Most vaginal yeast infections clear up within a few days to a week using antifungal medications available over the counter at any pharmacy. The standard options are vaginal creams, suppositories, or a single prescription pill, and choosing between them mostly comes down to how quickly you want relief and whether you prefer topical or oral treatment.
Over-the-Counter Antifungal Options
The most widely used OTC treatments are miconazole and clotrimazole, both available as vaginal creams or suppositories. These work by breaking down the structure of the fungus causing the infection. A third option, tioconazole, is sold as a single-dose treatment.
The main difference between products on the shelf is treatment length. Miconazole suppositories come in three formats: a one-time 1,200 mg dose, a 200 mg dose used for three days, or a 100 mg dose used for seven days. Miconazole cream follows a similar pattern, with a 4% concentration used for three days and a 2% concentration used for seven. Clotrimazole cream is available in 1% and 2% strengths with comparable timelines.
Shorter courses use a higher dose per application, so they’re not necessarily gentler. A one-day or three-day product doesn’t mean you’ll feel better faster than someone using a seven-day cream. Symptoms typically start improving within a day or two regardless of which duration you choose, though a seven-day course can be a better fit for more stubborn infections. All of these products are similarly effective, so the choice is largely about convenience.
The Prescription Pill
Fluconazole is an oral antifungal that treats yeast infections with a single 150 mg dose. You take one pill, and that’s it. For many people, this is the simplest option since it avoids the mess of vaginal creams and the inconvenience of inserting suppositories at bedtime.
You’ll need a prescription, which means either visiting your doctor or using a telehealth service. Fluconazole works through the bloodstream rather than being applied directly to the infection site, so it can take a bit longer to feel full relief compared to topical treatments. Most people still see significant improvement within a few days.
Boric Acid Suppositories
Boric acid vaginal suppositories are sometimes used for yeast infections that don’t respond well to standard antifungals, particularly infections caused by less common strains of yeast. They help restore the acid balance in the vagina and can relieve itching and burning.
A few important safety notes: boric acid is toxic if swallowed and should only ever be used vaginally. It’s not safe during pregnancy or breastfeeding. While using it, condoms, diaphragms, and spermicides may not work properly, and tampons should be avoided. It’s best used at bedtime. If you’re considering boric acid, it’s worth confirming with a provider that you’re actually dealing with a yeast infection rather than something else that needs different treatment.
Make Sure It’s Actually a Yeast Infection
This matters more than most people realize. Bacterial vaginosis (BV) is just as common as yeast infections, and the two require completely different treatments. Antifungal creams do nothing for BV.
Yeast infections typically produce thick, white, odorless discharge, often with a white coating in and around the vagina. The hallmark symptoms are itching and burning. BV, by contrast, tends to cause thin, grayish, foamy discharge with a noticeable fishy smell, though BV sometimes has no symptoms at all. If your discharge is off-color, has a strong odor, or your symptoms don’t match the classic yeast infection pattern, it’s worth getting tested rather than self-treating.
What to Use During Pregnancy
If you’re pregnant, stick with vaginal creams or suppositories like miconazole or clotrimazole. These are safe to use at any point during pregnancy and don’t cause birth defects or other complications.
Oral fluconazole is a different story. There’s a possible link between oral antifungals and miscarriage or birth defects, particularly during the first trimester. Health professionals recommend avoiding fluconazole and other prescription oral antifungals entirely during pregnancy.
When Infections Keep Coming Back
Recurrent yeast infections, defined as three or more episodes in a single year, affect fewer than 5% of women but can be genuinely disruptive. If you’re in this group, the standard one-and-done treatments aren’t enough.
The CDC-recommended approach for recurrent infections is a weekly dose of oral fluconazole taken for six months as a maintenance regimen. This suppressive therapy keeps yeast levels in check over time rather than just treating individual flare-ups. If oral medication isn’t an option, intermittent topical treatments can serve a similar purpose. Recurrent infections are worth discussing with a provider, since they sometimes signal an underlying factor like uncontrolled blood sugar or immune system changes.
Reducing Your Risk Going Forward
A few straightforward habits lower the odds of yeast infections returning. Wear cotton underwear and breathable clothing that isn’t too tight. Keeping the vaginal area clean and dry matters, especially after exercise or swimming. Avoid unnecessary antibiotics, since they kill off the beneficial bacteria that normally keep yeast in check. If antibiotics are prescribed for another condition, take them exactly as directed and for only as long as needed.
Scented soaps, douches, and vaginal sprays can disrupt the natural balance of organisms in the vagina, creating conditions that favor yeast overgrowth. Plain water or a mild, unscented cleanser on the external area is all that’s needed.
