If you have a yeast infection, you can usually treat it yourself with an over-the-counter antifungal cream or suppository from any pharmacy. Most infections clear up within a few days to a week once you start treatment. But before you grab a product off the shelf, it helps to make sure what you’re dealing with is actually a yeast infection, because other vaginal infections look similar and need completely different treatment.
Make Sure It’s Actually a Yeast Infection
The telltale sign is thick, white discharge with a cottage cheese-like texture, along with itching, burning, and irritation around the vulva and vagina. Yeast infections typically don’t produce a noticeable odor. This is an important distinction: bacterial vaginosis, a different and very common vaginal infection, causes thin, grayish-yellow discharge with a strong fishy smell. BV requires antibiotics, so treating it with antifungal cream won’t help.
If this is your first infection, or if your symptoms don’t match the classic pattern, getting a proper diagnosis is worth the trip. A provider will take a small sample of vaginal discharge and examine it under a microscope. It’s quick and straightforward. If you’ve had yeast infections before and recognize the symptoms clearly, you’re generally fine to start OTC treatment on your own.
Over-the-Counter Treatment Options
Antifungal creams and suppositories containing miconazole are the most widely available OTC option. Products like Monistat come in 1-day, 3-day, and 7-day formulations. The active ingredient, miconazole, has been shown to effectively inhibit the growth of Candida albicans, the fungus responsible for most yeast infections. Clotrimazole is another common option you’ll see on pharmacy shelves. Both work well for straightforward infections.
The shorter-duration products use a higher concentration of antifungal per dose, while the 7-day versions spread a lower concentration across more days. They’re all comparably effective. If you have sensitive skin or tend toward irritation, the 7-day version is gentler. Whichever you choose, use the full course even if your symptoms improve before you finish.
Getting Relief While Treatment Works
Antifungal medication doesn’t stop the itching and burning instantly. While you wait for it to kick in, a few things can help. Rinsing the irritated area with a mild saltwater solution (half a teaspoon of salt in a cup of warm water) can soothe inflammation. A thin layer of coconut oil applied to the external skin may reduce dryness and irritation. Wear loose, breathable cotton underwear, and keep the area cool and dry.
Avoid scented soaps, douches, and bubble baths, all of which can worsen irritation. Don’t use tea tree oil directly on the skin without diluting it first, and even then, use it sparingly since it can cause its own irritation and rashes with frequent application.
When You Need a Prescription
If OTC treatment doesn’t resolve your symptoms within a week, or if your symptoms are severe (significant swelling, redness, or cracking of the skin), you likely need something stronger. The standard prescription is a single oral antifungal pill. According to CDC treatment guidelines, this approach clears the infection in 80% to 90% of patients. For severe cases, a second dose 72 hours after the first may be needed.
Pregnancy changes the equation. If you’re pregnant and suspect a yeast infection, talk to your provider before using any treatment, including OTC products. Topical antifungal creams are generally preferred during pregnancy, but the oral pill may carry risks, so your provider will guide you toward the safest option.
What to Do About Recurring Infections
If you’re getting three or more yeast infections per year, that’s considered recurrent. This pattern affects a significant number of people and usually requires a different treatment approach than a one-off infection. The typical protocol involves taking an oral antifungal on days 1, 4, and 7 to clear the active infection, then switching to a weekly maintenance dose for six months to keep the yeast from bouncing back.
For infections caused by less common yeast strains that don’t respond well to standard antifungals, boric acid suppositories are an effective alternative. The standard approach, as outlined by UW Medicine, is one vaginal capsule nightly for two weeks to treat the active infection, then twice weekly for six to twelve months to prevent recurrence. Boric acid capsules are available at most pharmacies, or you can make your own using boric acid powder (not crystals) and size “0” gelatin capsules. This is a treatment to use under your provider’s guidance, not something to experiment with on your own.
Preventing the Next One
Yeast thrives on sugar. High sugar intake feeds Candida growth in the body, so cutting back on simple sugars, white flour, and sugary drinks can reduce your risk. You don’t need to follow a strict elimination diet to see benefits. Even modest reductions in sugar intake can make a difference in how frequently infections occur.
Probiotics containing Lactobacillus strains (particularly L. acidophilus and L. rhamnosus) have shown some promise when used alongside antifungal treatment. Several studies found that combining probiotics with standard antifungal therapy improved outcomes compared to antifungals alone, though the evidence isn’t airtight. One randomized trial found no difference in symptoms at 45 and 90 days. Probiotics are unlikely to hurt and may help, but they’re a supporting player, not a replacement for antifungal treatment.
Other practical steps: change out of wet swimsuits and sweaty workout clothes promptly, avoid sitting in damp clothing for extended periods, choose cotton underwear over synthetic fabrics, and skip scented products in the vaginal area. Antibiotics are one of the most common triggers for yeast infections because they kill the protective bacteria that keep yeast in check. If you’re prone to yeast infections and are prescribed antibiotics for something else, let your provider know so they can plan accordingly.
