Monistat 1 is a single-dose vaginal ovule (a soft, egg-shaped insert) that treats yeast infections with one application. The package typically includes a prefilled applicator containing the ovule and a small tube of external anti-itch cream. Here’s exactly how to use both.
Before You Start
Wash your hands thoroughly with soap and water. Open the package and remove the prefilled applicator. You don’t need to unwrap or handle the ovule itself; it’s already loaded inside the applicator and ready to go.
You can use Monistat 1 at bedtime or during the day. A clinical study comparing bedtime and daytime application of the 1200 mg miconazole ovule found that both were equally effective and well tolerated. That said, lying down after insertion helps keep the ovule in place while it dissolves, so bedtime is the most popular choice.
How to Insert the Ovule
Lie on your back with your knees bent and feet flat, or stand with one foot raised on a chair or the edge of a bathtub. Either position works. Gently insert the applicator into the vagina as far as it comfortably goes. Push the plunger all the way in to release the ovule, then slowly withdraw the applicator. Throw the applicator away after use.
The ovule will dissolve on its own over several hours. You’ll likely notice some leakage, which is normal. Wearing a panty liner, especially overnight, helps keep things comfortable. Avoid using tampons while the medication is working, as they can absorb the medicine before it has a chance to treat the infection.
Applying the External Cream
If your package includes the external anti-itch cream, squeeze a small amount onto your fingertip and apply it to the irritated skin around the outside of the vagina (the vulva). This cream is only for external use. You can apply it up to twice a day for relief from itching and irritation while the internal ovule does its work. Wash your hands again afterward.
What to Expect Afterward
Don’t expect overnight results. Most women do not get complete relief in just one day. What typically happens is some improvement within the first 24 hours, with itching and discharge gradually easing, and complete relief by day seven. The “1” in Monistat 1 refers to the single application, not a one-day cure.
If your symptoms haven’t improved at all after three days, that’s a signal to check in with a doctor. And if symptoms persist beyond seven days, or return within two months, the infection may not be yeast at all and needs a proper diagnosis.
Burning and Irritation After Use
Mild burning, itching, or irritation after inserting the ovule is a known side effect. The 1200 mg dose in Monistat 1 is the strongest concentration available over the counter, and some women find it more intense than the 3-day or 7-day versions. This temporary flare usually settles within a few hours.
If the burning becomes severe, or you notice significant swelling, stop using the product. Intense irritation can sometimes indicate an allergic reaction or that you’re dealing with something other than a yeast infection, such as bacterial vaginosis or a sexually transmitted infection, which require different treatment.
Condoms, Sex, and Timing
Both the ovule and the external cream are oil-based, which means they can weaken latex condoms and diaphragms. If you rely on either of those for birth control or STI protection, they may not work properly during treatment. It’s best to avoid vaginal intercourse while the medication is active and for several days after, both for effectiveness and comfort.
Pregnancy and Other Precautions
If you’re pregnant, talk to your healthcare provider before using Monistat 1. Topical and vaginal miconazole are not well absorbed into the body, so they’re generally considered unlikely to increase risks to a pregnancy. Studies at low doses have not shown an increased chance of birth defects. Still, it’s important to confirm the infection is actually yeast before treating it on your own, since other types of vaginal infections require entirely different medication.
If this is your first yeast infection, or you’re unsure whether your symptoms are from yeast, an accurate diagnosis matters more than speed. Monistat 1 only treats fungal infections caused by Candida. Using it for the wrong condition won’t help and can delay the treatment you actually need.
