Most yeast infections are treated with antifungal medications, either applied directly in the vagina or taken as a pill. For a straightforward, first-time infection, an over-the-counter cream or suppository will clear it up within a few days to a week. More severe or recurring infections typically require a prescription.
Over-the-Counter Treatments
Three antifungal ingredients are widely available without a prescription: miconazole, clotrimazole, and tioconazole. All three work by disrupting the cell walls of the yeast, killing the fungus directly at the site of infection. They come as vaginal creams, ointments, or suppositories that you insert using an included applicator.
Miconazole (sold as Monistat) is the most recognizable option. It comes in three formats: a single-dose treatment, a three-night course, or a seven-night course. Clotrimazole (sold as Trivagizole) is similar and available in three-day or seven-day versions. Tioconazole (sold as Vagistat) is a one-time ointment you apply once and you’re done.
Short courses of one to three days are effective for uncomplicated yeast infections. The seven-day formulas aren’t necessarily for worse infections. They use a lower concentration of medication spread over more days, which can mean less local irritation. If you’ve never been treated for a yeast infection before or aren’t sure that’s what you’re dealing with, it’s worth getting a diagnosis before self-treating, since bacterial vaginosis and other conditions can cause similar symptoms but need different medication entirely.
Prescription Oral Medication
Fluconazole (Diflucan) is the standard prescription option. It’s a single pill, taken once, at a 150 mg dose. For many people, this is the most convenient route: no applicators, no nightly routine, just one tablet. It works systemically, traveling through the bloodstream to reach the infection.
For severe infections with significant swelling, redness, or cracking of the skin, a single dose often isn’t enough. CDC guidelines recommend two doses taken 72 hours apart in those cases. Some providers prescribe two to three oral doses instead of vaginal therapy when symptoms are particularly uncomfortable, since oral treatment avoids applying anything to already-irritated tissue.
Common side effects of oral antifungals include stomach pain, nausea, and diarrhea. Topical treatments can cause local burning or itching, which is usually mild. Serious reactions like liver damage or severe allergic responses are rare with either form.
Treatment During Pregnancy
If you’re pregnant, topical antifungal creams and suppositories are the safe choice. Miconazole and clotrimazole don’t cause birth defects or pregnancy complications and can be used at any stage. A seven-day formula is recommended over shorter courses for the best results during pregnancy.
Oral fluconazole is a different story. There’s a possible link between oral antifungal pills and miscarriage or birth defects, particularly in the first trimester. The same applies to newer oral options like ibrexafungerp (Brexafemme), which is specifically contraindicated in pregnancy based on animal studies. If you’re pregnant or think you might be, stick with the topical treatments.
When Infections Keep Coming Back
Recurrent yeast infections, defined as four or more episodes in a year, need a longer strategy. The initial step is a more extended treatment course: either 7 to 14 days of a topical antifungal, or three oral doses of fluconazole spread over a week (taken on days one, four, and seven). The goal is to fully clear the yeast before starting maintenance therapy.
Once the active infection is gone, the maintenance phase involves taking a weekly oral dose of fluconazole for six months. This keeps yeast levels suppressed and prevents flare-ups. It’s effective at controlling recurrences, but it’s rarely a permanent cure. Some people experience infections again after stopping maintenance therapy.
A newer prescription option for recurrent infections is ibrexafungerp (Brexafemme), which works through a completely different mechanism than traditional antifungals. It’s FDA-approved both for treating individual episodes and for reducing recurrences when taken once monthly for six months. Because it belongs to a different drug class, it may be useful for people who haven’t responded well to the standard azole medications. It cannot be used during pregnancy, and a pregnancy test is recommended before each monthly dose.
Infections Caused by Resistant or Unusual Yeast Strains
Most vaginal yeast infections are caused by Candida albicans, and most strains respond well to standard antifungals. Resistance rates to common treatments sit around 4 to 5%, so the vast majority of infections will clear with the medications described above.
Non-albicans strains, however, are trickier. These species are naturally less susceptible to fluconazole, so treatment guidelines call for a longer course (7 to 14 days) of a different topical antifungal. If the infection returns after that, boric acid capsules inserted vaginally once daily for three weeks are an established alternative, with clearance rates of about 70%. Boric acid is not something you’d take orally; it’s used strictly as a vaginal suppository and is typically compounded by a pharmacy.
If you’ve been treated multiple times and your symptoms keep returning or never fully resolve, the type of yeast involved matters. A culture can identify the specific species and guide your provider toward the right medication rather than repeating treatments that aren’t working.
Choosing Between Topical and Oral Treatment
For a simple yeast infection, topical and oral treatments have comparable effectiveness. The choice often comes down to personal preference. Topical creams and suppositories work locally with minimal whole-body side effects, but they require nightly application and can be messy. A single fluconazole pill is more convenient but carries a small risk of stomach upset and isn’t an option during pregnancy.
If your symptoms are severe, with significant swelling, raw skin, or fissures, a longer treatment course in either form will produce better results than a quick one-day or three-day option. Short courses are designed for mild, uncomplicated infections. Matching the treatment length to the severity of your symptoms is more important than choosing between cream and pill.
