Mirena LNG-IUD coils, inserted for contraception, can now be retained and used for contraception for 8 years

Recent guidance from the FSRH has now changed. Mirena LNG-IUD coils, inserted for contraception, can now be retained and used for contraception for 8 years. This was previously 6 years. Levosert and Benilexa LNG-IUD coils currently remain at 6 years. If you are using a Mirena, Levosert or Benilexa LNG-IUD coil as part of HRT, this remains at 5 years and should be changed at that point.

What is Intrauterine Contraception?

There are two types of intrauterine contraception which we can fit, a hormonal (IUS) and non-hormonal option (IUD). Both are often referred to as 'coils'.

A coil is a very effective (8 in 1000 failure rate) reversible method of contraception, which can last for 6-10 years depending on the type. It is a small, T-shaped plastic device that is inserted into your womb (uterus) by a trained specialist. Once the coil is in fitted you do not have to think about it each day or each time you have sex.

At the clinic we will discuss your options with you and check that a coil is a suitable method of contraception for you.

NHS Greater Glasgow and Clyde only

Please note we can only offer appointments to residents of NHS Greater Glasgow and Clyde Health Board area.

Important information on Coil Insertion

It is essential that you read all of the information on this page before attending for your appointment so that we are able to fit your coil safely.

Please remember:

To have protected sex after your last period until your coil is fitted.
This means using condoms consistently and correctly, or using another form of reliable hormonal contraception such as the combined pill, patch or ring, progestogen-only pill, injection or implant.
If you are not having regular periods you should use effective contraception or avoid sex for at least 3 weeks before having your coil fitted.

Attending Clinic with Children

Children will not always be allowed into your appointment with you. This is because it is not always safe to have children in the clinical room. You are welcome to bring an adult with you, to Sandyford to look after your children when you attend your appointment, as we do not have childcare facilities available. If you do bring children with you without another adult, the clinician may decide the procedure needs to be rearranged.

What will happen at my appointment?

After checking in at reception, you will be called into the clinic by a doctor or nurse. They will talk to you about the options and check this is a suitable method of contraception for you. They will ask you about any illnesses or operations you or your family may have had. They will also discuss sexual health and cervical screening with you.

If suitable they will be able to fit your coil for you during the appointment. The appointment generally lasts for 30 minutes.

Information on the procedure

At your coil appointment, you will be having a procedure and some people may feel a little faint or unwell.

Please ensure you have a light meal before attending your appointment.

Some people experience cramping after the procedure. It may be helpful to take some simple painkillers before attending your appointment.

Emergency Contraception

The non-hormonal intrauterine device (copper coil) can be used as a form of emergency contraception. If you think that you need emergency contraception please contact us as soon as possible by phoning: 0141 211 8130.

After you've had a coil fitted

After you've had hormonal or non-hormonal coil fitted the doctor or nurse who fitted your coil will teach you how to feel for the threads and check that it's still in place. It's important to check your coil is in place a few times in the first month, and then after each period or at regular intervals.

It's highly unlikely that your coil will come out, but if you can't feel the threads or if you think the coil has moved, you may not be fully protected against pregnancy.

Call Sandyford straight away on 0141 211 8130 if you think your coil has moved, fallen out or you have pain or bleeding.

Use extra contraception, such as condoms, until your coil has been checked.

If you've had sex recently, you may need to use emergency contraception.

FAQs for Coils

My hormonal coil (IUS) has now expired and is due for a change. Will it still protect me?

If you are using an intrauterine hormonal coil (IUS) from the UK, it is likely to be either MirenaTM, LevosertTM or ...

If you are using an intrauterine hormonal coil (IUS) from the UK, it is likely to be either MirenaTM, LevosertTM or or BenilexaTM.

LevosertTM or BenilexaTM are now licensed for 6 years of use, and Mirena has now been licensed for 8 years for contraception use.

Please remember that if you are using any of these coils as part of HRT, then they should be changed after 5 years.

Low dose hormone coils eg Kyleena TM or Jaydess TM are not suitable for use as part of HRT.

Do older women using the intrauterine hormonal coil (IUS) need to have their device changed after 45?

People who are more than 45 when they have the MirenaTM or LevosertTM or BenilexaTM inserted can use the device for c...

People who are more than 45 when they have the MirenaTM or LevosertTM or BenilexaTM inserted can use the device for contraception until the age of 55 as it will continue to provide protection against pregnancy.

After this age, contraception is no longer needed. People who are using the Mirena, Levosert or Benilexa as part of their HRT taken with oestrogen, still need to change the coil after 5 years.

However, for those using the lower dose or shorter use hormonal coils (eg KyleenaTM, JaydessTM) it is not currently recommended that you extend the use of these products. This is because there is not enough research to say how long they will continue to work well. If you have one of these devices you are advised to use additional contraception if it has reached its expiry date.

My copper intrauterine device has expired and is now due for a change. Will it still protect me?

10 year device

Any 10 year copper coil needs replaced after 10 years, unless inserted after the age of 40 years. If inserted after 40 years, this can be used as contraception til age 55 years.

The risk of pregnancy remains extremely low, although full protection cannot be guaranteed. Some people may therefore choose to use additional precautions after 10 years have passed.

5 year device

5 year copper intrauterine devices should not be assumed to be effective after the 5 years has passed.

Is it safe to leave my coil in place after it has expired?

It is safe for your expired device to be left until you are able to get into services again. The only risk is of an unintended pregnancy so make sure you use additional precautions such as condoms or contraceptive pills to provide protection.

I was advised to extend using my hormonal coil. I wasn’t having periods before, and now they have come back. Does this mean my hormonal coil has stopped working?

It is not uncommon for your bleeding pattern to gradually change towards the end of the lifespan of the device.

If your bleeding pattern changes very suddenly with the hormonal coil, check that your coil is still in place by checking for threads.

Lots of users have sporadic bleeding when using implant or hormonal coil, however if this is unusual for you and you are beyond your replacement date it is recommended to use additional contraception such as condoms, or have a chat with your prescriber about adding hormonal contraception. Although in the first year after change date of implant and hormonal coils it is highly unlikely you will get pregnant, it is not guaranteed. Organising additional contraception can usually be done remotely via your usual provider.

I don’t have periods with my hormonal coil so how will I know whether or not I am pregnant once it is beyond the usual replacement date?

Extended use within guidelines makes the likelihood of pregnancy very low but there is still a risk. That’s why the a...

Extended use within guidelines makes the likelihood of pregnancy very low but there is still a risk. That’s why the advice is to either use condoms or if suitable another hormonal method until you can have your hormonal coil replaced. If you think you might be pregnant you should take a test 3 weeks after any risk and use condoms until you are sure.

If you are worried the coil might have fallen out and are unable to find your threads then you should also use condoms until you are able to get it checked. Organising additional contraception can usually be done remotely via your usual provider.
