Levonorgestrel intrauterine system (IUS) is used to prevent pregnancy. It is also used to treat heavy bleeding or endometriosis.
Levonorgestrel IUS is inserted into your uterus by a health professional.
Your IUS can stay in place for 3 years (Jaydess®) or 5 years (Mirena®).
Visit the Family Planning website for more information:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products or recreational drugs.
Some women have period-like cramps or feel faint when their IUS is inserted. Taking paracetamol or ibuprofen and having something to eat before your appointment may help prevent this. You may also want to have someone to drive you home, and to be able to rest for a while afterwards.
