Most yeast infections clear up within a few days using antifungal creams or suppositories available at any pharmacy without a prescription. These over-the-counter treatments cure 80% to 90% of uncomplicated yeast infections. If you’ve had one before and recognize the symptoms, you can often treat it at home. If it’s your first infection, symptoms are severe, or infections keep coming back, a prescription option may work better.
Over-the-Counter Antifungal Treatments
The two most common OTC antifungals are miconazole (Monistat) and clotrimazole (Gyne-Lotrimin). Both come as vaginal creams and suppositories. They work by breaking down the outer membrane of yeast cells, which causes the cells to leak and die. You have several options depending on how quickly you want to finish treatment:
- 1-day treatment: A single high-dose miconazole suppository (1,200 mg) or a single application of tioconazole ointment.
- 3-day treatment: Miconazole or clotrimazole cream applied nightly for three nights, or miconazole suppositories for three nights.
- 7-day treatment: A lower-concentration cream or suppository used nightly for a full week.
Shorter courses are just as effective for mild to moderate infections. The 7-day regimens use a gentler concentration and may cause less local irritation, which some people prefer. Whichever you choose, finish the full course even if symptoms improve after a day or two.
Prescription Options
A single 150 mg dose of fluconazole, taken by mouth, is the most common prescription treatment. It’s a pill rather than a cream, which many people find more convenient. Fluconazole works the same way topical treatments do, disrupting the yeast cell membrane from the inside. Most people notice symptom relief within 24 to 48 hours.
For severe infections with intense swelling, redness, or cracking, a stronger approach is typical: either 7 to 14 days of a topical antifungal or two doses of fluconazole spaced 72 hours apart. Prescription-only vaginal creams like terconazole are another option your provider may suggest, particularly if OTC products haven’t worked well for you in the past.
Managing Itching While You Wait
Antifungals take time to work, and the itching and burning can be intense in the first day or two. A low-potency hydrocortisone cream (1%, available OTC) applied to the external vulvar skin can take the edge off. Keep it to the outside only, use it for less than two weeks, and stop once the itching subsides. Do not use combination steroid-antifungal products, as the steroid component in those is often too strong and can thin delicate skin.
Cool compresses and a lukewarm (not hot) bath can also reduce irritation. Avoid scented soaps, douches, and bubble baths, all of which can worsen inflammation.
What to Do About Recurring Infections
If you get four or more yeast infections in a single year, that’s considered recurrent. Each individual episode still responds to standard antifungals, but a longer initial treatment is needed to fully knock the yeast back: 7 to 14 days of topical cream or three doses of fluconazole spread over a week (on days 1, 4, and 7). After that, a weekly dose of fluconazole for six months helps prevent the infection from returning.
Boric acid vaginal suppositories are another tool for recurrent or resistant infections, particularly those caused by less common yeast strains that don’t respond well to standard antifungals. The typical protocol is one capsule inserted vaginally at bedtime for two weeks to treat a current infection, then twice a week for 6 to 12 months to prevent recurrence. Boric acid capsules are available without a prescription, but this is a treatment to discuss with a provider first, since boric acid is toxic if swallowed and should never be used during pregnancy.
Do Probiotics Help?
There is real evidence behind probiotics for yeast infections, though they work best alongside antifungal treatment rather than on their own. A meta-analysis of five clinical trials found that adding Lactobacillus-based probiotics to standard antifungal therapy improved short-term cure rates by 14% and cut the one-month relapse rate by 66%. The strains with the most evidence behind them include L. acidophilus, L. rhamnosus, and L. rhamnosus combined with lactoferrin (a protein naturally found in breast milk and other secretions).
Both oral and vaginal probiotic capsules were used across these studies. For preventing recurrence, one effective protocol involved taking an oral probiotic during antifungal treatment and then continuing it for several days each month around the premenstrual period, when estrogen shifts make the vaginal environment more hospitable to yeast. Probiotics aren’t a replacement for antifungals, but they appear to meaningfully reduce the chance of the infection bouncing back.
Home Remedies: What Works and What Doesn’t
Tea tree oil has antifungal properties in lab settings, but applying it vaginally is risky. Even on regular skin, tea tree oil commonly causes irritation, burning, stinging, and allergic rashes. Vaginal tissue is far more sensitive, and there are no clinical trials supporting its use for yeast infections. The potential for harm outweighs any theoretical benefit.
Inserting yogurt, garlic, or coconut oil are popular suggestions online, but none have been tested in rigorous human trials. Yogurt does contain Lactobacillus, but not in standardized amounts, and the sugar content may actually feed yeast growth. Given that proven OTC antifungals cost under $15 and work within days, there’s little reason to experiment with kitchen remedies.
Preventing the Next One
Some infections are unavoidable, but a few habits lower your risk. Wear cotton underwear and avoid tight, non-breathable clothing, especially after exercise. Keep the vulvar area clean and dry, changing out of wet swimsuits or sweaty workout clothes promptly. Skip scented tampons, pads, sprays, and douches, all of which can disrupt the natural balance of vaginal bacteria that keeps yeast in check.
Antibiotics are one of the most common triggers for yeast infections because they kill off the protective Lactobacillus bacteria in the vagina along with whatever infection they’re targeting. If you notice a pattern of yeast infections after antibiotic courses, let your provider know. They may recommend a preventive dose of fluconazole or a probiotic alongside the antibiotic. People with poorly controlled diabetes or conditions that suppress the immune system are also at higher risk, and keeping those conditions well-managed reduces the frequency of yeast infections.
