Most yeast infections clear up within a few days to a week with the right treatment, and you have several effective options ranging from over-the-counter creams to prescription pills. Stopping a yeast infection means both treating the current episode and making changes that keep it from coming back.
Treating a Current Yeast Infection
If this is your first yeast infection, or you get them only occasionally, an antifungal cream or suppository from the drugstore is the standard first step. These products come in one-day, three-day, and seven-day courses. The shorter courses use a higher concentration of the same active ingredient, so effectiveness is similar. Many people notice symptom relief within the first couple of days, but you should finish the full course even if you feel better sooner.
A single-dose prescription pill is the other common option. It works systemically rather than locally, and most people find it more convenient. Your provider can often call it in without an office visit if you’ve had confirmed yeast infections before. More severe infections, where redness and swelling are significant or symptoms have been building for a while, may take longer to resolve and sometimes require a second dose or extended treatment.
What to Do if It Keeps Coming Back
Recurrent yeast infections are defined as four or more episodes in a single year, or three episodes that aren’t triggered by antibiotics. If that sounds familiar, you’re dealing with a pattern that simple one-off treatments won’t break.
The standard approach for recurrent infections is a longer course of the same antifungal pill, followed by a maintenance dose taken weekly or biweekly for several months. This suppressive strategy gives your vaginal environment time to stabilize. Some people stay on maintenance therapy for six months or longer.
Boric acid suppositories are another well-supported option, particularly for infections caused by less common yeast strains that don’t respond well to standard antifungals. UW Medicine recommends using one capsule vaginally each night for two weeks to treat an active infection, then tapering to twice a week for six to twelve months to prevent recurrence. Boric acid capsules can be purchased pre-made or filled at home using boric acid powder (not crystals) in a size “0” gelatin capsule. These are for vaginal use only and should never be taken by mouth.
Clothing and Hygiene Habits That Help
Yeast thrives in warm, moist environments, so anything that traps heat and moisture against the vulva creates favorable conditions for overgrowth. Wearing 100% cotton underwear makes a real difference because cotton wicks away sweat and moisture. Synthetic fabrics with a small cotton crotch panel don’t offer the same protection since the surrounding synthetic material still traps heat.
Change out of wet swimsuits and sweaty workout clothes as soon as possible. Sleep without underwear if you’re comfortable doing so, giving the area a chance to dry out overnight. Avoid douching, scented tampons, and fragranced soaps in the vaginal area. These products disrupt the natural balance of bacteria that keeps yeast in check.
Diet and Blood Sugar
There’s a real connection between sugar and yeast growth. Yeast feeds on sugar, and diets high in simple sugars, white flour, and refined carbohydrates can contribute to recurring infections. You don’t necessarily need to eliminate these foods entirely. Even modest reductions in sugar intake, combined with more protein, healthy fats, and low-starch vegetables, can reduce the frequency and severity of infections.
Uncontrolled diabetes is one of the strongest risk factors for chronic yeast infections because elevated blood glucose literally feeds the yeast. If you’re getting frequent infections and haven’t had your blood sugar checked recently, that’s worth discussing with your doctor. Getting glucose levels under control often resolves the pattern.
Antibiotics as a Trigger
Antibiotics are one of the most common triggers for yeast infections because they kill off the beneficial bacteria (especially lactobacillus species) that normally keep yeast populations low. If you notice a pattern of yeast infections following antibiotic courses, talk to your provider about using a preventive antifungal alongside the antibiotic. Some people also take oral probiotics during and after antibiotic treatment. The most studied probiotic strain for vaginal health is Lactobacillus rhamnosus GR-1, which has documented effects on reducing urogenital infections, though evidence for preventing yeast infections specifically is less definitive than for bacterial vaginosis.
Can a Sexual Partner Reinfect You?
Yeast infections aren’t classified as sexually transmitted infections, and routine partner treatment isn’t currently recommended for them. That said, yeast can be passed between partners during sex, and some people do notice a pattern of reinfection tied to sexual activity. If you’re dealing with recurrent infections and suspect reinfection, it’s reasonable to ask your provider whether treating your partner makes sense in your situation. Recent guidelines from ACOG now recommend partner treatment for recurrent bacterial vaginosis based on growing evidence that sexual transmission plays a role, but similar formal guidelines for yeast infections haven’t been established yet.
Using condoms during treatment and for a few days after can help prevent passing yeast back and forth. Avoid sex entirely while using vaginal suppositories or creams, as these products can weaken latex condoms and make intercourse uncomfortable on inflamed tissue.
How Long Until You Feel Better
With treatment, itching and burning typically start improving within one to two days. Full resolution, including discharge returning to normal, usually takes about a week for uncomplicated infections. Severe cases can take longer. If your symptoms haven’t improved after a full course of treatment, the infection may involve a yeast strain that’s resistant to standard antifungals, or it may not be a yeast infection at all. Bacterial vaginosis and some sexually transmitted infections can mimic yeast infection symptoms, so getting a proper diagnosis matters, especially if over-the-counter treatments aren’t working.
