If you have a yeast infection, the most effective first step is an over-the-counter antifungal cream or suppository, which clears most infections within one to seven days. About 10% to 20% of cases are more complicated and need a different approach, but the majority resolve with straightforward treatment you can start at home today.
Make Sure It’s Actually a Yeast Infection
Before you treat anything, it helps to confirm what you’re dealing with. Yeast infections have a distinct pattern: thick, white discharge that looks like cottage cheese, intense itching or burning around the vulva, redness and swelling, and sometimes pain during sex or a burning sensation when you pee. Small cuts or tiny cracks in the skin around the vulva are also common.
Bacterial vaginosis, which is frequently confused with a yeast infection, looks and feels different. BV typically produces thin, grayish discharge that’s heavier in volume and has a noticeable odor, especially after your period or after sex. A yeast infection rarely has a strong smell. If your symptoms lean more toward odor and thin discharge than itching and thick discharge, you’re likely dealing with something else that requires a different treatment. Treating the wrong condition wastes time and can make the real problem worse.
If this is your first infection or you’re not sure what’s going on, getting a confirmation from a healthcare provider is worthwhile. They can take a small sample of discharge and identify the exact type of yeast, which matters for choosing the right treatment.
Over-the-Counter Treatments
Antifungal creams and suppositories are available without a prescription at any pharmacy. They come in different treatment lengths: single-dose, three-day, and seven-day options. All of them use antifungal ingredients that work by breaking down the cell walls of the yeast.
Single-dose treatments are convenient but tend to cause more local side effects like burning or irritation at the application site. Three-day and seven-day courses are gentler and equally effective. The seven-day option is often recommended for anyone with sensitive skin or a more stubborn infection. You’ll typically find these as vaginal creams with an applicator or as small suppositories you insert at bedtime.
Most people start feeling relief within two to three days, but it’s important to finish the full course even if symptoms improve earlier. Stopping early can leave enough yeast alive to bounce back.
When You Need a Prescription
A single oral antifungal pill is the main prescription option. It works from the inside out and clears most uncomplicated infections with one dose. Some people prefer it because there’s no messy cream to deal with.
However, not everyone should take it. If you’re pregnant, oral antifungals are off the table entirely. Studies have linked even a single dose to an increased risk of miscarriage and birth defects. During pregnancy, only topical creams or suppositories are recommended, applied for a full seven days.
If you have diabetes, HIV, or are on medications that suppress your immune system (like corticosteroids), standard short treatments often don’t work well enough. These conditions make it harder for your body to help fight off the yeast, so a longer course of 7 to 14 days is typically necessary. Getting blood sugar under control, if that’s a factor, also makes a real difference in how well treatment works and whether the infection comes back.
What to Do for Comfort Right Now
While the antifungal does its job, a few things can ease the itch and irritation. Keep the area clean and dry, but skip scented soaps, douches, and bubble baths, all of which can worsen inflammation. Wash with plain water or a mild, unscented cleanser. Wearing cotton underwear and loose, breathable clothing reduces moisture buildup, which is the environment yeast thrives in. Tight synthetic fabrics trap heat and sweat against the skin, making symptoms worse.
A cool compress against the vulva can temporarily calm intense itching. Avoid scratching, which can break the skin and open the door to a secondary bacterial infection on top of the yeast.
Boric Acid Suppositories
You may have seen boric acid suppositories marketed for yeast infections. They’re sometimes used for infections that resist standard antifungals, particularly strains of yeast that aren’t the most common type. Some clinicians prescribe them as a maintenance therapy for women with frequent recurrences, typically at a dose of 300 to 600 milligrams inserted vaginally two to three times per week after an initial daily course.
There are important caveats. Boric acid is not FDA-approved for this use, and long-term safety data are limited. It’s absorbed minimally through vaginal tissue, but it is toxic if swallowed, and it should never be used during pregnancy because of potential harm to the developing baby. If you’re considering boric acid, it’s best used under the guidance of a provider who can monitor your response.
Probiotics as a Complement
Certain probiotic strains can improve how well antifungal treatment works. In a randomized, placebo-controlled trial, women who took specific lactobacillus probiotics alongside their antifungal medication had significantly better outcomes than those who used the antifungal alone. Lab research has shown that these bacteria produce lactic acid at a low pH, which directly suppresses yeast growth and can even kill the fungus. They also appear to reduce the yeast’s ability to resist antifungal medication.
Probiotics aren’t a replacement for antifungal treatment, but they can support recovery and help restore the balance of healthy bacteria in the vagina afterward. Look for products that contain strains specifically studied for vaginal health rather than general gut-health formulas.
Preventing the Next One
Some people get one yeast infection and never deal with it again. Others find them recurring. A few habits lower your risk considerably:
- Wear cotton underwear and avoid sitting in wet swimsuits or sweaty workout clothes. Yeast grows fastest in warm, damp environments.
- Skip scented products near the vagina, including scented tampons, pads, sprays, and wipes. These can disrupt the natural pH balance that keeps yeast in check.
- Change out of damp clothing quickly after swimming or exercising.
- Avoid unnecessary antibiotics. Antibiotics kill the beneficial bacteria that normally keep yeast populations low, which is why yeast infections commonly follow a course of antibiotics for something else entirely.
If you’re getting four or more yeast infections per year, that qualifies as recurrent and warrants a conversation with a provider. Recurrent infections sometimes signal an underlying issue like undiagnosed diabetes or an immune condition, and they often require a longer, more structured treatment plan rather than repeated rounds of the same short-course therapy.
