If you think you have a yeast infection, the most effective first step depends on whether you’ve had one before and been diagnosed by a healthcare provider. For a straightforward, first-time infection, you’ll want a proper diagnosis before treating it. If you’ve had a confirmed yeast infection in the past and recognize the same symptoms, over-the-counter antifungal treatments are widely available and work well for most people. Most infections clear up within a few days to a week with treatment.
Make Sure It’s Actually a Yeast Infection
This step matters more than most people realize. Research from the American Academy of Family Physicians found that only 34% of women who believed they had a yeast infection actually had one. The majority of women purchasing OTC yeast infection treatments didn’t have that condition at all, even those with previous experience diagnosing themselves.
Yeast infection discharge is typically thick, white, and odorless, often described as resembling cottage cheese. You may also notice a white coating in and around the vagina. The hallmark symptoms are intense itching, burning, and swelling of the vulva. Sex can be painful, and urination may sting if the skin is irritated.
Two other common conditions look similar but require completely different treatment. Bacterial vaginosis produces grayish, foamy discharge with a noticeable fishy smell, though it sometimes has no symptoms at all. Trichomoniasis causes frothy, yellow-green discharge that smells bad and may contain spots of blood. Treating either of these with an antifungal won’t help and delays the treatment you actually need. If your symptoms don’t match the classic yeast infection pattern, or if this is your first time experiencing them, getting tested is the smart move.
Over-the-Counter Antifungal Options
The main OTC treatments are vaginal creams, ointments, and suppositories containing antifungal medications. They come in 1-day, 3-day, and 7-day regimens. The shorter treatments use higher concentrations of medication, while the 7-day versions use lower doses spread over more time. Clinical trials comparing single-dose and 3-day treatments show similar results: about 84 to 85% of patients remained symptom-free four weeks after treatment regardless of which regimen they used.
The 7-day option tends to be gentler and may cause less local irritation, making it a good choice if you’ve had sensitivity to the more concentrated formulas. Any of the three durations will work for an uncomplicated infection. Whichever you choose, finish the full course even if your symptoms improve before the treatment is done. Stopping early increases the chance of the infection coming back.
Recurrence rates for yeast infections range from 10 to 40% regardless of treatment type, so don’t be surprised if symptoms return weeks or months later.
Prescription Treatment
If you’d rather skip the creams, a single oral antifungal pill is the prescription alternative. The standard dose for an uncomplicated yeast infection is a single 150 mg tablet. It’s convenient because there’s nothing to insert and only one dose to remember. Most infections respond to either oral or topical treatment within a few days, though more severe cases can take longer.
Your provider may recommend the oral option if topical treatments haven’t worked, if your symptoms are more severe, or if you simply prefer it. For recurrent infections (three or more in a year, which affects fewer than 5% of women), a provider will typically set up a longer maintenance plan rather than treating each episode individually.
What to Do Right Now for Comfort
While your treatment is working, a few things can ease the discomfort. Switch to cotton underwear and loose, breathable clothing. Tight fabrics trap moisture and warmth, which is exactly the environment yeast thrives in. Keep the area clean and dry, but avoid douching, scented soaps, or any fragranced products near the vulva. These disrupt the natural balance of bacteria and can make things worse.
Cool water rinses can soothe external itching. Avoid sex until the infection clears, both for your own comfort and because some topical treatments can weaken latex condoms and diaphragms.
Probiotics as a Supplement
There’s growing interest in using probiotics alongside antifungal treatment, particularly for people who get recurrent infections. A Cochrane review of five trials found that adding probiotics to standard antifungal therapy increased short-term cure rates. A separate double-blind trial found that women with recurrent infections who took an oral probiotic containing Lactobacillus strains alongside their antifungal treatment had fewer recurring symptoms of itching and discharge over the following months.
The evidence is still modest, and probiotics alone won’t treat an active infection. But if you’re dealing with frequent recurrences, adding a Lactobacillus-based probiotic to your routine is low-risk and may help tip the balance in your favor over time.
Boric Acid Suppositories
Boric acid vaginal suppositories (600 mg, used once daily) are sometimes recommended as a second-line option, particularly for infections that haven’t responded to standard antifungals or for certain resistant yeast strains. Phase 3 clinical trials are currently evaluating their safety and efficacy more rigorously. They should never be taken orally, as boric acid is toxic when swallowed. They’re also not appropriate during pregnancy or breastfeeding. If standard treatments aren’t working for you, this is worth discussing with a provider rather than trying on your own.
Reducing Your Risk of Future Infections
The CDC recommends three straightforward habits to lower your risk: wear cotton underwear, choose breathable clothing that isn’t too tight, and keep the vulvar area clean and dry. Beyond that, change out of wet swimsuits and sweaty workout clothes promptly. Avoid scented tampons, pads, and sprays. Antibiotics are one of the most common triggers for yeast infections because they kill off the protective bacteria that keep yeast in check, so if you notice a pattern after antibiotic courses, let your provider know.
High blood sugar also promotes yeast overgrowth. People with poorly controlled diabetes are at higher risk for recurrent infections, and getting blood sugar under better control often reduces their frequency.
