Most yeast infections clear up within a few days using antifungal creams or suppositories available at any pharmacy without a prescription. If you’re fairly sure you have a yeast infection (thick, white, odorless discharge plus itching, burning, or swelling around the vagina), an over-the-counter treatment is a reasonable first step. If it’s your first infection, symptoms don’t improve within a week, or you’re pregnant, getting a proper diagnosis first makes a real difference in how quickly you recover.
Over-the-Counter Antifungal Treatments
The two most common active ingredients in OTC yeast infection products are miconazole (sold as Monistat) and clotrimazole (sold as Lotrimin or Mycelex). Both come as vaginal creams, ointments, or suppositories, and both work by killing the fungus causing the infection. CDC treatment guidelines list them as equally effective first-line options for uncomplicated yeast infections.
You’ll see products labeled as 1-day, 3-day, or 7-day treatments. The number refers to how many days you insert the medication, not how quickly symptoms disappear. Single-dose miconazole suppositories have clinical cure rates around 74%, while 7-day miconazole courses have very low relapse rates (about 3.4%). Shorter treatments are more convenient, but longer courses tend to be more thorough. A 3-day or 7-day regimen is a solid choice if you want the best chance of clearing the infection completely on the first try.
There’s also tioconazole, a single-application ointment available without a prescription. It works the same way as the others. Whichever product you choose, use the full course even if symptoms improve early. Stopping partway through is one of the most common reasons infections come back.
Getting Relief While You Wait
Antifungal treatments typically take two to three days before you notice real improvement, and the itching and burning in the meantime can be miserable. Many OTC yeast infection kits include an external anti-itch cream meant for the vulva (the skin outside the vagina). These contain a small amount of antifungal or a mild steroid like hydrocortisone to reduce inflammation.
A cool compress or a lukewarm bath (no soap, no bubble bath) can also take the edge off. Avoid scratching, which can break the skin and make irritation worse. Loose clothing and cotton underwear reduce friction and let the area breathe while you’re healing.
When a Prescription Makes More Sense
For straightforward yeast infections, a single oral dose of fluconazole (150 mg) works as well as topical treatments and is more convenient for some people. It requires a prescription. Most people tolerate it well, though it can interact with a long list of other medications, particularly those that affect heart rhythm or liver function. If you take multiple prescriptions, mention them before starting fluconazole.
A prescription is also the better route if OTC treatments haven’t worked after a full course, if your symptoms are severe (significant swelling, cracks or sores on the skin, intense redness), or if you get four or more yeast infections in a single year. That threshold of four per year is what clinicians call recurrent vulvovaginal candidiasis, and it usually requires a longer treatment plan rather than repeated short courses.
Yeast Infection During Pregnancy
Yeast infections are more common during pregnancy because of hormonal shifts, and they’re safe to treat with topical antifungal creams or suppositories at any stage. Products containing miconazole or clotrimazole do not cause birth defects or pregnancy complications.
Oral antifungals are a different story. Fluconazole taken by mouth during pregnancy, especially in the first trimester, has a possible link to miscarriage and birth defects. Stick with vaginal creams or suppositories, and get a confirmed diagnosis before treating, since bacterial vaginosis and other conditions can mimic yeast infection symptoms.
Make Sure It’s Actually a Yeast Infection
About two-thirds of women who self-diagnose a yeast infection are wrong. That matters because using antifungal medication for bacterial vaginosis or another condition delays the right treatment and can make things worse. The differences are fairly straightforward to spot:
- Yeast infection: thick, white, odorless discharge (often described as cottage cheese-like), with itching, burning, and sometimes a white coating on the vaginal walls.
- Bacterial vaginosis: thin, grayish, foamy discharge with a noticeable fishy smell, especially after sex. Itching is less prominent.
If you’ve had yeast infections before and recognize the pattern, self-treating is reasonable. If there’s any doubt, a quick swab at a clinic gives a definitive answer.
Boric Acid for Stubborn Infections
When standard antifungal treatments fail, boric acid vaginal suppositories are sometimes recommended for resistant or recurrent infections. The typical regimen from UW Medicine is one capsule inserted vaginally each night for two weeks. Boric acid capsules are available over the counter, but this is a treatment to use under guidance from a healthcare provider, not as a first attempt. Boric acid is toxic if swallowed and should never be taken orally or used on broken skin.
Do Probiotics Help?
The idea that probiotics can prevent or treat yeast infections has some supporting evidence, but it’s not strong enough to rely on. A Cochrane review of five clinical trials found that adding probiotics (various Lactobacillus and Bifidobacterium strains) to standard antifungal treatment improved short-term cure rates. A smaller trial found that combining antifungal therapy with oral probiotics containing L. acidophilus and L. rhamnosus reduced recurrent itching and discharge. But another trial using a different Lactobacillus strain showed no improvement at all.
The takeaway: probiotics might offer a modest boost alongside antifungal treatment, particularly for recurrent infections, but they aren’t a replacement for antifungals. If you want to try them, look for products containing L. rhamnosus or L. acidophilus, and use them as an addition to your treatment rather than a substitute.
Preventing Future Infections
Some yeast infections happen for no identifiable reason, but a few habits consistently reduce your risk. The CDC recommends wearing cotton underwear, choosing breathable (not too tight) clothing, and keeping the vaginal area clean and dry. Change out of wet swimsuits and sweaty workout clothes promptly. When washing, plain water or a mild, unscented soap on the external area is sufficient. Douching disrupts your natural vaginal bacteria and increases infection risk.
Antibiotics are one of the most common triggers for yeast infections because they kill off protective bacteria along with the ones causing illness. If you’re prone to yeast infections after antibiotic courses, let your prescriber know. They may recommend a preventive dose of antifungal medication alongside the antibiotics. High blood sugar also feeds yeast growth, so people with diabetes who have frequent infections may see improvement with tighter glucose management.
