IUD (Mirena) Clinic
A Mirena is an intrauterine device (IUD) which releases progesterone hormone.
- It is a long acting reversible contraceptive which lasts for 5 years.
- The Mirena is used for control of heavy menstrual bleeding. It is the first line treatment recommended by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists for heavy menstrual bleeding with no known or reversible causes.
- It can be used as an adjunct for Hormone Replacement Therapy.
- Most women can have it. There are certain conditions where the Mirena is not recommended. Please discuss this with your doctor in further detail.
- It does not matter if the woman has had children before.
- It is more effective than the oral contraceptive pill. It is 99.8% effective as compared to the oral contraceptive pill which is 91% effective for typical use.
- It is a long acting reversible contraception which lasts for 5 years. You can set and forget, without the need to remember to take a pill every day.
- It is more cost effective in the long term.
- There is minimal absorption of the progesterone hormone into the rest of the body.
- There is some discomfort associated with the insertion process.
- There are risks associated with the procedure.
- Abdominal or pelvic pain. This is usually mild and intermittent.
- Vaginal discharge.
- Side effects are most significant during the initial period after insertion, then generally improve and subside.
- It is expected within the first 3 months of insertion, that there will be more frequent bleeding, averaging 30 days in the first 3 months. This improves with time.
- 20% of women do not have menstrual bleeding after a year.
- Women who have heavy menstrual bleeding can have blood flow reduced by 90%.
- Your GP cannot accurately predict if periods will remain regular as it varies for all women.
The insertion of a Mirena can be performed by a gynaecologist or a GP with extra training. Some General Practitioners at Women’s Health Hub have had extended training and are qualified to perform the Mirena insertion.
The starting point for a patient is to book an initial extended consultation with the GP which takes around 20 minutes. The GP will discuss the alternatives with the patient to determine the health issue at hand and whether the Mirena is the best solution for the patient.
We make sure that every single woman who has the procedure provides a prior urine sample to test for chlamydia or gonorrhoea. If suitable, the GP will provide a script for to buy the Mirena at the chemist.
On the day of the procedure, patients spend an hour in clinic, which includes performing certain checks done with our nurse before and after the procedure. The actual length of procedural time is no more than 15 minutes.
We strongly recommend panadol and neurofen around 30 minutes prior to the procedure to minimise discomfort.
1 in 100 risk of infection
We minimise this risk by doing a urine test for chlamydia and gonorrhoea at the initial consultation and by performing the procedure under sterile conditions
5 in 100 risk of expulsion
In some women, the uterus contracts and expels the Mirena of its own accord. We recommend doing a monthly check for the presence of Mirena strings after insertion to minimise the chances of an undetected expulsion.
1 in 400 risk of perforation
This occurs when the Mirena device extrudes from the uterus into the abdominal cavity. Every care is made by our doctors to minimise the risk of perforation thru various methods.
As Mirena is effective at preventing 99.8% of all pregnancies. The chances are greatly reduced as compared to a woman who is not taking any form of contraception.
The Mirena device costs around $40 at the local chemist. The procedure costs $250, and around half is covered by Medicare so the out of pocket is $124.10
We require a minimum of 24 hours’ notice before the appointment time to cancel or reschedule your appointment. If you choose to cancel and enough notice has been given you will be reimbursed all but the $250. If you fail to give 24 hours’ notice there will be no money reimbursement for a cancellation.
