Coils – Patient Information and Questionnaire

Preparation for insertion of a coil

This leaflet is to help you prepare for the insertion of a copper coil (IUD/Intrauterine Device”) or hormone coil (IUS/Intrauterine System).  To make your visit as straightforward as possible and to ensure that the procedure takes place, it is important that you read all the information before attending your appointment. 

You should have already been given a prescription for your preferred coil.  You must collect this from the pharmacy and bring it with you to the appointment.  Please also bring this completed questionnaire with you when you attend the clinic or send it to us in advance.

General Information

Your coil fitting or replacement appointment will last around 30 minutes.

There are no crèche or child-minding facilities at the clinic and we will not be able to fit a coil if you bring a dependent child to your appointment.

The procedure is usually very quick but can be uncomfortable or even painful, especially in women who have never given birth. Some women feel dizzy or sick during or after the procedure but you should have had a light meal on the day of the appointment.

Simple painkillers like Paracetamol and/or Ibuprofen could also be taken around an hour before the procedure.

If you are taking certain medicines (e.g. drugs which lower your blood pressure or help with anxiety such as propanolol) please take them after the coil insertion. Please contact us if you have any questions about this.

You may not feel ready to drive home after the procedure because of pelvic pain, dizziness or nausea. You should consider a backup plan for someone to take you home, especially if you are travelling some distance. For the same reason, you might not be able to go back to work or to look after somebody else straight after the procedure.

Please bring a urine sample with you as a pregnancy test may be required.

If you are unable to make it to your appointment please let us know as soon as possible so that we can use it for someone else.


Please tick the boxes to confirm that you have understood and agreed to the following:

 I have watched the video on coils (IUD- copper coil or IUS- hormone coil), read the Family Planning Association (FPA) IUD and/or IUS leaflet I already have a coil and I am familiar with the method.
 I am using an effective method of contraception and haven’t had any problems recently (for example missed pill, slipped condom, late contraceptive injection or expired coil or implant) or I have not had unprotected sex since my last natural period or used the withdrawal method. I understand that it is not safe to insert a coil if I might be pregnant. A pregnancy can only be excluded three weeks after the last unprotected sexual intercourse.
 If I am having my coil changed I understand that it is important to abstain from sex for the seven days before my appointment or consistently use condoms during this time.
 If I am under 25, have had a new partner or more than one partner in the last 12 months, I have taken a recent test for chlamydia and gonorrhoea which came back negative or will be offered a test at the coil fitting. If I have symptoms of infection like pelvic pain and/or vaginal discharge, it is likely that my coil fit will be postponed.
 I understand that if I am having period problems (for example irregular, unusual bleeding or heavy periods) or have been diagnosed with fibroids or have a complicated medical history my coil fitting may be postponed for further investigations and/or a coil might not be a suitable option for me.
 I understand that no method is 100% effective and that the coil has a very small risk of failure (less than 1 in 100 chance of pregnancy).
 I understand that if I do become pregnant with a coil in place, there is an increased chance of an ectopic pregnancy (outside the womb). The overall risk of pregnancy is still very small.
 I understand that there is a 1 in 20 chance of the device falling out, partially or completely, especially in the first months after insertion.
 I understand that there is a 2 in 1000 risk of going into or through the wall of my womb (perforation) at the time of insertion of the device which might require keyhole surgery. I understand that the coil will not protect me against sexually transmitted infections (STIs).
 I understand that a copper coil can make my periods slightly heavier, longer and more painful.  
 I understand that a hormone coil can make my periods much lighter or stop them altogether but can also cause erratic bleeding and spotting, especially in the first few months of use.
