If you think you have a yeast infection, the first step is figuring out whether that’s actually what’s going on. About two-thirds of women who self-diagnose a yeast infection turn out to have something else entirely. The symptoms overlap heavily with other common conditions, so getting this right matters before you spend money on treatment that won’t work.
Make Sure It’s Actually a Yeast Infection
The hallmark of a yeast infection is intense itching and irritation around the vulva, often accompanied by a thick, white discharge that looks like cottage cheese. You may also notice burning during urination or pain during sex. The discharge typically has little to no odor.
Bacterial vaginosis, which is just as common, looks different. BV produces a thin, grayish discharge that’s heavier in volume and has a noticeable fishy smell, especially after your period or after sex. BV is caused by a shift in vaginal pH rather than a fungal overgrowth, and it requires a completely different treatment. Using an antifungal cream for BV won’t help and can delay the care you actually need.
Trichomoniasis, a sexually transmitted infection, can also mimic yeast infection symptoms with itching and irritation, but it often causes a frothy, yellow-green discharge and a strong odor. If your symptoms don’t match the classic yeast infection pattern (itching plus thick white discharge, minimal smell), you’re better off seeing a healthcare provider before treating on your own.
What About At-Home pH Tests?
You can buy vaginal pH test strips at most pharmacies. These are practically identical to the ones doctors use, and the FDA says they show good agreement with a doctor’s diagnosis. But there’s a significant catch: pH changes alone can’t tell you which type of infection you have, and they can’t confirm a yeast infection at all. A normal pH reading (meaning acidic, around 4.5 or lower) actually suggests you might have a yeast infection rather than BV, since yeast overgrowth doesn’t typically raise pH the way bacterial infections do. But a normal result could also just mean nothing is wrong.
Your doctor uses a combination of pH testing, microscopic examination, cultures, and your medical history to make a diagnosis. A single pH strip at home can’t replicate that. These tests are most useful as a screening tool: if your pH comes back elevated, you probably don’t have a simple yeast infection and should see a provider.
Treating It With Over-the-Counter Medication
If you’ve had a yeast infection before and recognize the symptoms clearly, OTC antifungal treatments are a reasonable next step. The three main options available without a prescription are miconazole (sold as Monistat), clotrimazole (sold as Trivagizole), and tioconazole. All come as vaginal creams or suppositories that you insert using an included applicator.
The biggest choice you’ll make is treatment duration. Miconazole comes in a 1-day, 3-day, or 7-day version. Clotrimazole comes in 3-day and 7-day versions. The shorter courses use higher concentrations of the medication. All are effective, but the 7-day option tends to cause less local irritation, which can matter if your symptoms are already intense. The 1-day treatments are convenient but can sometimes cause a temporary burning sensation from the concentrated dose.
You should not use hydrocortisone cream inside the vagina for itch relief while waiting for treatment to kick in. The antifungal creams themselves provide the most reliable relief because they address the underlying cause. External antifungal cream (many products include a separate tube for the vulva) can help soothe itching on the outer skin while the internal treatment works.
When OTC Treatment Isn’t the Right Call
Self-treatment makes sense if this is a straightforward repeat episode with familiar symptoms. But several situations call for a doctor’s visit instead:
- First-time symptoms. If you’ve never had a confirmed yeast infection before, get a proper diagnosis rather than guessing.
- Pregnancy. Some antifungal products aren’t safe during pregnancy, and your provider needs to guide treatment.
- Frequent infections. If you’re getting four or more yeast infections per year, that’s considered recurrent and often requires a different treatment approach, typically a prescription oral antifungal.
- Severe symptoms. Significant swelling, redness, or cracking of the vulvar skin suggests a more complicated infection that OTC treatments may not resolve.
- Diabetes or a weakened immune system. These conditions increase your risk of complicated or resistant infections.
- No improvement after treatment. If your symptoms haven’t cleared up after completing an OTC course, what you’re dealing with likely isn’t a straightforward yeast infection.
What a Doctor Can Prescribe
For uncomplicated yeast infections, the standard prescription is a single oral dose of fluconazole. It’s one pill, taken once, and most people find it more convenient than multi-day vaginal treatments. For recurrent infections, your provider may prescribe a longer course or a maintenance regimen to prevent future episodes. A doctor can also run tests to identify the specific strain of yeast involved, since some less common strains don’t respond well to standard antifungals.
Sex, Partners, and Reinfection
A yeast infection is not a sexually transmitted infection, but it can be passed between partners during sex. The likelihood of transmission is small, but it’s not zero. If you have sex while symptomatic or mid-treatment, you risk prolonging the infection, triggering a return of symptoms that had started clearing up, and passing the yeast to your partner. If your partner then develops symptoms, the infection can bounce back and forth between you.
Most doctors recommend waiting until your symptoms have fully resolved before having sex again. Male partners who develop redness, itching, or irritation on the penis after exposure can be treated with a topical antifungal cream. Routine treatment of asymptomatic partners isn’t typically recommended.
Things to Avoid During an Infection
While you’re symptomatic or treating a yeast infection, skip scented soaps, douches, and bubble baths in the vaginal area. Wear breathable cotton underwear and avoid sitting in wet clothing. Coconut oil, sometimes suggested as a home remedy, can actually worsen yeast infections, irritate skin, and break down latex condoms. Talc-based products near the vaginal area are also best avoided, as their safety profile remains uncertain.
Warm water and gentle, unscented soap for the external area are all you need for hygiene during this time. The vagina is self-cleaning internally, and adding products to the mix disrupts the microbial balance that helps keep yeast in check.
