Monistat 3 is a three-day vaginal yeast infection treatment that comes with three suppositories and a small tube of external cream. You insert one suppository per night at bedtime for three consecutive nights, using the included applicator each time. Here’s exactly how to use both components for the best results.
What’s in the Box
The Monistat 3 combination pack contains two separate products that work together. The suppositories treat the infection internally, while the cream handles external symptoms like itching around the vulva.
- 3 vaginal suppositories, each containing 200 mg of miconazole nitrate (the antifungal that kills yeast)
- 1 tube of external cream (9 grams), containing 2% miconazole nitrate for itching and irritation on the skin outside the vagina
Some versions come with disposable applicators, while others use prefilled applicators. Either way, each applicator is single-use. Throw it away after insertion.
How to Insert the Suppository
Use the suppositories at bedtime. Lying down helps the medication stay in place overnight rather than leaking out during the day. Before you start, wash your hands thoroughly.
If your kit includes separate applicators and suppositories, unwrap one suppository from the blister pack and place it into the open end of the applicator. If your kit has prefilled applicators, you can skip this step. Lie on your back with your knees bent, or stand with one foot elevated on a step or the edge of the bathtub. Gently insert the applicator into the vagina as far as it will comfortably go, then push the plunger to release the suppository. Remove the applicator and throw it away.
Repeat this process at bedtime on the second and third nights. Use all three suppositories even if your symptoms disappear after the first or second night. Stopping early can leave the infection partially treated, making it more likely to come back.
How to Apply the External Cream
The small tube of cream is for the itchy, irritated skin outside the vagina only. It does not go inside. Squeeze a small amount onto your fingertip and gently apply it to the affected area. You can use the cream up to twice a day for up to seven days as needed. Wash your hands before and after application.
This cream provides relief while you wait for the suppositories to clear the underlying infection. Many people find the external itching is the most uncomfortable part of a yeast infection, so this component can make the treatment days much more manageable.
What to Expect During Treatment
A mild increase in vaginal burning, itching, or irritation is normal right after inserting the suppository. This is a reaction to the medication and usually fades within a short time. It doesn’t mean the treatment isn’t working or that you’re having an allergic reaction.
You may notice some discharge or leakage overnight or in the morning. Wearing a pad (not a tampon) can help with this. Symptoms like itching and discomfort often start improving within the first couple of days, but the infection needs the full three-day course to be properly treated. If your symptoms haven’t improved at all after three days, or you still have symptoms after seven days, that’s a sign something else may be going on.
Periods, Condoms, and Other Timing Concerns
You can use Monistat 3 during your menstrual period. If your period starts mid-treatment, keep going and finish all three nights. Do not use tampons during treatment, though, because they can absorb the medication and pull it out of the vagina. Stick to pads and change them frequently.
Miconazole can weaken latex condoms and diaphragms. These birth control methods may not work reliably during treatment and for a short time afterward. If you’re sexually active during your treatment window, be aware that your usual barrier method may not protect against pregnancy or sexually transmitted infections.
Signs You May Need a Different Approach
Monistat 3 works well for straightforward vaginal yeast infections, but it’s not the right call for every situation. If this is your first yeast infection ever, your symptoms feel different from past infections, or the treatment that worked before isn’t working now, it’s worth getting evaluated rather than self-treating.
Recurring yeast infections, defined as four or more within a single year that aren’t related to antibiotic use, deserve a closer look. Repeated infections can sometimes signal an underlying issue, or the symptoms may actually be caused by something other than yeast. If your symptoms get worse during treatment rather than better, that’s also a reason to get checked out rather than push through the remaining doses.
