Most vaginal yeast infections clear up within three to seven days using antifungal medications you can buy at any pharmacy without a prescription. If this is your first infection, or if your symptoms are severe or keep coming back, there are additional steps worth knowing about. Here’s what actually works and what to expect.
Over-the-Counter Treatments
The fastest path to relief is an antifungal cream, ointment, or suppository applied directly in the vagina. The most common active ingredients are clotrimazole (sold as Lotrimin or Mycelex) and miconazole (sold as Monistat). These come in 1-day, 3-day, and 7-day formulations. The shorter courses use a more concentrated dose of the same drug, so the total amount of medication is similar regardless of which length you choose.
A 7-day course tends to be gentler and is often recommended for first-time infections or sensitive skin. The 1-day and 3-day options are more convenient but can cause more local irritation. All of them work by killing the Candida fungus that’s overgrowing in the vagina. You insert the medication at bedtime, usually with an applicator included in the package. Many products also come with an external cream to relieve itching on the vulva while the internal treatment does its work.
When You Need a Prescription
If over-the-counter options don’t resolve your symptoms, or if infections keep returning, a healthcare provider can prescribe a single oral pill. The standard dose is one 150-milligram tablet taken once, and it works from the inside out. This is often preferred by people who find vaginal creams messy or uncomfortable. Symptom relief typically begins within a day or two, though full clearance can take a few days longer.
Prescription-strength vaginal creams are another option. These contain ingredients not available over the counter and are sometimes used for infections caused by less common fungal strains that don’t respond well to standard treatments.
What to Expect During Recovery
With any antifungal treatment, most people notice itching and irritation starting to ease within the first two to three days. Full resolution, including the thick white discharge, typically takes three to seven days. During treatment, it’s best to avoid vaginal intercourse, both because sex can be painful with inflamed tissue and because some cream formulations can weaken latex condoms.
If your symptoms haven’t improved after completing a full course of treatment, that’s a signal to see a healthcare provider. What feels like a yeast infection can sometimes be bacterial vaginosis or another condition entirely. One distinguishing feature: yeast infections keep vaginal pH in the normal range (below 4.5), while bacterial vaginosis raises it. A provider can test for this in minutes.
Recurrent Infections
If you get four or more yeast infections in a single year, that’s considered recurrent. This happens to a significant number of people and doesn’t mean you’re doing something wrong. Recurrent infections sometimes involve non-albicans Candida species, which are harder to treat with standard medications. A provider may take a vaginal culture to identify the exact strain causing your infections, then tailor treatment accordingly.
For recurrent cases, a common approach is a longer initial treatment followed by a maintenance regimen, often a weekly oral antifungal for several months, to suppress the fungus and break the cycle. Boric acid vaginal suppositories are another tool providers sometimes recommend for stubborn or non-albicans infections. These work by restoring the vagina’s natural acidity. They’re inserted at bedtime and are generally well tolerated, but they should never be taken by mouth.
The Role of Probiotics
Probiotics have gotten a lot of attention as a natural approach to yeast infections, and the evidence is nuanced. A large meta-analysis published in the American Journal of Obstetrics and Gynecology found that combining probiotics with standard antifungal treatment improved short-term cure rates and reduced the chance of recurrence at six months. For people with recurrent infections specifically, the combination improved the three-month cure rate significantly.
Probiotics alone, however, don’t perform as well as antifungal drugs for active infections. They were no different from antifungals in the short term but fell behind for long-term fungal clearance. Where probiotics showed the most promise was as a preventive measure: compared to placebo, they significantly improved six-month outcomes for people with recurrent infections. The overall quality of evidence is still low, and researchers haven’t yet identified optimal strains or dosing schedules, so probiotics are best viewed as a possible add-on rather than a replacement for antifungal treatment.
Treatment During Pregnancy
Yeast infections are more common during pregnancy due to hormonal shifts that change the vaginal environment. The good news is that topical antifungal creams and suppositories, including clotrimazole and miconazole, are safe to use at any point during pregnancy. They don’t cause birth defects or pregnancy complications.
Oral antifungal pills are a different story. There’s a possible link between oral antifungals taken during pregnancy, particularly in the first trimester, and miscarriage or birth defects. If you’re pregnant and dealing with a yeast infection, stick with the vaginal creams and suppositories.
Can Your Partner Get It?
Yeast infections aren’t classified as sexually transmitted infections, but the Candida fungus can be passed to a sexual partner. In men, this shows up as redness, swelling, burning, and itching around the head of the penis, sometimes with a thick white discharge or peeling skin. This is called Candida balanitis and is more common in uncircumcised men. If your partner develops these symptoms, they should get their own treatment rather than waiting for it to resolve on its own.
Preventing Future Infections
A few straightforward habits can reduce your risk. Wear cotton underwear and avoid tight-fitting clothing that traps heat and moisture, since Candida thrives in warm, damp environments. Keep the vulvar area clean and dry, changing out of wet swimsuits or sweaty workout clothes promptly. Avoid douching or using scented products in or around the vagina, as these disrupt the natural microbial balance that keeps Candida in check.
Antibiotics are one of the most common triggers for yeast infections because they kill off protective bacteria along with the harmful ones. If you’re on a course of antibiotics and you’re prone to yeast infections, it’s worth discussing preventive options with your provider before symptoms start.
