Thick, white, clumpy discharge that looks like cottage cheese is the hallmark of a vaginal yeast infection, and most cases clear up within a few days to a week with the right antifungal treatment. The infection is caused by an overgrowth of a fungus called Candida albicans that naturally lives in the vagina. You can treat most cases at home with over-the-counter products, though some situations call for a prescription.
Make Sure It’s Actually a Yeast Infection
Before you start treatment, it helps to confirm what you’re dealing with. Yeast infection discharge is thick, white, and odorless, sometimes with a white coating in and around the vagina. Itching, burning, and swelling of the vulva are common alongside the discharge.
Bacterial vaginosis (BV) can look similar at first glance but has key differences. BV discharge tends to be grayish, thinner or foamy, and has a noticeable fishy smell. The treatments for these two conditions are completely different: antifungals for yeast, antibiotics for BV. If your discharge is gray, has an odor, or doesn’t match the classic cottage cheese description, treating it as a yeast infection could delay the right care and let the real problem get worse.
Over-the-Counter Antifungal Options
For a straightforward yeast infection, OTC antifungal creams and suppositories work well. They come in three main formats, and the active ingredient and duration are the biggest differences between them.
- 1-day treatment: Tioconazole 6.5% ointment is a single-use application. You insert it once, and most people start feeling better the next day.
- 3-day treatment: Miconazole is available as a 200 mg suppository (one per night for three nights) or a 4% cream inserted with an applicator daily for three days.
- 7-day treatment: Miconazole also comes in a 100 mg suppository or 2% cream used nightly for a full week. The lower-dose, longer course is gentler and often better tolerated if your skin is already irritated.
All three durations are similarly effective for uncomplicated infections. The choice mostly comes down to preference. Shorter courses are more convenient, but the 7-day option may cause less local irritation. Whichever you pick, finish the full course even if symptoms improve before it’s done.
Prescription Treatment
If OTC products haven’t worked, or if your symptoms are severe, a healthcare provider can prescribe an oral antifungal. Fluconazole is the standard option: a single pill taken by mouth. Many people prefer it because there’s nothing to insert and it treats the infection systemically. For more stubborn infections, a provider may prescribe additional doses spaced a few days apart.
What to Expect During Recovery
Most yeast infections clear up within a few days of starting treatment, though it can take a full week. Severe infections may last longer. Itching and burning typically improve first, followed by the discharge thinning out and returning to normal. During treatment, avoid scented soaps, douching, and sexual intercourse, all of which can irritate already inflamed tissue and slow healing.
Treatment During Pregnancy
Yeast infections are common during pregnancy, and treatment options are more limited. Vaginal creams and suppositories (the same OTC products listed above) are considered safe. Oral antifungals like fluconazole are not recommended during pregnancy, especially in the first trimester, because of a possible link to miscarriage and birth defects. Stick to topical treatments, and let your OB provider know if symptoms don’t resolve.
Boric Acid for Stubborn or Recurring Infections
When standard antifungals don’t fully clear the infection, boric acid vaginal suppositories are an effective second-line option. They work particularly well against atypical yeast species that don’t always respond to the usual treatments. UW Medicine recommends inserting one capsule vaginally each night at bedtime for two weeks to treat an active infection. To prevent recurrence afterward, you can continue using a capsule two nights per week for six to twelve months.
One critical safety point: boric acid is toxic if swallowed. It is only safe when used as a vaginal insert. Keep it away from children, and never take it by mouth.
Why It Keeps Coming Back
If you’re getting four or more yeast infections a year, that’s classified as recurrent vulvovaginal candidiasis, and it needs a different approach than treating each episode individually. A provider will typically confirm the diagnosis with a lab test and may prescribe a longer initial treatment course followed by months of maintenance therapy to keep the fungus from regrowing.
Several factors can fuel recurrence. Antibiotics kill off the protective bacteria that normally keep Candida in check. High blood sugar (from uncontrolled diabetes or a high-sugar diet) feeds yeast growth. Hormonal changes from birth control, pregnancy, or hormone therapy can shift the vaginal environment in yeast’s favor. Identifying and addressing the underlying trigger makes a real difference in breaking the cycle.
Probiotics and Prevention
The vagina is normally dominated by Lactobacillus bacteria, which produce acid and keep yeast populations low. When that balance is disrupted, Candida can overgrow. Probiotic supplements containing specific strains studied for vaginal health, particularly Lactobacillus rhamnosus GR-1, have shown the ability to adhere to vaginal tissue and inhibit harmful organisms. The goal isn’t to colonize the vagina permanently but to help restore the microbial balance that keeps infections from recurring.
Beyond probiotics, practical prevention strategies include wearing breathable cotton underwear, changing out of wet swimsuits or workout clothes promptly, avoiding douches and scented vaginal products, and wiping front to back. None of these cause yeast infections on their own, but together they create conditions that make overgrowth less likely.
