Common questions about Micro-Guard

How long do you have to lay down for after using Monistat?
Most women use Monistat (miconazole) right before bedtime, and then lay down for the rest of the night while sleeping. For best results, lie down as soon as possible after inserting the product. This can help prevent significant leakage. You may want to wear a deodorant-free pad or panty shield to help protect your clothing as needed. Do not use tampons during Monistat treatment because tampons may remove some of the medicine from the vagina. Continue reading
Do you wash Monistat out in the morning?
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.
