For a straightforward yeast infection, you can pick up an over-the-counter antifungal cream or suppository at any pharmacy without a prescription. The two most common active ingredients are miconazole (sold as Monistat) and clotrimazole (sold as Mycelex or Lotrimin AF), and both work equally well. A single oral prescription pill is also an option if you prefer not to use a topical product. The right choice depends on how quickly you want relief, how long you’re willing to treat, and whether you’re pregnant or dealing with recurring infections.
OTC Creams and Suppositories
The fastest way to start treating a yeast infection is with an antifungal you can buy without a prescription. These come in three main formats: vaginal creams, vaginal suppositories, and ointments. All of them work by killing the Candida yeast directly at the site of infection.
Your main options on the shelf:
- Miconazole (Monistat): Available as a 7-day cream, a 3-day cream, or a single-day 1,200 mg suppository. The shorter courses use higher concentrations of the active ingredient.
- Clotrimazole (Mycelex, Lotrimin AF): Available as a 7- to 14-day 1% cream or a 3-day 2% cream.
- Tioconazole: A 6.5% ointment applied once in a single dose.
In a head-to-head trial comparing single-dose tioconazole to a 3-day course of clotrimazole, 84% and 85% of patients respectively remained symptom-free four weeks after treatment. The cure rates were nearly identical, so convenience is the real differentiator. If you want to apply something once and be done, tioconazole is a solid pick. If you prefer the wider availability and lower price of miconazole or clotrimazole, a 3-day course is the most popular middle ground.
Topical treatments tend to start relieving itching and burning within about 24 hours, though full symptom resolution takes a few days. Many products include an external anti-itch cream in the box for more immediate comfort.
The Prescription Pill Option
If you’d rather skip the creams entirely, a single 150 mg dose of fluconazole (Diflucan) is the standard oral prescription. You take one pill and you’re done. It works systemically, traveling through your bloodstream to reach the infection, which means it can take a bit longer to kick in. Some studies show symptom relief starting around 24 hours, while others suggest topical treatments may provide comfort a few hours sooner. The practical difference is small.
You’ll need to see a healthcare provider or use a telehealth service to get a prescription. Fluconazole is a good choice when you’ve had yeast infections before, know what you’re dealing with, and just want the simplest treatment possible.
Make Sure It’s Actually a Yeast Infection
Before you buy anything, it’s worth confirming you’re treating the right thing. About two-thirds of women who self-diagnose a yeast infection are wrong, and using the wrong treatment delays actual relief.
The key differences to look for:
- Yeast infection: Thick, white, odorless discharge (often described as cottage cheese-like), along with itching, redness, and swelling around the vulva.
- Bacterial vaginosis: Thin, grayish, foamy discharge with a noticeable fishy smell. Itching is less prominent.
- Trichomoniasis: Frothy, yellow-green discharge that smells bad and may contain spots of blood.
If your symptoms don’t clearly match the yeast infection profile, or if this is your first time experiencing them, getting tested before treating is the safer move. Bacterial vaginosis and trichomoniasis require completely different medications.
What to Get During Pregnancy
If you’re pregnant, stick to topical treatments only. Miconazole and clotrimazole creams and suppositories are considered safe at any stage of pregnancy and don’t cause birth defects or complications. Choose a 7-day formula for the best results.
Oral fluconazole is not recommended during pregnancy, particularly in the first trimester, because of a possible link to miscarriage and birth defects. The newer oral antifungal Brexafemme is also contraindicated during pregnancy.
Treatments for Recurring Infections
If you’re getting three or more yeast infections a year, the standard short-course treatments won’t be enough on their own. Recurrent infections call for a two-phase approach: a longer initial treatment to fully clear the yeast, followed by months of maintenance therapy to keep it from coming back.
The initial phase typically involves 7 to 14 days of a topical antifungal, or three doses of fluconazole spread over a week (on days 1, 4, and 7). After that, weekly fluconazole for six months is the standard maintenance regimen recommended by CDC guidelines. This extended approach significantly reduces the chance of another episode.
Boric Acid for Resistant Strains
Some yeast infections are caused by non-albicans strains of Candida that don’t respond well to the usual antifungal medications. For these, boric acid vaginal suppositories are a recognized second-line treatment. The standard protocol is one 600 mg capsule inserted vaginally each night for two to three weeks to treat an active infection. For ongoing prevention, you can reduce to twice a week for six to twelve months.
Boric acid capsules are available at most pharmacies, or you can make your own using boric acid powder (not crystals) packed into size “0” gelatin capsules. These are for vaginal use only and should never be taken by mouth.
Probiotics as a Supporting Strategy
Probiotics won’t clear an active yeast infection on their own, but specific strains can help restore the balance of bacteria in your vagina and reduce yeast counts over time. The best-studied combination is Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14, two strains originally isolated from the female urogenital tract. In a randomized trial of 64 women, taking these strains orally for four weeks led to a significant increase in protective vaginal lactobacilli and a measurable decrease in yeast colonization compared to placebo.
Look for probiotic supplements that list these specific strains on the label, with at least 1 billion colony-forming units per strain. They’re most useful as an add-on to antifungal treatment or as a long-term strategy if you’re prone to recurrent infections.
Newer Prescription Options
Two newer prescription medications have expanded the options for people who don’t respond to standard treatments. Brexafemme (ibrexafungerp) is the first non-azole antifungal approved for vaginal yeast infections and works through a completely different mechanism than older drugs. It’s approved for adults and post-menarchal adolescents. Vivjoa (oteseconazole) is specifically designed for preventing recurrent yeast infections and offers an alternative to the six-month fluconazole maintenance regimen.
Both require a prescription and are typically reserved for cases where standard treatments have failed or keep failing. Neither is safe during pregnancy.
Choosing the Right Treatment
For most people with an occasional yeast infection, a 3-day miconazole or clotrimazole product from the pharmacy is all you need. If you hate the mess of creams, ask for a fluconazole prescription. If you’re pregnant, use a 7-day topical cream. And if infections keep coming back, talk to a provider about a longer treatment plan that includes maintenance therapy, possibly with boric acid or one of the newer medications added to the mix.
