yeast infections often show up during or right after an antibiotic course. If you’re prone to yeast infections, ask your provider about a preventive antifungal to take alongside antibiotics.
When Treatment Isn’t Working
If you’ve completed a full course of over-the-counter treatment and your symptoms haven’t improved after a week, the problem may not be a yeast infection. Bacterial vaginosis, contact dermatitis, and certain STIs can mimic yeast infection symptoms. It’s also possible you have an infection caused by a less common yeast species, like Candida glabrata, which doesn’t always respond to standard antifungals. In either case, a provider can do a vaginal swab to identify exactly what’s going on and adjust your treatment accordingly.
