Most vaginal yeast infections clear up within a few days to two weeks using antifungal medications, many of which are available without a prescription. Over-the-counter antifungal creams and suppositories cure uncomplicated yeast infections in 80 to 90 percent of cases. For stubborn or recurring infections, prescription options and longer treatment plans can help.
Over-the-Counter Antifungal Treatments
The fastest way to treat a straightforward yeast infection is with an OTC antifungal cream or suppository. These products contain antifungal compounds that stop the overgrowth of Candida, the fungus responsible for the infection. You’ll find them at any pharmacy under brand names like Monistat, and they come in different treatment lengths depending on the strength.
Miconazole is one of the most popular options. A 2% cream is applied daily for seven days, while a 4% cream shortens the course to three days. Suppository versions follow the same pattern: a lower-dose suppository used nightly for seven days, a mid-dose version for three days, or a single high-dose suppository for a one-day treatment. Clotrimazole works similarly, with a 1% cream used for seven to fourteen days or a 2% cream for three days.
If you want the shortest possible treatment, tioconazole ointment requires only a single application. All of these products are inserted vaginally, and most people start feeling relief within a day or two, though you should finish the full course even if symptoms improve early. Stopping treatment too soon is one of the most common reasons infections come back.
Prescription Treatment for Tougher Cases
When OTC products don’t work, or if you’d rather skip the creams entirely, a doctor can prescribe a single oral antifungal pill. The standard dose is 150 milligrams taken just once. It’s convenient and effective for most uncomplicated infections.
Oral antifungal pills aren’t right for everyone, though. If you’re pregnant, especially in the first trimester, this medication can harm the developing baby. People with liver disease also need to use it cautiously, since it can worsen liver problems in rare cases. For these situations, your doctor will likely recommend a topical treatment instead.
What to Do About Recurring Infections
If you get four or more yeast infections in a year, you’re dealing with recurrent infections, and the standard short-course treatments won’t be enough on their own. The CDC recommends a two-phase approach for recurrent cases. First, a longer initial treatment to fully clear the infection: either seven to fourteen days of a topical antifungal, or three doses of an oral antifungal spaced out over a week (on days one, four, and seven). Once the infection is gone, you move into a maintenance phase of one oral dose per week for six months.
This extended regimen works well for most people, but it requires a prescription and follow-up with a healthcare provider. The goal is to suppress the yeast long enough for your body’s natural balance to stabilize.
Boric Acid for Resistant Strains
Some yeast infections are caused by less common fungal species that don’t respond well to standard antifungals. For these resistant infections, boric acid vaginal suppositories are a well-supported alternative. UW Medicine describes boric acid as “an excellent therapy” for recurrent infections or those caused by atypical strains.
The typical treatment involves inserting one capsule vaginally each night for two weeks. To prevent recurrence after that, you can use a capsule twice a week (spaced a few days apart) for six to twelve months. Boric acid capsules are available over the counter, but this is a treatment best used with guidance from a provider, since boric acid is toxic if swallowed and should never be taken orally.
Do Probiotics Help?
Probiotics containing Lactobacillus bacteria have shown genuine promise, particularly for preventing recurrence rather than treating an active infection on their own. A meta-analysis published in the American Journal of Obstetrics & Gynecology found that probiotics significantly outperformed placebo for achieving a six-month cure in women with recurrent yeast infections. The effect was notable: women using probiotics were roughly twelve times more likely to remain infection-free at six months compared to those on placebo.
That said, the evidence is still considered low-certainty, meaning the results are encouraging but based on small studies. Probiotics are best thought of as a complement to antifungal treatment rather than a replacement, especially for an active infection that’s causing symptoms right now.
Home Remedies to Approach With Caution
Tea tree oil is one of the most commonly searched home remedies for yeast infections, but it comes with real risks. Applying any essential oil to irritated or raw vaginal tissue can cause stinging, burning, and contact reactions. Some tea tree oil products contain compounds that are particularly harsh on abraded tissue. If you’re already dealing with the soreness and swelling of a yeast infection, adding an irritant can make things significantly worse.
Other popular remedies like garlic, apple cider vinegar, and coconut oil lack strong clinical evidence and carry their own risks of irritation or disrupting vaginal pH. Given that proven OTC antifungals are inexpensive and widely available, there’s little reason to experiment with unproven alternatives for an active infection.
Preventing Yeast Infections From Coming Back
Yeast thrives on sugar. Uncontrolled blood sugar, whether from diabetes or consistently high sugar intake, feeds Candida growth in the vaginal environment. Getting blood sugar under control is one of the most impactful changes for people who deal with frequent infections. You don’t necessarily need to eliminate sugar entirely. Even modest reductions in simple sugars can reduce the frequency and severity of infections.
Other practical steps that lower your risk include wearing breathable cotton underwear, changing out of wet swimsuits or workout clothes promptly, and avoiding scented products near the vaginal area (douches, scented tampons, perfumed soaps). Antibiotics are another common trigger, since they kill the protective bacteria that keep yeast in check. If you notice infections tend to follow antibiotic courses, talk to your provider about using a preventive antifungal dose alongside your next prescription.
