Most uncomplicated yeast infections can be treated with over-the-counter antifungal creams or suppositories, or with a single dose of a prescription oral pill. The right choice depends on how severe your symptoms are, whether you’re pregnant, and how often these infections come back.
Over-the-Counter Antifungal Treatments
The most common first step is an OTC vaginal antifungal, available at any pharmacy without a prescription. These products contain one of a few active ingredients: miconazole (sold as Monistat), tioconazole (sold as Vagistat), or clotrimazole. They come as creams you apply with an applicator or as vaginal suppositories, and they all work by breaking down the cell walls of the yeast causing your infection.
You’ll see them labeled by treatment length: 1-day, 3-day, or 7-day courses. The shorter courses use a higher concentration of medication in each dose, while the 7-day versions spread a lower concentration across more days. The total amount of antifungal you receive is similar across all three. Many people prefer the shorter options for convenience, but the 7-day treatment tends to cause less local irritation and is the standard recommendation during pregnancy.
Most of these products also include an external cream for the vulvar itching and burning that often accompanies a yeast infection. You can use this cream for symptom relief even while the internal treatment is working. Symptoms generally start improving within a day or two, though you should finish the full course regardless.
Prescription Oral Medication
If you’d rather skip the creams, the main prescription alternative is a single 150-mg oral antifungal pill (fluconazole, commonly known by the brand name Diflucan). It works systemically, meaning you swallow it and the medication reaches vaginal tissue through your bloodstream. For a straightforward yeast infection, one dose is the entire treatment.
Many people prefer this option because it’s simple and avoids the messiness of vaginal creams. The tradeoff is that you need a prescription, and some people experience mild side effects like headache, nausea, or stomach discomfort. It also takes a bit longer to feel relief compared to topical treatments, typically 24 to 72 hours.
For more severe infections, where you have significant redness, swelling, or cracking of the skin, a single dose may not be enough. In those cases, a provider may prescribe a second dose taken 72 hours after the first.
What to Take During Pregnancy
Pregnancy narrows your options significantly. The CDC recommends only topical antifungal creams or suppositories applied for a full 7 days. The oral pill (fluconazole) is not recommended during pregnancy because epidemiologic studies have linked even a single 150-mg dose to an increased risk of spontaneous abortion and congenital anomalies. If you’re pregnant and dealing with a yeast infection, stick with a 7-day vaginal cream like miconazole or clotrimazole.
Treatment for Recurrent Infections
If you’re getting four or more yeast infections in a single year, the standard one-and-done treatments won’t solve the underlying pattern. Recurrent infections often require an initial treatment to clear the current episode followed by a maintenance regimen, typically a lower dose of oral fluconazole taken weekly for six months, to keep the yeast from bouncing back.
Boric acid vaginal suppositories are another option specifically useful for recurrent infections or infections caused by less common yeast species that don’t respond well to standard antifungals. According to UW Medicine guidelines, the typical protocol is one capsule inserted vaginally each night for two weeks to treat an active infection. After that, a maintenance schedule of two nights per week for 6 to 12 months can help prevent recurrence. These capsules are made with boric acid powder (not crystals) packed into size “0” gelatin capsules. Boric acid is toxic if swallowed, so these are strictly for vaginal use.
Make Sure It’s Actually a Yeast Infection
Before you treat, it’s worth confirming what you’re dealing with. Yeast infections and bacterial vaginosis (BV) are the two most common vaginal infections, and they require completely different treatments. Antifungals do nothing for BV, and BV antibiotics do nothing for yeast.
The differences are fairly distinct. A yeast infection produces thick, white, cottage cheese-like discharge and usually doesn’t have a noticeable odor. Itching is the hallmark symptom, sometimes accompanied by burning during urination. BV, on the other hand, produces thin, gray or yellowish discharge with a strong fishy odor and generally doesn’t cause itching or burning.
If you’ve had yeast infections before and recognize the symptoms clearly, treating with an OTC antifungal is reasonable. But if this is your first infection, your symptoms don’t match the typical pattern, or your symptoms don’t improve after a full course of treatment, getting a proper diagnosis through a vaginal swab is the more reliable path. Treating the wrong infection delays relief and can make things worse.
