During your appointment your doctor or nurse can talk you through everything and make sure you're happy to proceed.
When you are comfortable and ready, Mirena is placed in the womb using a thin tube. Once inside, it opens into the 'T' shape and the two small threads at the bottom of Mirena are cut to the right length.
Your doctor or nurse will teach you how to check that your Mirena is in place by finding and feeling the threads.
You may experience some pain and/or dizziness during the placement. If you are epileptic, please tell your doctor or nurse.
Once it is fitted, you should not be able to feel your Mirena.
Placing Mirena may feel similar to a smear test, so some women may feel uncomfortable. Your doctor or nurse can advise you on ways to minimise discomfort ahead of your appointment.
You may want to bring a panty liner in case there is a little bleeding following the fitting.
Before you have your Mirena fitted, you may have to collect it from the pharmacy. It comes in a box that'll look big for such a small contraceptive, but don't worry. This is because the box contains everything that is needed to comfortably and quickly fit Mirena, not just the Mirena itself.
You don't need to worry about doing anything with your Mirena at this point, you just need to remember to bring it with you to your appointment. Your doctor or nurse will handle the rest.
After insertion, you may feel some pain similar to menstrual cramps. However, this usually disappears within a few days. If you experience severe pain, fever or heavy bleeding after Mirena is inserted, or if pain/bleeding persists for more than a few weeks, please make an appointment to see your doctor or nurse.
You should be offered a check-up 4-6 weeks after placement to make sure everything is going okay.
At the end of the fourth or fifth year, depending on what you have been prescribed for, your Mirena should be taken out by your doctor or nurse.
If you wish to continue using Mirena, you can get a new one placed during the same appointment.
There are several reasons why you may choose to remove Mirena. Here, you'll find information about getting pregnant after using Mirena and continuing to prevent pregnancy after Mirena is removed.
I need a new one
Mirena can remain in the uterus for up to 5 years to prevent pregnancy, and heavy periods. If you choose to continue using Mirena, you'll make an appointment with your healthcare professional to remove Mirena and place a new one. Your new IUD can be placed immediately after the removal of your old one.
I want to get pregnant
If you are removing Mirena because you want to get pregnant, you can start trying as soon as Mirena has been removed. Your healthcare provider can remove Mirena at anytime, you may become pregnant as soon as Mirena is removed.
I no longer want to use Mirena
Mirena is intended for use up to 5 years, but you can stop using Mirena at anytime by asking your healthcare provider to remove it. You could become pregnant as soon as Mirena is removed, so you should use another method of birth control if you do not want to become pregnant. Talk to your healthcare provider about the best birth control methods for you, because your new method may need to be started 7 days before Mirena is removed to prevent pregnancy.
If you've made the decision with your healthcare provider to remove Mirena for any of the reasons above, they can do so during a routine office visit. Removing Mirena does not require surgery, but you may experience some pain, bleeding, dizziness, or have vasovagal reactions (feeling faint/passing out, or seizure in patients with epilepsy). Talk with your healthcare provider if you have other questions about the removal process.
