Most uncomplicated yeast infections clear up within three to seven days using an over-the-counter antifungal cream or a single prescription pill. The treatment you choose depends on your preference, whether you’re pregnant, and whether this is a one-time infection or a recurring problem.
Over-the-Counter Antifungal Treatments
The fastest way to start treating a yeast infection at home is with a topical antifungal available at any pharmacy without a prescription. These come as creams, ointments, tablets, or suppositories that you insert into the vagina. The most common active ingredients are miconazole (sold as Monistat) and clotrimazole. Regimens range from a single-day high-dose treatment to a seven-day course, and they all work similarly well for straightforward infections.
You can expect itching and burning to start improving within the first day or two, though you should finish the full course even if symptoms fade early. Stopping treatment too soon is one of the most common reasons an infection seems to come back.
Prescription Options
If you’d rather skip the creams, a single 150 mg dose of oral fluconazole does the job with an average cure rate around 84%. Your doctor can call it in without an office visit in many cases. It works systemically, reaching vaginal tissue through the bloodstream, so there’s nothing to insert.
For severe infections with intense redness, swelling, or skin cracking, a longer course of oral fluconazole (two to three doses spread over several days) or a 7- to 14-day topical regimen is typically needed. Severe infections take longer to resolve, sometimes up to two weeks before symptoms fully disappear.
Yeast Infection During Pregnancy
If you’re pregnant, topical antifungal creams and suppositories are the standard choice. Oral fluconazole is generally avoided during pregnancy, especially at high doses or over extended periods, because of a potential risk to fetal development. The FDA notes that available human data don’t suggest increased risk from a single low dose, but most providers still recommend sticking with topical treatments to be safe. A seven-day course of a cream like miconazole is the usual recommendation.
What to Do if It Keeps Coming Back
Recurrent yeast infections, defined as three or more episodes in a single year, affect fewer than 5% of women. If that sounds like your pattern, over-the-counter treatments alone probably won’t break the cycle.
Boric acid vaginal suppositories are one of the more effective options for recurrent or treatment-resistant infections, particularly those caused by less common yeast species. The typical protocol from UW Medicine is one capsule inserted vaginally each night for two weeks to clear the active infection, then twice a week for six to twelve months to prevent recurrence. Boric acid is toxic if swallowed, so it’s only used as a vaginal suppository and should be kept away from children.
Your doctor may also prescribe a maintenance regimen of oral fluconazole, usually one dose per week for six months, to suppress recurrence. Either approach requires medical guidance rather than self-treatment.
Make Sure It’s Actually a Yeast Infection
About two-thirds of women who self-diagnose a yeast infection are wrong. Bacterial vaginosis (BV) is the most common lookalike, and the treatments are completely different. A few key differences can help you tell them apart.
Yeast infections produce a thick, white, cottage cheese-like discharge and cause significant itching, burning, and pain, especially during intercourse. BV produces a thinner, grayish discharge that tends to be heavier in volume and has a noticeable fishy odor, particularly after your period or after sex. BV can cause irritation, but it rarely causes the sharp pain that yeast infections do. If your symptoms don’t match the typical yeast infection pattern, or if an OTC antifungal doesn’t improve things within a few days, getting a proper diagnosis matters before you keep treating the wrong condition.
Habits That Help Prevent Recurrence
Yeast thrives in warm, moist environments with plenty of sugar to feed on. A few practical changes can make your body less hospitable to overgrowth.
- Clothing choices: Wear cotton underwear and avoid sitting in wet swimsuits or sweaty workout clothes. Tight, non-breathable fabrics trap moisture against the skin.
- Hygiene basics: Skip douches, scented sprays, and perfumed soaps in the vaginal area. These disrupt the natural bacterial balance that keeps yeast in check.
- Diet: Diets high in simple sugars reduce the diversity of your gut microbiome and may promote fungal overgrowth. Increasing your intake of fiber, vegetables, and omega-3 fatty acids supports a healthier microbial balance overall. This won’t cure an active infection, but it can lower your baseline risk over time.
Do Probiotics Work?
Probiotic supplements containing Lactobacillus strains are widely marketed for vaginal health, and the logic seems sound: healthy vaginal flora is dominated by Lactobacillus, so replenishing it should help fight yeast. In practice, the clinical evidence is still inconclusive. Some small studies have shown reduced recurrence rates, but larger, more rigorous trials have found no significant difference between probiotics and placebo. The studies that do show benefits tend to have small sample sizes and design flaws that make the results unreliable. Probiotics are unlikely to cause harm, but they shouldn’t replace antifungal treatment for an active infection.
