Most vaginal yeast infections clear up within 3 to 7 days using antifungal creams, suppositories, or a single oral pill, all of which work by disrupting the yeast’s ability to build and maintain its cell walls. The right treatment depends on whether this is a one-time infection, a severe episode, or a recurring pattern.
Over-the-Counter Options
If this is your first or occasional yeast infection with mild to moderate symptoms, over-the-counter antifungal products are the standard starting point. These come as vaginal creams, ointments, and suppositories, and you’ll find them at any pharmacy without a prescription. The most common active ingredients are clotrimazole (sold as Lotrimin AF or Mycelex) and miconazole (sold as Monistat).
You have flexibility in how long you use them. A 7-day course uses a lower-concentration cream or a 100 mg suppository applied nightly. A 3-day course uses a higher concentration, such as miconazole 200 mg suppositories or a 4% cream. There’s also a single-day option: a miconazole 1,200 mg suppository or tioconazole 6.5% ointment applied once. All of these have similar cure rates for uncomplicated infections. The shorter courses aren’t necessarily faster at relieving symptoms; they just deliver a higher dose per application.
Most people notice itching and burning start to improve within the first day or two, but you should complete the full course even if symptoms fade early. Stopping too soon can leave enough yeast behind for the infection to bounce back.
Prescription Treatments
If you’d rather skip vaginal products altogether, a single 150 mg dose of fluconazole, taken by mouth, is the most widely prescribed alternative. It’s effective for uncomplicated infections, and many people prefer the convenience of one pill. For severe symptoms, a second dose 72 hours after the first is sometimes needed.
Prescription vaginal options also exist, including terconazole cream and suppositories and a single-dose butoconazole cream. These tend to be reserved for cases where over-the-counter products haven’t worked or when a healthcare provider suspects a less common yeast species.
Two newer oral medications were recently FDA-approved. Ibrexafungerp (Brexafemme) works differently from traditional antifungals and is taken as two doses in a single day, roughly 12 hours apart. In clinical trials, 50 to 63% of patients had complete symptom resolution within about two weeks, compared to 28 to 45% on placebo. The other, oteseconazole (Vivjoa), is taken by mouth and designed specifically for preventing recurrent infections. These newer drugs are typically reserved for people who haven’t responded well to standard treatments.
How to Tell It’s Actually a Yeast Infection
Before you treat, it’s worth making sure you’re treating the right thing. Yeast infections, bacterial vaginosis (BV), and other vaginal infections share some overlapping symptoms but require completely different medications. Using antifungals for BV won’t help and delays the treatment you actually need.
Yeast infections typically produce a thick, white, cottage cheese-like discharge with significant itching and burning. Pain during intercourse is common. BV, by contrast, causes a thinner, grayish discharge that’s heavier in volume and has a noticeable fishy odor, especially after your period or after sex. BV can cause irritation but rarely causes pain. If your main symptom is odor or thin discharge rather than itching and thick discharge, an antifungal is unlikely to help.
Treating Severe Infections
A yeast infection counts as severe when symptoms are intense: significant redness, swelling, or skin cracking around the vulva. In these cases, a short course of treatment often isn’t enough. CDC guidelines recommend either 7 to 14 days of a topical antifungal or two sequential doses of oral fluconazole spaced 72 hours apart. People with poorly controlled diabetes or weakened immune systems also typically need this longer treatment window, even if symptoms seem mild.
When Infections Keep Coming Back
Recurrent yeast infections, defined as three or more episodes in a single year, affect a meaningful number of people and require a different strategy than treating each episode individually. The goal shifts from curing a single infection to suppressing yeast growth over months.
The standard approach has two phases. First, you clear the current infection with a longer initial course: either 7 to 14 days of topical antifungal therapy or three doses of oral fluconazole taken on days 1, 4, and 7. Once symptoms resolve, you move into a maintenance phase of weekly oral fluconazole for six months. This extended regimen dramatically reduces recurrence while you’re on it.
For infections caused by less common yeast species (such as Candida glabrata, which doesn’t respond well to fluconazole), boric acid vaginal suppositories are an effective alternative. The typical protocol is one 600 mg capsule inserted vaginally each night for 2 to 3 weeks to clear the active infection, followed by twice-weekly use for 6 to 12 months as maintenance. Boric acid is not taken by mouth; it’s used only as a vaginal suppository.
Treatment During Pregnancy
Yeast infections are common during pregnancy, and the treatment rules are straightforward but important. Only topical antifungals (creams and suppositories) should be used, applied for a full 7 days. Clotrimazole and miconazole are both considered safe at any stage of pregnancy and are not associated with birth defects or pregnancy complications.
Oral antifungals, particularly fluconazole, should be avoided during pregnancy. Epidemiologic data links even a single 150 mg dose to a possible increased risk of miscarriage and congenital anomalies, especially when taken during the first trimester.
What to Expect During Treatment
With vaginal creams and suppositories, you’ll typically insert the product at bedtime so it stays in place overnight. Some mild burning or irritation at the application site is normal, especially with the first dose. Wearing a panty liner is practical since some product leaks out. Avoid using tampons during treatment, as they can absorb the medication.
Oral fluconazole works systemically, so you won’t feel anything at the site immediately. Symptom relief usually begins within 24 hours but full resolution takes several days. If your symptoms haven’t improved at all after 3 days of any treatment, or if they worsen, the infection may be caused by a resistant yeast species or may not be a yeast infection at all. That’s when lab testing becomes valuable to identify exactly what’s going on.
