Most uncomplicated yeast infections are treated with antifungal medicine, either an over-the-counter cream or suppository you insert vaginally, or a single prescription pill taken by mouth. For many people, a 3- to 7-day course of antifungal treatment clears the infection completely. The right choice depends on whether this is a one-time infection, a recurring problem, or one that hasn’t responded to standard treatments.
Over-the-Counter Antifungal Options
The most widely used OTC treatments contain miconazole, the active ingredient in the Monistat product line. These come in several formats: vaginal creams, suppositories, and prefilled applicators. The key difference between products is how many days of treatment they require, which corresponds to the concentration of medicine in each dose.
- 1-day treatment: A single high-dose ovule containing 1,200 mg of miconazole, or a prefilled applicator with tioconazole 6.5% ointment. Convenient, but the concentrated dose can cause more local irritation.
- 3-day treatment: Suppositories or applicators delivering 200 mg of miconazole per dose, or a 4% miconazole cream. A middle ground between speed and tolerability.
- 7-day treatment: A lower-concentration 2% miconazole cream used nightly for a full week. This is often recommended for mild infections or for people who are sensitive to higher doses.
Many of these products come as “combination packs” that include an external cream (2% miconazole) for relieving itching and irritation on the vulva while the internal treatment works. You can expect symptom improvement within the first few days, though finishing the full course matters even if you feel better sooner.
Clotrimazole is another common OTC antifungal, sold under brand names like Gyne-Lotrimin. It works the same way as miconazole and comes in similar cream and suppository formats.
Prescription Oral Treatment
The most common prescription option is fluconazole, an antifungal pill. For a straightforward yeast infection, the standard dose is a single 150 mg tablet taken once. That’s it. Many people prefer this route because it’s simpler than multi-day vaginal treatments, and it works from the inside out.
Symptom relief typically begins within a day or two, with the infection clearing fully over the course of a few days. If your symptoms haven’t improved after treatment, or if they come back within two months, that’s a sign you may need a different approach or a closer look at whether the infection is actually yeast.
Newer Non-Azole Prescription Medicine
A newer oral option called ibrexafungerp (brand name Brexafemme) was approved by the FDA for vaginal yeast infections. It works differently from fluconazole and other azole antifungals. Instead of targeting the fungal cell membrane, it disrupts a component of the fungal cell wall, which makes it useful when standard azole treatments haven’t worked.
The dosing is two tablets taken in the morning, then two more in the evening, all on the same day. It’s approved for adults and post-menarchal adolescents. Because it uses a completely different mechanism, it can be effective against yeast strains that have developed resistance to traditional antifungals.
Treatment for Recurring Yeast Infections
If you get three or more yeast infections in a single year, that’s classified as recurrent vulvovaginal candidiasis. It affects fewer than 5% of women, but it requires a different treatment strategy than a one-time infection.
The approach has two phases. First, a longer initial treatment to fully suppress the yeast: either 7 to 14 days of a topical antifungal, or three doses of oral fluconazole (150 mg) spaced every three days. The goal is to drive the infection into complete remission before moving to the second phase.
That second phase is maintenance therapy: a weekly dose of oral fluconazole for six months. This schedule is effective at keeping infections from coming back during treatment, though the infections can sometimes return once the maintenance period ends. If oral fluconazole isn’t an option for you, intermittent topical treatments can serve the same role.
Boric Acid for Resistant Infections
Boric acid vaginal suppositories are sometimes recommended for yeast infections that don’t respond to standard antifungals, particularly infections caused by non-albicans Candida species. These are used by inserting a capsule vaginally at bedtime.
Boric acid is not a first-line treatment and is typically used under the guidance of a healthcare provider. It should not be taken by mouth (it’s toxic if swallowed), and it’s not approved for use during pregnancy or in children. While using it, condoms, diaphragms, and spermicides may not work reliably, and tampons should be avoided. Sexual activity is best postponed until treatment is complete.
Making Sure It’s Actually a Yeast Infection
Before choosing a treatment, it’s worth confirming that what you’re dealing with is actually a yeast infection, because the most commonly confused condition, bacterial vaginosis, requires a completely different medicine (antibiotics, not antifungals).
Yeast infections produce thick, white, cottage cheese-like discharge, along with itching, burning, and sometimes pain during intercourse. Bacterial vaginosis, by contrast, causes thin, grayish discharge that’s heavier in volume and has a noticeable fishy odor, especially after a period or sex. BV can cause irritation but typically doesn’t cause pain. Using an antifungal for BV won’t help and may delay proper treatment.
If you’ve had a yeast infection before and recognize the symptoms clearly, treating with an OTC antifungal is reasonable. If it’s your first time, the symptoms are unusual, or OTC treatment doesn’t resolve things within a week, getting a proper diagnosis ensures you’re using the right medicine.
