Most yeast infections are treated with antifungal medications, either applied directly in the vagina as a cream or suppository, or taken as a single oral pill. Over-the-counter options work just as well as prescription treatments for straightforward infections, with cure rates around 85% regardless of whether you use a one-day or seven-day course.
Over-the-Counter Creams and Suppositories
The most accessible treatments are topical antifungals you can buy at any pharmacy without a prescription. These come as vaginal creams, suppositories, or combination packs and are sold under familiar brand names like Monistat and Gyne-Lotrimin. The active ingredients belong to a class of drugs called azoles, which kill the fungus by breaking down its cell membrane. The most common options are miconazole, clotrimazole, and tioconazole.
These products come in one-day, three-day, and seven-day courses. Clinical trials comparing single-dose vaginal treatments to multi-dose regimens found no statistical difference in cure rates, with about 85% of patients symptom-free within one to four weeks regardless of course length. The main practical difference is that shorter courses use a higher concentration of medication per dose, which can cause more local irritation in some people. If you’ve had a yeast infection before and recognize the symptoms, picking up a three-day or seven-day kit is a reasonable first step.
Prescription Oral Treatment
For people who prefer a pill over a topical treatment, a single dose of oral fluconazole is the standard prescription option. It’s convenient and effective for uncomplicated infections. Most people notice improvement within a day or two, though full symptom relief can take up to 72 hours.
Fluconazole isn’t appropriate for everyone. People with heart rhythm problems, liver disease, or kidney disease may need extra monitoring or a different treatment. It can also interact with a number of other medications. And it’s not safe during pregnancy: epidemiologic studies have linked even a single dose to an increased risk of spontaneous abortion and congenital anomalies. Pregnant people should use topical treatments only.
Treatment During Pregnancy
Yeast infections are common during pregnancy, and the treatment options narrow considerably. The CDC recommends only topical azole creams or suppositories, applied for a full seven days. Shorter courses are not recommended in pregnancy, and oral fluconazole should be avoided entirely. Miconazole and clotrimazole creams are the go-to choices, and both have long safety records for use during pregnancy.
When Infections Keep Coming Back
If you get four or more yeast infections in a year, that’s classified as recurrent vulvovaginal candidiasis. Simple one-and-done treatments usually aren’t enough. The standard approach involves an initial course of treatment to clear the active infection, followed by a maintenance phase of lower-dose antifungal medication taken regularly for several months to keep the fungus from rebounding.
A newer prescription option, ibrexafungerp (brand name Brexafemme), was FDA-approved specifically for vaginal yeast infections and works through a completely different mechanism than traditional azoles. Instead of targeting the fungal cell membrane, it disrupts the fungal cell wall. This distinction matters because it retains activity against most fluconazole-resistant Candida species, making it a useful option when standard treatments stop working. The treatment is a one-day course of two doses taken about 12 hours apart.
Boric acid vaginal suppositories (600 mg) are another option sometimes recommended for recurrent or resistant infections. They work primarily as a local treatment, with only about 6% of the dose being absorbed into the body. Boric acid is particularly useful against non-standard Candida species that don’t respond well to azole medications. These suppositories are available without a prescription at most pharmacies but should not be taken orally, as boric acid is toxic when swallowed.
Probiotics as an Add-On
Probiotics won’t replace antifungal treatment, but adding them alongside standard therapy may improve outcomes. A meta-analysis found that combining Lactobacillus-based probiotics with antifungals improved short-term cure rates by about 14% and cut one-month relapse rates by 66%. The strains with the most clinical data include L. acidophilus, L. rhamnosus, and L. rhamnosus combined with lactoferrin (a protein found naturally in breast milk and other secretions).
One small but well-designed trial tested a specific regimen for women with recurrent infections: standard antifungal treatment plus an oral probiotic during the active phase, then continued probiotic use during the premenstrual window each month. After six months, only 29% of the probiotic group had a recurrence, compared to 100% in the control group. The evidence is promising, though the studies so far have been small. Not every probiotic product is equally useful, and some tested strains (like L. plantarum) showed no benefit for vaginal symptoms.
Make Sure It’s Actually a Yeast Infection
Before treating, it helps to know what you’re dealing with. Yeast infections and bacterial vaginosis (BV) are the two most common causes of vaginal discomfort, and they require different treatments. The easiest way to tell them apart is by the discharge. Yeast infections typically produce thick, white, cottage cheese-like discharge with minimal odor. BV tends to cause thin, grayish discharge that’s heavier in volume and often has a fishy smell. Using antifungal medication for BV won’t help, and vice versa.
If your symptoms are new, unclear, or don’t improve after a full course of over-the-counter treatment, getting tested is worthwhile. A simple swab can confirm whether Candida is the cause or whether something else is going on.
Home Remedies to Avoid
The internet is full of suggestions for treating yeast infections with household items like garlic cloves or tea tree oil. These are not supported by reliable evidence and carry real risks. Garlic applied vaginally has caused second-degree burns in multiple documented cases. Tea tree oil is a potent irritant to mucosal tissue and can cause chemical burns or allergic reactions. Yogurt, coconut oil, and apple cider vinegar similarly lack clinical evidence and can disrupt vaginal pH, potentially making things worse. Stick with proven antifungal treatments.
