1-Day, 3-Day or 7-Day Yeast Infection Treatment: What to Check Before You Buy

The drugstore shelf offers yeast infection treatments in 1-day, 3-day and 7-day versions, as creams, suppositories or combination packs. They contain antifungal medicines such as miconazole, clotrimazole or tioconazole. Here is how the options compare and the checks to make before you open a box.

Do the short courses work?

The CDC’s¹ treatment guidelines list over-the-counter clotrimazole, miconazole and tioconazole products among recommended treatments for yeast infections. Single-dose and 1- to 3-day topical treatments effectively treat uncomplicated infections, and azole treatment relieves symptoms in 80% to 90% of people who finish it.¹

The difference is mostly in strength and convenience: shorter courses use a higher dose. The CDC¹ also lists a prescription single-dose fluconazole pill as an option.¹ If you aren’t sure which length suits you, ask a pharmacist.

Check 1: Are you sure it’s yeast?

The Drug Facts label says not to use the product if a doctor has never diagnosed you with a vaginal yeast infection, and to ask a doctor first if this is your first time with vaginal itching and discomfort.²

The CDC¹ adds that even women who’ve had a yeast infection diagnosed before aren’t necessarily better at diagnosing themselves, and that using these products when it isn’t yeast can delay treatment of other causes.¹ After menopause, itching and irritation can also come from thinning vaginal tissue. Our guides to yeast, BV or UTI and genitourinary syndrome of menopause can help you sort out what to ask.

Check 2: Do you take warfarin?

The label advises asking a doctor or pharmacist before use if you take the blood thinner warfarin, because bleeding or bruising may occur.²

Check 3: Any warning symptoms?

Ask a doctor before using one if you have lower belly, back or shoulder pain, fever, chills, nausea, vomiting or a foul-smelling discharge. The label warns you may have a more serious condition.²

Check 4: How often does this happen?

The label says to ask a doctor if you get yeast infections often, such as once a month or three in six months, because diabetes or a weakened immune system can be a cause.² The CDC¹ also treats infections in women with diabetes, or those that keep returning, as more complicated cases that may need a longer course.¹ Our article on why yeast infections keep coming back covers more.

While you’re using it

• Condoms and diaphragms may fail. The CDC¹ notes these creams and suppositories are oil based and might weaken latex.¹²
• Skip tampons, douches, spermicides and other vaginal products, and don’t have vaginal sex during treatment.²
• Mild extra burning or itching can happen at first.²

When to stop and get checked

Stop and see a doctor if symptoms don’t improve in 3 days, last more than 7 days, or you get a rash, hives, belly pain, fever or foul-smelling discharge.² The CDC¹ says anyone whose symptoms persist after an over-the-counter product, or return within two months, should be examined and tested.¹ It also found no strong evidence for probiotics or homeopathic products as treatment.¹

Try: “I’ve had itching for a week and tried a 3-day cream without relief. Can you test what’s causing it, and could it be related to menopause instead of yeast?”
