Vulvovaginal candidiasis is commonly treated with topical azoles or a single oral fluconazole dose. Systemic contributors (antibiotics, high blood sugar, immune status) influence recurrence. Probiotics and diet may help as adjuncts but are not proven cures. Seek medical evaluation for recurrent, severe, or pregnancy-associated infections.

What causes a yeast infection?

Vulvovaginal candidiasis (often called a yeast infection) is most commonly caused by the fungus Candida albicans, a normal part of the vaginal and gut microbiota. Growth can overtake natural balance when local conditions change - for example after antibiotics, high blood sugar, pregnancy, or immune suppression.

Conventional (prescription and OTC) treatments

Topical azole antifungals (clotrimazole, miconazole, tioconazole) remain first-line for uncomplicated vaginal yeast infections and are widely available over the counter. A single oral dose of fluconazole (commonly 150 mg) is also frequently used for nonpregnant people and can be effective when appropriate.

For superficial mucocutaneous infections, nystatin is an option. Amphotericin B is an antifungal used for invasive (systemic) candidiasis in hospitalized or immunocompromised patients and is not a routine treatment for vaginal yeast infections.

If symptoms persist or recur, see a clinician. Recurrent vulvovaginal candidiasis (commonly defined as four or more episodes a year) may require longer antifungal maintenance regimens and evaluation for underlying contributors such as diabetes, immunosuppression, or medication exposures.

Natural and supportive approaches

Addressing systemic contributors can reduce recurrence. General measures include managing blood glucose, reviewing recent antibiotic or steroid use, and optimizing immune health through sleep, stress reduction, and balanced nutrition.

Some dietary changes are commonly recommended (reducing refined sugar, limiting excessive alcohol, prioritizing vegetables and fiber) because they support overall gut and metabolic health. High-quality evidence that specific diets cure or reliably prevent vaginal candidiasis is limited.

Fermented dairy with live cultures (plain yogurt containing Lactobacillus) and certain probiotic strains have shown modest benefits in some trials as an adjunct to antifungal therapy, but results vary. Probiotics are not a standalone, proven cure for symptomatic infections. 1

Herbal remedies such as tea tree oil, garlic, or plant extracts have been used historically; evidence is inconsistent, and topical use can cause irritation or allergic reactions. Avoid inserting undiluted essential oils or unapproved home preparations into the vagina.

Practical recommendations

  • For a first or uncomplicated infection: consider a single-dose oral fluconazole (if not pregnant and cleared by a clinician) or a short course of topical azole per package instructions.
  • For recurrent or severe symptoms, pregnancy, diabetes, or immunosuppression: see a healthcare provider for diagnosis and tailored treatment.
  • Use probiotics or dietary changes as supportive measures, not as a substitute for antifungal therapy.
When in doubt, consult a clinician - accurate diagnosis (to distinguish candidiasis from other causes of vaginal discharge) guides safe and effective treatment.

FAQs about Yeast Infection Medicine

What are first-line medicines for a yeast infection?
Topical azole antifungals (clotrimazole, miconazole, tioconazole) are first-line for uncomplicated infections. A single oral dose of fluconazole is commonly used in nonpregnant people.
Can probiotics or yogurt cure a yeast infection?
Probiotics and live-culture yogurt may help as adjuncts and support microbiome balance, but evidence is mixed and they are not a reliable stand-alone cure.
When should I see a healthcare provider?
See a clinician if you have severe symptoms, recurrent infections (commonly defined as four or more episodes a year), pregnancy, diabetes, or if over-the-counter treatments don't work.
Are diet changes effective against Candida?
Healthy dietary changes that support metabolic and gut health (reducing refined sugars, increasing vegetables and fiber) can be supportive, but there's limited high-quality evidence that specific diets reliably treat or prevent vaginal candidiasis.
Is amphotericin B used for vaginal yeast infections?
No. Amphotericin B treats invasive systemic candidiasis in hospitalized or immunocompromised patients and is not a routine treatment for typical vaginal yeast infections.
