A yeast infection is treated with antifungal medicine that clears the overgrown Candida. For a simple case, you can use an over-the-counter intravaginal azole cream over several days or take a single oral fluconazole pill by prescription. Both work well; recurrent infections need a longer course followed by months of weekly maintenance therapy.

What causes a yeast infection and why it usually isn't an STI
A vaginal yeast infection is a fungal overgrowth, almost always of Candida albicans, a yeast that normally lives in small numbers in the vagina and gut. When the balance shifts — after antibiotics wipe out protective bacteria, during pregnancy, with uncontrolled diabetes, or under hormonal changes — the yeast multiplies and inflames the vaginal walls and vulva. It's one of the most common fungal infections, and it is not usually acquired through sex, so it isn't classed as a sexually transmitted infection CDC. That distinction matters because it shapes who needs treatment and whether your partner does.
The hallmark is thick, white, odorless discharge often compared to cottage cheese, with intense itching and soreness. If you're not sure that's what you have, it's worth checking the full list of yeast infection symptoms and reviewing how it differs from a bladder infection in our breakdown of yeast infection vs uti before you self-treat.
How a yeast infection is treated: OTC vs prescription
For an uncomplicated infection in an otherwise healthy person, you have two equally effective routes — a topical azole you insert vaginally, or a single oral pill CDC STI Tx Guidelines, 2021:
- Intravaginal azoles (over-the-counter): clotrimazole 1% cream used for 7–14 days, or miconazole 2% cream used for 7 days. These come as creams, suppositories, or combination packs and you can buy them without a prescription.
- Oral fluconazole (prescription): a single 150 mg dose by mouth. One pill, one time — convenient, but you need a clinician to prescribe it.
- Recurrent or complicated cases: a longer initial course to clear the infection, then maintenance, such as weekly oral fluconazole for 6 months to keep it from coming back.
Neither route is clearly superior for a one-off infection — it comes down to preference. Some people want the convenience of a single pill; others prefer to avoid an oral medication or want to start treating the same hour they buy it. Both clear most uncomplicated infections.
| Option | What it is | How you take it | Best for |
|---|---|---|---|
| Clotrimazole 1% cream | OTC intravaginal azole | Daily for 7–14 days | Anyone wanting an OTC, topical option |
| Miconazole 2% cream | OTC intravaginal azole | Daily for 7 days | Same — widely available off the shelf |
| Fluconazole 150 mg | Prescription oral pill | One dose, by mouth | People who prefer a single pill over a cream |
| Weekly fluconazole maintenance | Prescription regimen | Induction course, then weekly for 6 months | Recurrent infections (3+ episodes a year) |
When boric acid comes in
If symptoms keep returning despite fluconazole, the culprit may be a non-albicans strain of Candida that naturally resists the usual azoles RVVC review. These stubborn cases are where a clinician may add intravaginal boric acid capsules as a second-line option. Boric acid is for vaginal use only and is not something to start on your own — it's prescribed after testing identifies a resistant strain.
What treatment is actually like
Whichever route you choose, it's a defined course — and the most common mistake is stopping early. The itching often eases within a day or two, but the antifungal still has work to do, so finish the full cream regimen or take the pill exactly as prescribed. With creams, expect some mild local irritation as you start; many people use the applicators at bedtime so the medicine stays in place. With the oral pill, relief is usually gradual over a couple of days rather than instant.
If you're buying OTC and you've never been diagnosed with a yeast infection before, get a clinician to confirm it first. Self-treating something that turns out to be bacterial vaginosis or trichomoniasis means days of the wrong medicine and a delayed real diagnosis. Testing is simple — a urine cup, a self-collected swab, or a quick exam, with results usually back in a few days, and it's free or low-cost at health departments, Planned Parenthood, and Title X clinics. You can get tested to rule out the look-alikes, and compare testing providers if you'd rather use an at-home option.
Does your partner need treatment?
Because a yeast infection isn't sexually transmitted, routine treatment of partners isn't recommended. A male partner doesn't usually need an antifungal unless he develops his own symptoms — most commonly an itchy, irritated rash on the head of the penis (balanitis), which can be treated topically. For people with recurrent infections, it's still reasonable to ask your clinician whether a partner's symptoms could be feeding a ping-pong cycle, but for a single episode, you don't have to treat anyone else.
Follow-up and when to retest
For a typical, uncomplicated infection that clears with treatment, no test-of-cure is needed — if your symptoms resolve, you're done. Come back if symptoms don't improve within a few days of finishing treatment, return shortly after, or never fully clear. Persistent or returning symptoms after a full course is the signal that something else is going on: a misdiagnosis, a resistant strain, or an underlying factor like diabetes. That's when a clinician will culture a sample to identify the exact species before changing the plan.
If your symptoms followed a new sexual partner, it's smart to confirm you're not dealing with an STI that mimics yeast. Trichomoniasis in particular causes discharge and irritation and is sexually transmitted. Knowing when to test after exposure helps you time that check so the result is reliable.
What happens if a yeast infection goes untreated
A yeast infection is generally mild and not dangerous, even when it recurs. Left alone, a mild case can sometimes settle on its own as the vaginal balance recovers, but more often the itching, burning, and soreness persist and worsen, and scratching can break the skin and invite a secondary bacterial infection. The bigger risk of skipping treatment is misjudging what you have — assuming it's yeast when it's bacterial vaginosis or trichomoniasis means leaving a treatable (and, with trich, transmissible) condition to linger. Recurrent infections — three or more symptomatic episodes in under a year — affect under 5% of women and, while uncomfortable, aren't a sign of serious disease.
Preventing the next one
You can't fully prevent yeast infections, but a few habits lower the odds CDC:
- Wear cotton underwear and breathable, not-too-tight clothing so the area stays dry rather than warm and damp.
- Keep the genital area clean and dry, and change out of wet swimwear or sweaty workout clothes promptly.
- Skip douches and scented washes, which disrupt the bacterial balance that keeps yeast in check.
- After antibiotics or during a known trigger like pregnancy, watch for early symptoms so you can treat fast.
- If the sexually transmitted look-alikes are a concern, using condoms every time lowers risk, and routine testing catches infections that have no symptoms.
When to see a clinician
See a clinician if it's your first suspected yeast infection, if symptoms don't clear after a full OTC course, if you're pregnant, if you have diabetes or a weakened immune system, or if you're getting them repeatedly. A diagnosis here is common and entirely treatable — clinics handle it daily, and it says nothing about you as a person. Getting the right name on what you have is what makes the treatment work the first time.
