Most vaginal yeast infections clear up within a few days using antifungal treatments available at any pharmacy without a prescription. For a straightforward infection, you can pick up a cream or suppository, use it as directed for one to seven days, and expect relief to start within 24 to 48 hours. If it’s your first infection, if symptoms are severe, or if over-the-counter options aren’t working, a single prescription pill can handle it instead.
Over-the-Counter Treatments
The most common way to treat a yeast infection is with an antifungal cream or suppository inserted into the vagina. These come in three main formats: a one-day treatment, a three-day treatment, or a seven-day treatment. All use the same class of antifungal medication and have similar cure rates. The difference is concentration. A one-day option packs a higher dose into a single application, while the seven-day version spreads a lower dose across a full week.
The active ingredients you’ll see on the box are miconazole (sold as Monistat), clotrimazole, and tioconazole. Tioconazole is typically the one-day ointment. Clotrimazole is commonly sold as a three-day regimen. Miconazole comes in one-, three-, and seven-day versions. Most products also include an external cream for the vulva to help with itching and irritation while the internal treatment works.
If you’ve had a yeast infection before and recognize the symptoms, starting an OTC treatment right away is reasonable. Finish the full course even if symptoms improve after a day or two. Stopping early increases the chance the infection comes back.
Prescription Options
The prescription alternative is a single oral dose of fluconazole, a 150-milligram pill taken once. It’s convenient, effective, and works from the inside out. Symptoms usually start improving within a day, though full resolution can take two to three days. Some people prefer it because there’s no mess from creams or suppositories.
A prescription is also the better route if your symptoms are more intense, such as significant swelling, redness, or cracking of the skin around the vulva. For these more complicated infections, a provider may prescribe a longer course of fluconazole or a higher-strength topical treatment.
Make Sure It’s Actually a Yeast Infection
About two-thirds of women who self-diagnose a yeast infection are wrong. That matters because the wrong treatment won’t help and can delay relief. Yeast infections, bacterial vaginosis, and trichomoniasis all cause irritation, but their discharge is noticeably different.
- Yeast infection: thick, white, odorless discharge, often described as cottage cheese-like, with a white coating in and around the vagina.
- Bacterial vaginosis: grayish, foamy discharge with a fishy smell.
- Trichomoniasis: frothy, yellow-green discharge that smells bad and may have spots of blood.
If you’re not sure, or if this is your first time experiencing these symptoms, getting tested is worth it. A provider can confirm the diagnosis with a simple swab in minutes.
Recurrent Yeast Infections
If you’re getting four or more yeast infections in a single year, that’s classified as recurrent vulvovaginal candidiasis, and the approach changes. Occasional infections respond well to short courses of treatment. Recurrent ones typically need a longer suppressive strategy, often involving weekly oral fluconazole for six months after the initial infection clears.
Recurrent infections can also signal that a less common yeast strain is involved, one that doesn’t respond well to standard antifungals. Boric acid vaginal suppositories are sometimes recommended in these cases. They’re used at bedtime and are generally reserved for infections that haven’t responded to first-line treatments. Boric acid is not safe to take by mouth and should only be used vaginally.
Treatment During Pregnancy
Yeast infections are more common during pregnancy due to hormonal shifts, but treatment options are more limited. Only topical antifungal creams and suppositories are recommended, applied for a full seven days regardless of the product’s labeled duration. The oral pill, fluconazole, is not considered safe during pregnancy. Even a single dose has been associated with an increased risk of miscarriage and birth defects in epidemiologic studies.
Treatment for Men
Penile yeast infections (balanitis) are less common but do happen, particularly in uncircumcised men or those with diabetes. Treatment is simpler: a topical antifungal cream applied directly to the affected area. Miconazole, clotrimazole, and nystatin are the standard options. The infection typically clears within one to three weeks after starting treatment. If it persists beyond two weeks, a stronger prescription may be needed.
Habits That Help Prevent Recurrence
Yeast thrives in warm, moist environments. A few simple changes reduce the conditions it needs to grow. Wear cotton underwear and avoid tight-fitting clothing that traps heat and moisture. Change out of wet swimsuits or sweaty workout clothes promptly. Keep the vulvar area clean and dry, but skip scented soaps, douches, and feminine sprays, all of which can disrupt the natural balance of bacteria that keeps yeast in check.
Antibiotics are a common trigger for yeast infections because they kill off protective bacteria along with the ones causing illness. If you notice a pattern of yeast infections during or after antibiotic courses, mention it to your provider. A preventive dose of antifungal medication taken alongside the antibiotic can head it off.
