Most yeast infections are treated with antifungal medications available over the counter as vaginal creams, ointments, or suppositories. For simple, uncomplicated infections, these topical treatments work well and clear symptoms within a few days. A single-dose prescription pill is also widely used. The right choice depends on how severe your infection is, whether it keeps coming back, and whether you’re pregnant.
Over-the-Counter Treatments
The two most common OTC options are clotrimazole (sold as Mycelex and Lotrimin AF) and miconazole (sold as Monistat). Both belong to a class of drugs called azoles, which kill yeast by disrupting a key component of the fungal cell membrane. Without that membrane intact, the yeast cell leaks nutrients and dies. These medications come in several treatment lengths: one-day, three-day, and seven-day courses. Shorter courses use a higher concentration of the drug in each dose, so they aren’t necessarily faster-acting. Many people find the seven-day option causes less local irritation.
Tioconazole is a third OTC option, available as a single-dose vaginal ointment. All three medications treat the same type of infection and have similar cure rates. Choosing between them is largely a matter of preference for the format (cream vs. suppository vs. ointment) and how many days you want to use the product.
Common Side Effects of Topical Treatments
The most frequent side effect of vaginal antifungals is temporary burning, itching, or irritation at the application site. This can feel counterintuitive since itching is the symptom you’re trying to fix, but mild irritation from the medication itself usually fades within a day or two. Stop using the product and contact a healthcare provider if you develop a rash, hives, stomach pain, fever, chills, nausea, or foul-smelling discharge. These symptoms can signal an allergic reaction or a different type of infection altogether.
Prescription Oral Medication
Fluconazole, commonly known by the brand name Diflucan, is the standard prescription alternative. For a straightforward yeast infection, the typical dose is a single 150 mg pill taken by mouth. Many people prefer this route because it’s one dose and done, with no creams or suppositories involved. It works through the same basic mechanism as the topical azoles, targeting ergosterol production in the fungal cell membrane, but it reaches the infection through the bloodstream instead of direct application.
Fluconazole can cause headache, nausea, or abdominal discomfort in some people. It also interacts with a number of other medications, so your provider will want to know what else you’re taking before prescribing it.
Treatment for Recurrent Infections
Recurrent yeast infections are defined as three or more symptomatic episodes within a single year. This affects fewer than 5% of women but can be frustrating and disruptive. The standard maintenance approach is oral fluconazole taken once weekly for six months. This prolonged course suppresses the yeast long enough to break the cycle of reinfection for most people.
Recurrent infections are also more likely to involve less common yeast species that don’t respond as well to standard treatments. The most notable is Candida glabrata, which can be resistant to fluconazole. For these cases, providers often turn to terconazole, a prescription vaginal suppository that has shown effectiveness against both C. glabrata and other atypical species in clinical trials.
Boric Acid for Resistant Cases
When standard antifungals fail, boric acid vaginal suppositories are a well-established second-line option, particularly for infections caused by atypical yeast species like C. glabrata or C. tropicalis. The typical protocol, as outlined by UW Medicine, is one capsule inserted vaginally each night for two weeks. You can purchase pre-made suppositories or fill size “0” gelatin capsules with boric acid powder (not crystals) yourself.
One critical safety point: boric acid is highly toxic if swallowed. It is only used as a vaginal insert, never taken by mouth, and must be kept away from children. When used vaginally as directed, it is not toxic to vaginal tissue.
Medication Safety During Pregnancy
If you’re pregnant, topical antifungals like clotrimazole and miconazole are the recommended treatment. These creams and suppositories can be used at any point during pregnancy and do not cause birth defects or pregnancy complications. Oral fluconazole, on the other hand, should be avoided during pregnancy, especially in the first trimester. Research has raised concerns about a possible link between oral antifungal use and miscarriage or birth defects, which is why healthcare providers steer pregnant patients toward topical options instead.
Making Sure It’s Actually a Yeast Infection
Before choosing a medication, it helps to confirm you’re treating the right condition. Yeast infections, bacterial vaginosis, and trichomoniasis can all cause vaginal discomfort, but they require completely different treatments. Using antifungal medication for bacterial vaginosis won’t help and delays appropriate care.
The discharge patterns are the easiest way to tell them apart. Yeast infections produce thick, white, odorless discharge, sometimes with a white coating in and around the vagina. Bacterial vaginosis causes grayish, foamy discharge with a fishy smell. Trichomoniasis typically produces frothy, yellow-green discharge that smells bad and may contain spots of blood. If your symptoms don’t match the classic yeast infection pattern, or if OTC treatment doesn’t resolve things within a week, getting tested is the most reliable next step.
