Vaginal thrush is treated with antifungal medication, either as a cream or pessary inserted vaginally or as a single oral capsule. Most uncomplicated infections clear within a few days of starting treatment, and many options are available over the counter without a prescription. The right choice depends on whether this is your first episode, how severe your symptoms are, and whether you’re pregnant.
Over-the-Counter Topical Treatments
Antifungal creams and pessaries (small dissolvable tablets inserted into the vagina) are the most common first step. Clotrimazole is the go-to active ingredient, available in 1-day, 3-day, or 6-day courses depending on the strength. You insert the pessary at bedtime using an applicator, and an external cream can be applied to the vulva to relieve itching and soreness in the meantime. Miconazole is another widely available option that works the same way.
These topical treatments work directly at the site of infection, which means side effects are minimal. Occasional mild burning or irritation at the application site is the most common complaint. Oil-based creams and pessaries can weaken latex condoms and diaphragms, so avoid relying on these for contraception during treatment and for a few days afterward.
Oral Antifungal Treatment
A single-dose oral capsule containing fluconazole is the main alternative to topical treatment. You take one 150 mg capsule, and for most women symptoms start improving within 24 hours and resolve fully within a few days. It’s convenient and equally effective as topical options for straightforward infections.
Fluconazole does carry some contraindications. It should not be used during pregnancy. Studies have linked even a single 150 mg dose to an increased risk of miscarriage and birth defects. It can also interact with certain medications, so if you take anything regularly, check with a pharmacist before buying it.
Treatment During Pregnancy
If you’re pregnant, only topical antifungal treatments are recommended, applied for a full 7-day course. Oral fluconazole is off the table entirely. Thrush is more common during pregnancy due to hormonal changes that shift the vaginal environment, so a longer course helps ensure the infection fully clears. Talk to your midwife or doctor before starting treatment so they can confirm it’s thrush rather than another type of infection.
How to Tell It’s Actually Thrush
Before you self-treat, it’s worth making sure you’re dealing with thrush and not something else. Bacterial vaginosis (BV) is the most commonly confused condition, and treating BV with antifungal cream won’t help.
The key differences come down to discharge and smell. Thrush produces thick, white discharge with a cottage-cheese texture and typically no strong odor. BV causes thin, grayish or yellowish discharge with a noticeable fishy smell. If your symptoms don’t match the classic thrush pattern, or if you’ve never had thrush before and aren’t sure what you’re dealing with, it’s worth getting a proper diagnosis rather than guessing.
When Self-Treatment Isn’t Appropriate
Over-the-counter treatment is reasonable if you’ve had thrush before, recognize the symptoms, and are otherwise healthy. But there are situations where you should see a doctor instead:
- You’ve had several episodes in a short period. Four or more episodes in a year counts as recurrent thrush, which needs a different treatment approach.
- You’ve had a new sexual partner recently. Similar symptoms can be caused by sexually transmitted infections that need different treatment.
- You have pelvic pain, abnormal bleeding, sores, or colored discharge. These suggest something other than a simple yeast infection.
- You tried an over-the-counter treatment and it didn’t work. The infection may involve a resistant strain or may not be thrush at all.
Dealing With Recurrent Thrush
If thrush keeps coming back (four or more times a year), a single treatment course won’t solve the underlying pattern. Recurrent thrush typically requires an extended suppressive regimen: an initial intensive treatment phase followed by a lower-dose antifungal taken regularly for several months to keep the yeast from rebounding. Your doctor will tailor this based on your history and may take a swab to identify the specific yeast species involved.
This matters because not all yeast responds to the same drugs. About 6% of Candida infections are resistant to fluconazole, the most commonly used oral antifungal. Fluconazole resistance is a growing concern in vaginal yeast infections specifically, so if standard treatment keeps failing, a swab culture can guide your doctor toward an antifungal that will actually work.
Do Probiotics Help?
Probiotics have become a popular add-on, and there is some evidence behind them, though it’s nuanced. A large meta-analysis published in the American Journal of Obstetrics and Gynecology found that taking probiotics alongside standard antifungal treatment improved short-term cure rates (within a month) and reduced the chance of recurrence at six months. For women with recurrent thrush, the combination roughly tripled the three-month cure rate compared to antifungals alone.
Probiotics on their own, however, are not a substitute for antifungal medication. When tested head-to-head against antifungals, probiotics alone produced lower long-term cure rates. Think of them as a useful supplement to standard treatment, particularly if you’re prone to recurrence, not a replacement for it.
Lifestyle Changes That Support Recovery
Yeast thrives in warm, moist environments, so small changes to your daily routine can help during treatment and reduce the chance of another episode. Wear cotton underwear and avoid tight-fitting clothing that traps heat and moisture. Keep the vulval area clean and dry, but skip scented soaps, bubble baths, and vaginal deodorants, all of which can disrupt the natural balance of bacteria and yeast.
After swimming or exercising, change out of damp clothing promptly. Avoid douching, which washes away the protective bacteria that normally keep yeast in check. These measures won’t cure an active infection on their own, but they create an environment that’s less hospitable to yeast overgrowth and more supportive of the treatment you’re using.
Does Your Partner Need Treatment?
Thrush isn’t classified as a sexually transmitted infection, and routine treatment of male sexual partners isn’t typically recommended. Most men exposed to vaginal yeast won’t develop symptoms. However, if your partner has signs of a yeast infection (redness, irritation, or itching on the penis), they should be treated with an antifungal cream. Reinfection from an untreated symptomatic partner is possible, though it’s not the most common reason thrush comes back.
