Quick answerOver-the-counter vaginal yeast infection treatments such as Monistat use miconazole nitrate, a vaginal antifungal, in 1-day, 3-day and 7-day courses. They differ in strength per dose, not in the active ingredient: Monistat 1 uses a single 1200 mg insert, Monistat 3 uses three 200 mg inserts, and Monistat 7 uses 2% cream for 7 nights. The labels say use them only if a doctor has diagnosed a vaginal yeast infection before, and to ask a doctor first if this is your first time, you have fever, pain or foul-smelling discharge, or you get infections often. Stop and ask a doctor if symptoms do not improve in 3 days or last more than 7 days.

Who should use OTC treatment

The Monistat labels say do not use them if you have never had a vaginal yeast infection diagnosed by a doctor. OTC treatment is meant for people who recognize the symptoms from a past, confirmed infection.

Ask a doctor before use if you have:

While using it

Read the enclosed consumer information leaflet before use, as the labels direct. For period products to use after treatment, see our period underwear guide.

1-day, 3-day or 7-day?

All three use the same antifungal. The 1-day option puts the full course into a single higher-strength insert, while the 7-day cream spreads lower-strength doses over a week. Some people prefer the shorter courses for convenience; others prefer the cream for its gentler nightly dose. Whichever you choose, the labels say that if you do not get complete relief, ask a doctor before using another product.

Whichever course you use, keep track of the day you started. The labels set two checkpoints: symptoms should get better within 3 days, and they should not last more than 7 days. If either checkpoint is missed, stop and see a doctor rather than starting a second box.

When to stop and see a doctor

Stop use and ask a doctor if symptoms do not get better in 3 days, symptoms last more than 7 days, or you get a rash or hives, abdominal pain, fever, chills, nausea, vomiting, or foul-smelling vaginal discharge. If pregnant or breastfeeding, ask a health professional before use. If swallowed, get medical help or contact a Poison Control Center right away.

Itching and discharge can have other causes that need different treatment, so do not keep treating on your own if the pattern keeps coming back. For urinary symptoms, see our at-home UTI test strips guide.

Ingredients and comfort

The Monistat 3 inserts are made with gelatin, glycerin, a hydrogenated vegetable oil base and titanium dioxide, and the external cream includes ingredients such as cetyl alcohol, isopropyl myristate, propylene glycol and stearyl alcohol. If you have sensitivities, compare inactive ingredients before you buy. The Monistat 3 and 7 labels direct use at bedtime, which helps the medicine stay in place overnight. A panty liner can help with leakage; avoid tampons until treatment is finished.
