You may shower in the morning, but it is not required. Monistat 3- and 7-day topical yeast infection treatments (miconazole cream, ointment, ovule or suppositories) are inserted into the vagina before bedtime. Lie down as soon as possible after inserting the product to help reduce leakage. During the day, you may want to wear deodorant-free pads or panty shields to protect your clothing as needed.
