Mirena and Copper IUDs: 8 Questions Hervey Bay Women Ask

An IUD is a small device placed in the uterus that provides contraception for between five and ten years, depending on the type, and can be removed at any time. It is one of the more reliable contraceptive options available, and it does not rely on remembering a daily pill. Below are eight questions women commonly ask before booking, answered plainly.

At Main Street Medical Centre in Pialba, IUD insertions are performed by Dr Padma Kaki (FRACGP, DRANZCOG) as part of our women’s health services.

1. What is the difference between a hormonal IUD and a copper IUD?

There are two broad types available in Australia.

• Hormonal IUDs (such as Mirena and Kyleena) release a small amount of levonorgestrel directly into the uterus. They typically make periods lighter, and some women stop having periods altogether. Mirena is approved for up to eight years of contraception in Australia, extended from five years, and Kyleena lasts up to five years.
• Copper IUDs contain no hormones and work by making the uterus inhospitable to sperm. Depending on the device, they last between five and ten years. Periods often become heavier or crampier, particularly in the first few months.

Which suits you depends on your cycle, whether you want hormone-free contraception, and your medical history. Your GP will talk this through with you at the first appointment.

2. How effective is an IUD?

Both types are more than 99 per cent effective at preventing pregnancy. Because there is nothing to remember daily, real-world effectiveness stays close to that figure, which is not the case for the pill.

3. Does having an IUD inserted hurt?

Most women feel cramping during insertion, similar to strong period pain, which usually settles within a few minutes to a few hours. Some feel very little. Discomfort varies a good deal between individuals, and it is often reported as less difficult than anticipated.

You can take simple pain relief such as ibuprofen an hour beforehand. Talk to your doctor in advance if you are anxious about pain, as there are options to make the procedure more comfortable, and it is a reasonable thing to raise.

4. How long does the appointment take?

The insertion itself usually takes five to ten minutes. The appointment is longer, because it includes checking your history, a pregnancy test if needed, and time to rest afterwards. Expect to be at the clinic for around 30 to 45 minutes.

Most women have two appointments: an initial consultation to discuss options and plan timing, then the insertion itself.

5. When in my cycle can it be inserted?

An IUD can be inserted at most points in the cycle, provided pregnancy has been excluded. Many doctors prefer during or shortly after a period, when the cervix is naturally a little softer and pregnancy is unlikely. Your GP will advise on timing and whether you need additional contraception in the first week.

6. What are the side effects and risks?

Common and expected effects include irregular spotting for the first three to six months as your body adjusts, cramping in the first few days, and a change in bleeding pattern that differs by IUD type.

Less common risks include the device moving out of position or being expelled, which is why a follow-up check matters, and infection in the first few weeks. Perforation of the uterus is rare. Your doctor will go through these with you and give you the signs to watch for.

See a doctor if you develop fever, severe abdominal pain, unusual discharge, or if you cannot feel the threads.

7. Can I have an IUD if I have not had children?

Yes. IUDs are suitable for women who have not been pregnant, and smaller devices such as Kyleena are often chosen in this situation. Insertion can be slightly more uncomfortable, which is worth discussing beforehand.

8. What does an IUD cost in Hervey Bay?

At Main Street Medical Centre, bulk billing is available for eligible patients with a valid Medicare card. The device itself is dispensed on prescription through a pharmacy, and hormonal IUDs are subsidised under the PBS, so the cost to you is usually modest. Patients without Medicare pay the standard $89 consultation fee.

Common questions

How soon does an IUD start working?

A copper IUD works immediately. A hormonal IUD works immediately if inserted in the first seven days of your cycle; otherwise use additional contraception for seven days. Your doctor will confirm which applies to you.

Can an IUD be removed early?

Yes. An IUD can be removed at any time by a GP, and fertility returns quickly afterwards. Removal is usually quicker and more comfortable than insertion.

Will my partner feel it?

The device sits inside the uterus and should not be felt. Two fine threads sit in the upper vagina and soften over time. If threads are causing discomfort, your GP can trim them.

Do I need a check-up after insertion?

A follow-up around six weeks after insertion is usual, to confirm the device is correctly positioned and answer any questions. After that, yearly checks are generally enough.

Can I use tampons or a menstrual cup with an IUD?

Tampons are fine. Menstrual cups can be used, but take care to break the seal before removing the cup, as suction has occasionally been linked to displacement.

Does an IUD protect against sexually transmitted infections?

No. An IUD prevents pregnancy but offers no protection against STIs. Condoms remain necessary for that.

If you are also wondering what other checks are due at your stage of life, our guide to women’s health checks by age sets out what is generally recommended in your 20s, 30s, 40s and beyond.
