Most yeast infections are treated with antifungal medications available over the counter as creams, ointments, or suppositories, or as a single-dose prescription pill. For a straightforward, uncomplicated infection, either route works well, and the choice often comes down to whether you prefer a topical treatment or a one-and-done oral option.
Over-the-Counter Creams and Suppositories
The most common first step is an OTC antifungal cream or vaginal suppository. These contain one of a few closely related active ingredients: clotrimazole (Gyne-Lotrimin), miconazole (Monistat), or tioconazole (Vagistat-1). All of them work the same way, disrupting a key building block in the yeast cell’s outer membrane so it can no longer survive.
You’ll see these sold in 1-day, 3-day, and 7-day treatment kits. The active ingredient concentration is higher in the shorter courses, so the total amount of medication you use is roughly the same regardless of which you pick. A 7-day course tends to cause less local irritation because the daily dose is gentler, while a 1-day treatment is more convenient but can feel more intense. If you’ve never treated a yeast infection before, the 7-day option is a reliable starting point.
Most kits also include a small tube of external cream you can apply to the vulva for itch relief while waiting for the internal treatment to work. Symptoms like itching and burning typically begin to ease within two to three days, but it’s important to finish the full course even if you feel better sooner. Stopping early increases the chance the infection comes back.
The Prescription Pill: Fluconazole
Fluconazole (Diflucan) is the standard prescription option. For an uncomplicated yeast infection, the typical treatment is a single 150 mg pill taken by mouth. That’s it. Most people notice symptom relief within one to two days, though it can take up to 72 hours for the medication to fully clear the infection. About 96% of women report improved quality of life after treatment with fluconazole.
Because it’s a pill rather than a topical, fluconazole is absorbed into your bloodstream. That makes it effective but also means it can cause mild side effects like nausea, headache, or stomach upset. Serious side effects are rare, but liver problems can occur with prolonged use. Your doctor or pharmacist will check whether fluconazole interacts with anything else you take, since it can affect how your body processes certain other medications.
Fluconazole requires a prescription in the United States, so you’ll need to see a healthcare provider or use a telehealth visit to get it. Many providers are comfortable prescribing it based on your symptom description alone if you’ve had a confirmed yeast infection before.
Treatment for Recurrent Infections
If you get four or more yeast infections in a year, your situation is classified as recurrent, and a single dose of anything is unlikely to keep the problem at bay. The standard approach is a loading regimen of fluconazole: 150 mg on day 1, day 4, and day 7, followed by a 150 mg maintenance dose once a week for six months.
This extended schedule works well at suppressing infections while you’re on it, but recurrence after stopping is common. Roughly 63% of women still experience infections after completing maintenance therapy. If that happens, your provider may recommend a second round or explore alternative medications.
Boric Acid for Resistant Infections
When standard antifungals don’t work, boric acid vaginal suppositories are sometimes used as a second-line option. These contain 600 mg of boric acid per suppository, inserted vaginally at bedtime. A typical course lasts 7 to 14 days. Boric acid is particularly useful against yeast strains that are naturally resistant to the usual antifungal medications, such as Candida glabrata.
Boric acid is not an oral medication. Swallowing it is toxic. It’s also not appropriate during pregnancy. But as a vaginal suppository for stubborn or recurring infections that haven’t responded to other treatments, it has a solid track record in clinical use.
What to Use During Pregnancy
Yeast infections are especially common during pregnancy, and the treatment options narrow considerably. Only topical antifungal creams or suppositories applied for a full 7 days are recommended. The CDC guidelines specifically warn against oral fluconazole during pregnancy because even a single 150 mg dose has been associated with miscarriage and birth defects in epidemiologic studies. If you’re pregnant and dealing with a yeast infection, stick with a 7-day OTC cream like miconazole or clotrimazole and let your OB-GYN know.
Side Effects to Expect
Topical treatments commonly cause mild local irritation: burning, stinging, or increased itching right after application. This usually fades within 20 to 30 minutes and tends to lessen with each day of treatment. If the irritation is severe or you develop a rash, you may be reacting to an ingredient in the product rather than experiencing a normal side effect.
Oral fluconazole more commonly causes stomach-related issues: abdominal pain, nausea, and occasionally diarrhea. These are typically mild and resolve quickly since you’re only taking a single dose. In rare cases, antifungal medications can cause liver damage or severe allergic reactions, but these are far more associated with prolonged or high-dose use than with the short courses used for yeast infections.
How to Choose the Right Option
If this is your first yeast infection, or you’re not entirely sure that’s what’s going on, getting a diagnosis before treating is worthwhile. Bacterial vaginosis and certain sexually transmitted infections can mimic yeast infection symptoms, and antifungal medication won’t help with those.
If you’ve had yeast infections before and recognize the symptoms, an OTC cream or suppository is a reasonable place to start. Choose the 7-day version if you want fewer side effects, or the 1-day version if convenience is the priority. If you’d rather skip the mess of topical treatments entirely, ask your provider for a fluconazole prescription.
For infections that come back frequently, don’t respond to OTC treatment within a week, or occur during pregnancy, working directly with a healthcare provider gives you access to the extended regimens and alternative therapies that OTC products can’t offer.
