IUS - HormonalCoil_Long Acting

THE IUS – AKA THE
HORMONAL COIL

A small coil with local action.

WORKS FOR UP TO EIGHT YEARS

The intrauterine system (IUS) is a small, soft, T-shaped device with a reservoir containing a progestogen hormone that is placed in your womb by your doctor or nurse. It slowly releases the hormone, which thins the lining of your womb and thickens cervical mucus, making it harder for sperm to get through. There are three types of IUS with different amount of hormones. Discuss with your healthcare professional which best suits your needs.

A couple of consultations with your doctor or nurse is about all that's needed. Once you've discussed it, and decided that it's the right method for you, the IUS can be fitted. It works continuously for up to 3, 5 or 8 years with no daily or weekly routine to remember. Should you decide that you no longer want to have the IUS, it can be removed at any time by a healthcare professional, and its effects will wear off quickly, allowing you to return to your normal fertility level. As no contraception method is for everyone, it's important to discuss the hormonal coil with a healthcare pro-fessional first.

The IUS does not protect against sexually transmitted infections.

HOW IT MEASURES UP

Typical use means how well the method works in real life and perfect use means how well a method works under 'perfect' or ideal conditions for example when there is no user error at any time.

EFFICACY WITH TYPICAL USE

The IUS is more than 99% effective with “typical use” meaning that less than one woman in every 100 who uses this method for one year will become preg-nant.

The hormonal coil is a highly effective option because once it is fitted by a healthcare professional it doesn't rely on you having to remember it in order to work. Therefore, there is no difference in its typical use and perfect use effec-tiveness.

With a prescription, the IUS is inserted by a doctor or nurse and left in place for up to 3, 5 or 8 years depending on the type you choose. It is a highly effective and reliable method of contraception.

HORMONES

Yes. A progestogen hormone is released from the IUS into the womb where it acts mainly locally. There are three types of IUS with different amount of hormones. Discuss with your healthcare professional which best suits your needs. 

EASE OF USE

The IUS must be fitted by a doctor or nurse, but once it is correctly placed it is effective for up 8 years, depending on the type you select. If you want to stop using the IUS, a doctor or nurse can remove it.

YOUR PERIOD

Periods may become lighter or less frequent, with some women experiencing no periods at all. However, spotting and irregular bleeding can also be common in the first 6 months of use.
