THE IUS – AKA THE HORMONAL COIL

A small coil with local action.

WORKS FOR UP TO FIVE YEARS

the ius

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.

 

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 or 5 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 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 professional first.

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 PERFECT USE

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

EFFICACY WITH TYPICAL USE

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. This is why there is no difference in its typical use and perfect use effectiveness.

Hormones

Yes. A progestogen hormone is released from the IUS into the womb and acts mainly locally.

Ease of Use

The IUS must be fitted by a doctor or nurse, but once it is correctly placed it is effective for up to 3 or 5 years. If you want to stop using the IUS, a doctor or nurse can remove it.

Your Period

Periods may become lighter or less frequent. However some women experience cramps and irregular bleeding. Spotting is also common in the first 6 months of use.
