Intrauterine System (IUS) – a small T-shaped plastic device that’s inserted into your womb (uterus). One popular brand of the IUS is the “Mirena Coil”. The IUS releases a progesterone hormone to stop you getting pregnant and lasts for 3 to 5 years. This is similar to the natural progesterone that women produce in their ovaries. There are three brands of IUS used in the UK: Mirena, Jaydess and Levosert. Learn more about IUSs here.
Intrauterine Device (IUD) – a small T-shaped plastic and copper device that’s inserted into your womb (uterus). It’s sometimes called a “copper coil”. The IUD releases copper (no hormones) to stop you getting pregnant and protects against pregnancy for between 5 and 10 years. Learn more about IUDs here.
The IUD can also be used as emergency contraception.
Both the IUS and IUS are long-acting reversible contraceptive (LARC) methods meaning that once they’re in place, you don’t have to think about it each day or each time you have sex. Once removed your fertility goes straight back to what is normal for you.
Both coils are 99% effective at preventing pregnancy – one of the most effective methods there is. Less than one IUS/IUD user in 100 will get pregnant in one year.
Once the coil is in place – you don’t need to worry about it! Just come back when your coil is ready to be renewed. The coil can be taken out at any point if you change your mind.
If you would like either the IUS or IUD coil, you MUST attend an initial consultation to ensure this method is the right one for you. After this consultation, you can be booked in for a coil fitting. Please contact your nearest Spectrum clinic for a consultation. Some GPs will also offer this service, however please check with your registered practice first.
