What to expect during placement of Mirena


Placement of Mirena is nonsurgical. Mirena is placed in your uterus by your healthcare provider during a routine office visit and typically takes only a few minutes.

Everyone is different, and some women may experience discomfort or spotting during or after placement. Cramps, dizziness, and/or some bleeding may occur and are common side effects. Ask your healthcare provider about over-the-counter pain medications to help minimize cramps.

Let your healthcare provider know if your side effects are severe or last more than 30 minutes as Mirena may not have been properly placed.

At placement, your healthcare provider will:

Apply an antiseptic solution to your vagina and cervix

Pass a slim tube of flexible plastic (the inserter) containing Mirena into your vagina and then into your uterus

Check to make sure Mirena is positioned correctly

Withdraw the plastic inserter, leaving Mirena in your uterus

Ensure that the two threads attached to the stem of Mirena properly extend through your cervix, which help ensure that Mirena is properly placed. This will also help with the removal of Mirena by your healthcare provider when that time comes

Trim the threads to the appropriate length

Before you leave your healthcare provider's office:

Have your healthcare provider explain how to do a self-check of the threads of your Mirena once a month

Schedule a follow-up appointment with your healthcare provider within 4 to 6 weeks. He or she will want to check to see if your Mirena is properly in place

Consider scheduling your annual check-up at the same time so that you don't forget. Your healthcare provider should check your Mirena once a year as part of a routine physical
