A yeast infection occurs when a fungus called Candida grows too much in your body. Candida normally lives on your skin and inside your mouth, throat, and digestive system without causing problems. Your body's natural balance of bacteria and yeast keeps everything in check. However, when conditions change—such as when you take antibiotics, experience hormonal shifts, or have a weakened immune system—Candida can multiply rapidly and cause uncomfortable symptoms.

Yeast infections most commonly affect women in the vaginal area, but they can also occur in the mouth (called thrush), skin folds, or other areas. Men can develop yeast infections too, though they're less common. According to the National Institutes of Health, approximately 75% of women will experience at least one vaginal yeast infection during their lifetime. The infection itself is not dangerous, but it can cause significant discomfort and affect your quality of life.
Several factors increase your risk of developing a yeast infection. These include taking broad-spectrum antibiotics, which kill helpful bacteria along with harmful ones; having diabetes with high blood sugar levels; being pregnant; wearing tight, wet clothing; using douches or scented products; and having a weakened immune system from conditions like HIV or certain medications. Understanding your personal risk factors can help you prevent infections from occurring in the first place.
The symptoms of a vaginal yeast infection typically include itching and burning, especially during urination or sexual intercourse; thick, white, cottage cheese-like vaginal discharge; redness and swelling of the vulva; and sometimes a yeasty odor. Oral yeast infections cause white patches in the mouth, redness, and difficulty swallowing. Skin yeast infections appear as red, itchy rashes in skin folds. If you're experiencing these symptoms for the first time, it's important to see a healthcare provider to confirm you actually have a yeast infection, as other conditions can cause similar symptoms.
Practical takeaway: Keep track of your symptoms and any factors that seem to trigger them, such as antibiotic use or hormonal changes. This information helps healthcare providers give you better guidance and prevents unnecessary treatment of infections you might not actually have.
Over-the-counter antifungal medications are widely available for treating yeast infections without a prescription. These medications come in several forms and can be purchased at most drugstores, supermarkets, and online retailers. The most common active ingredients are miconazole, clotrimazole, tioconazole, and tolnaftate. These medications work by disrupting the cell walls of the Candida fungus, causing it to die.

Vaginal creams are one popular option. Products like Monistat contain miconazole nitrate and come in one-day, three-day, or seven-day formulas. The one-day treatments contain higher concentrations of medication and work faster, while seven-day treatments use lower doses. You insert the cream into your vagina using an applicator before bed. Many women prefer creams because they can feel the medication working and can control the application. A seven-day cream treatment typically costs between $8 and $15.
Vaginal tablets or suppositories offer another option. Clotrimazole tablets (brand names include Gyne-Lotrimin) are inserted into the vagina and dissolve over time. These come in three-day or seven-day courses. Some women prefer tablets because they're less messy than creams and don't stain clothing. Tablets usually cost between $10 and $18 for a treatment course.
Oral medications are also available without a prescription in some areas. Fluconazole (Diflucan) is a single-dose oral tablet that treats yeast infections from the inside. You take one tablet by mouth, and it works throughout your body. This option is convenient for women who prefer not to use vaginal treatments, though it may cause mild side effects like headache or nausea in some people. Oral medications typically cost $10 to $20 per dose.
When using any over-the-counter treatment, follow the package directions carefully. Complete the entire course even if symptoms improve before the treatment ends. If your infection doesn't improve within three days or worsens, stop using the medication and contact a healthcare provider. Also note that if you've never had a yeast infection before, seeing a healthcare provider first is wise to confirm the diagnosis, as other conditions require different treatments.
Practical takeaway: Start with a three or seven-day treatment course from a trusted pharmacy brand. Keep the receipt and note the product name and active ingredient. If you need treatment again, you'll know what worked for you. Store all medications at room temperature away from moisture unless the package says otherwise.
Many people turn to home remedies for yeast infection relief, and some have research supporting their use. It's important to understand that while these remedies may help with symptoms, they work differently than antifungal medications and may not eliminate the infection completely. Home remedies can sometimes reduce itching and discomfort while your body's natural defenses or other treatments work.

Plain yogurt with live cultures is one of the most well-known home remedies. The idea is that beneficial bacteria called lactobacillus in yogurt can help restore your body's natural balance. Some women apply plain, unsweetened yogurt directly to the affected area or insert it into the vagina using an applicator. Research on yogurt's effectiveness shows mixed results—some studies suggest it may help, while others find no significant benefit. If you try this method, use plain yogurt without added sugars, which would actually feed the yeast. Apply it once or twice daily and stop if it causes irritation.
Boric acid is a naturally occurring substance that has antifungal properties. Some studies suggest boric acid suppositories may be effective for yeast infections, especially stubborn ones. However, boric acid is toxic if swallowed, so it should never be used vaginally if you're pregnant or if you might have a puncture in your vaginal tissue. If you're considering boric acid, research reputable suppliers and follow safety guidelines carefully. It typically costs $5 to $10 for a treatment course.
Tea tree oil is another remedy people mention, but it requires caution. While tea tree oil does have antifungal properties, applying it directly to skin can cause irritation and burning. If you want to try tea tree oil, dilute it heavily with a carrier oil like coconut oil—never apply it undiluted. Some people add a few drops of diluted tea tree oil to bathwater. Always do a patch test on a small area first to check for allergic reactions.
Apple cider vinegar baths are sometimes suggested as a soothing remedy. Adding one to two cups of apple cider vinegar to a lukewarm bath and soaking for 15-20 minutes may help reduce itching temporarily. The acidity might create an environment less favorable for yeast growth, though scientific evidence is limited. This method is generally safe but won't treat the underlying infection on its own.
Garlic contains allicin, a compound with antifungal properties. Some people eat more garlic or apply crushed garlic to affected areas. However, raw garlic can irritate sensitive skin, and eating garlic alone won't eliminate a yeast infection. If you want to increase garlic intake, use it in your cooking rather than applying it directly to skin.
Practical takeaway: Home remedies work best as symptom relief while you use proven treatments. If you choose a home remedy, use it alongside—not instead of—over-the-counter or prescription antifungals for the best results. Stop any remedy if it causes increased irritation or burning.
Preventing yeast infections is often easier than treating them. Understanding which daily habits contribute to yeast overgrowth allows you to make changes that reduce your infection risk significantly. Many prevention strategies are simple adjustments that don't require any medication or special products.

Clothing choices matter more than many people realize. Yeast thrives in warm, moist environments. Tight-fitting pants, nylon underwear, and synthetic fabrics trap moisture and heat, creating ideal conditions for Candida growth. Switch to loose-fitting clothes made from natural fabrics like cotton or moisture-wicking materials. Cotton underwear
