This information explains all about the IUD.
The Copper coil – long acting, reversible and reliable contraception.
Information for patients
The IUD is a small T-shaped plastic and copper device which is put into your womb.
The main way it works is to stop sperm reaching the egg. It may also stop a fertilized egg from settling in the womb.
The failure rates for IUD are less than 1% per year.
If you are at risk of STls then you may be more at risk of getting a pelvic infection - this is more likely in the first 3-6 weeks after the IUD is fitted. To try to prevent this happening we offer a test for Chlamydia and Gonorrhoea to all women prior to the fitting.
Occasionally, a women’s body might push the IUD out of her womb (expulsion); this is more likely to happen in the first few months after fitting.
On rare occasions the IUD may go through (perforate) your womb or cervix. Sometimes this causes pain but it may cause no symptoms at all. If this happens then the IUD may have to be removed by surgery.
If you do become pregnant while you are using an IUD there is a small risk that the pregnancy may be an ectopic pregnancy. However, the risk of an ectopic pregnancy is less in women using an IUD than in women using no contraception.
Ask the nurse or doctor in clinic and they will talk to you about the advantages and disadvantages of having an IUD and they will offer you a test for Chlamydia and Gonorrhoea.
An IUD is fitted inside the uterus (womb). The nurse or doctor will examine you internally to check the size of your womb before they fit the IUD. The fitting usually takes between 15 to 20 minutes.
On the day of your fitting appointment please have something to eat and one hour before take a dose of a mild painkiller (paracetamol or ibuprofen).
After the fitting you may get some period type pain and some light bleeding for a few days. It is a good idea to take a mild painkiller (paracetamol or ibuprofen) to help with this.
If you have any problems or feel unwell (with pain or discharge from your vagina) then please seek medical attention.
Each IUD has one or two threads attached to it, which hang through the neck of the womb (cervix) into the vagina. You can check that your IUD is in the right position by putting a finger in the vagina to feel the IUD threads coming out of the cervix. You should not be able to feel the IUD itself. It is advisable to check your IUD in this way once a month ideally just after your period finishes.
An IUD is usually fitted from 4 weeks after vaginal or caesarean delivery. The IUD is safe to use whilst breastfeeding.
Your periods may become longer or heavier and you may have spotting (light bleeding between periods) in the first ,6 months after an IUD is fitted. It is safe to use tampons with an IUD.
If you have heavy or long periods you may wish to consider a hormone releasing IUS (called an intrauterine system e.g. Mirena, Levosert or Kyleena).
An IUD can be removed at any time by a trained nurse or doctor. If you do not want become pregnant you need to start using alternative method of contraception 7 days before you have your IUD removed, ask the clinic nurse or doctor for advice about this.
No. if you have no problems, and you can feel your IUD threads, then you do not need to have regular IUD checks.
If you have any of the following problems then please attend our clinic, your GP or Rotherham Urgent and Emergency Care Centre for an urgent appointment.
An IUD is extremely effective as emergency contraception if it is fitted within 5 days of having sex or within 5 days of the expected release of an egg (ovulation).
No, the IUD only protects you from pregnancy. If you want to avoid STls including chlamydia, gonorrhoea and HIV, it is important to use condoms as well.
Condoms are available free from clinic.
This information should not replace the information that accompanies your IUD which will be given to you after the fitting.
Sometimes there may be a trainee doctor or nurse in clinic, fitting your IUD. All trainees are closely supervised by experienced doctors.
Please make an appointment for one of our clinics.
