Requires an appointment with a specialist nurse or doctor to have it fitted. It works immediately, meaning you won’t need to use any other contraception once it’s fitted.
The non-hormonal coil or IUD is a T-shaped flexible plastic device, slightly bigger than a 50p coin, that is placed in the uterus.
It prevents pregnancy by:
The IUD is a method of long-acting reversible contraception (or LARC). These methods don’t rely on you remembering to take them, but they do need a trained doctor or nurse to administer or fit them for you.
Emergency contraceptionThe non-hormonal coil can also be used as a form of emergency contraception if fitted within five days of unprotected sex. More about the non-hormonal coil as emergency contraception
As the copper coil is a non-hormonal contraceptive method, you will continue to get your period as normal. Periods can become longer, heavier or more painful during the first few months of use.While using the copper coil, your provider may recommend you don’t use menstrual cups or tampons for the first few weeks of use.
The non-hormonal coil needs to be fitted by a doctor or nurse who has been specially trained. It is available free of charge from a range of services including contraceptive clinics, your GP and Brook.
Contraception and sexual health services such as Brook are free and confidential, including for people under the age of 16. Health professionals work to strict guidelines and won’t tell anyone else about your visit unless they believe you’re at serious risk of immediate harm. Find out more about Brook’s confidentiality policy.
You will need to book an appointment at a contraceptive clinic or with your doctor. This appointment will typically include:
Some services may be able to fit it at the same appointment, or you may need a second appointment.
The doctor or nurse may discuss painkiller tablets/using local anaesthetic to make the fitting more comfortable. You can also bring someone with you for support.
Fitting the coil shouldn’t take longer than 5 minutes:
The coil fitting may be uncomfortable for some people. The doctor or nurse may discuss painkiller tablets and/or using local anaesthetic to make the fitting more comfortable. Learn more about support for survivors of sexual abuse, assault or trauma.
Most people feel well enough to leave straight after the appointment.
You may get some period-type pain and possibly some light bleeding for a few days afterwards.
The coil has two threads which hang through the opening at the entrance of your uterus (cervix). You should check the threads a few times during the first month and then at least once a month.
You will then only need to go back when the coil needs to be replaced (5 to 10 years depending on the type of non-hormonal coil).
The non-hormonal coil can be fitted at any time in your cycle if it is certain that you are not pregnant. It may also be possible to fit the copper coil as emergency contraception. Check the emergency contraception calculator to work out if it is not too late to fit a non-hormonal coil.
As soon as the non-hormonal coil is fitted then you will be protected immediately. You will be asked to take a pregnancy test before the non-hormonal coil is fitted and another three weeks later if there is a pregnancy risk.
You can get a non-hormonal coil fitted after a birth, abortion or miscarriage but when you can get it fitted does vary.
You can get pregnant from as little as three weeks after giving birth.The copper coil can sometimes be fitted 48 hours after giving birth. However, in most cases you will need to wait four weeks meaning you will need to use alternative contraception from week three (21 days) after the birth until the coil is fitted. The copper coil is safe to use whilst breastfeeding.
You can become pregnant from two weeks after an abortion or miscarriage.The copper coil can be inserted immediately after an abortion or miscarriage and you will be protected immediately from pregnancy.
Always speak to your midwife, GP or nurse at a sexual health clinic to check this is the right method for you
The coil must be removed by a trained doctor or nurse, the procedure should be less painful and quicker than having the coil fitted. If you are not going to have another coil you will need to use additional contraception, such as condoms, for the seven days before the coil is taken out if you do not want to become pregnant.
Your fertility should return to normal as soon as the coil is removed.
Some people may find the fitting painful but you can have pain relief (local anaesthetic) to help. If this is something you would like, it’s a good idea to talk to the nurse or doctor beforehand. For most people pain only lasts a couple of minutes and then you don’t have to worry about contraception for the next five to ten years!
You can get a copper coil or a hormonal coil fitted at any time during your cycle. There is no medical evidence to prove that having it fitted during your period has any additional benefits.
No. This is a common myth based on the fact that copper coils can be used as emergency contraception even if ovulation has occurred (unlike emergency contraceptive pills also known as the morning after pill). However, emergency contraception does not cause an abortion but prevents a pregnancy from taking place. In the case of the IUD, the copper in the coil kills the sperm before it reaches the egg and is fertilised.
No, the copper coil and hormonal coil are used to prevent pregnancy so should not be used if there is any chance of pregnancy as this may cause an ectopic pregnancy.
