Mirena Coil Removal and Insertion

Mirena coil removal and re-fitting


The Mirena coil is an intrauterine device (IUD) that can be used safely to deliver reliable contraception to premenopausal women for up to five years.


The Mirena coil doesn’t carry the risk of side effects related to birth control methods that use estrogen. It can also be used safely while breastfeeding.  Once removed, fertility will return to normal within a few days.


How does the Mirena coil work?


The Mirena coil is a T-shaped plastic frame that is inserted into the uterus by a doctor. It then releases a type of hormone called progestin. This hormone then thickens the mucus found in the cervix which prevents sperm from reaching or fertilising an egg. The lining of the uterus is thinned, and ovulation is partially suppressed. For some women, it can also prevent the release of an egg, but most women will continue to ovulate. The Mirena coil can also sometimes be used to prevent severe menstrual pain, heavy menstrual bleeding, fibroids, and endometriosis.


Are there any side effects?


In most cases, any side effects are mild. Some women may experience headaches, acne, and breast tenderness after the Mirena coil has been settled. These will usually ease over time. Some people may experience changes in mood. A very uncommon side effect is that some women may develop small fluid-filled cysts on their ovaries. These will usually disappear without treatment.

What is the removal and insertion process?


If a woman is looking to have her existing Mirena coil removed and a new one inserted the procedure is simple and quick. The existing Mirena coil will be removed by forceps to pull the string of the Mirena coil. The arms of the device should then fold to allow for easy removal.  If the strings are missing, the doctor may need to use a sonogram or X-ray to locate the device. In these cases, the doctor may need to dilate the cervical canal.


If a woman wishes to have a new device inserted, this will involve using the same instrument as is used when having a smear test. You may experience some mild cramp-like discomfort during the insertion, although this will usually settle shortly after the procedure. In some cases, local anaesthetic may be used.

Your doctor will be able to explain the procedure in more detail and answer any questions that you may have.


Why is it best to get this done privately?


Having your Mirena coil removed and replaced privately allows you to enjoy a more relaxed and comfortable experience. You can have the procedure carried out at a time of your choosing, making it easier to fit into a busy lifestyle.
