I have a question about the Mirena coil fitting

What is a Mirena coil fitting?

The Mirena coil is a hormonal intrauterine system (IUS), an effective, long-term and reversible method of contraception. The Mirena coil continuously releases small amounts of a contraceptive hormone (progestogen) and works where it is needed in the uterus so you need less hormone than if you were taking the pill. The Mirena coil also stops or minimises periods and reduces painful periods.

What happens during a Mirena coil fitting?

The Mirena coil can be fitted in the outpatient clinic or at your own GP surgery.

The doctor will examine your cervix (neck of the womb) using a speculum, in the same way as when you have a smear test.

A plastic tube containing the IUS is passed through the cervix and into the uterus. The threads hang down through the cervix into the vagina and are cut to about 2 to 3cms (1 inch) in length.

Why would I have a Mirena coil fitting?

You might have a Mirena coil fitted in order to treat heavy periods (menorrhagia) and as protection for the lining of the uterus (womb) during menopause.

What should I expect after a Mirena coil fitting?

Most women find that fitting the IUS causes only little discomfort. However, for some women it may be uncomfortable. You may wish to discuss the need for pain killers or local anaesthetic with your doctor.

You will need to check that the Mirena is still in place about month after insertion and visit your doctor for a yearly check-up.

You will be able to resume normal activities immediately.

The IUS can stay in place for 5 years - 4 years if used as a form of Hormone Replacement therapy (HRT).
