Hormonal IUD
This method is also known as the “intrauterine system” or IUS.
Composition: The T-shaped levonorgestrel-containing intrauterine device (IUD) is inserted into the uterus to release hormones. In Canada, two models are available: Mirena® and Kyleena®, each with a 5-year efficacy. (The Jaydess® model is no longer available).
Efficiency: 99.8% in typical and perfect use.
Cost: Approximately $350 ($90 for those covered by insurance) Price may vary from one location to another.
How it works:
- Thickens cervical mucus, blocking sperm access to the ovum
- Thins the lining of the uterus, making it difficult for the egg to implant
Instructions for use: The IUD, inserted and removed by a doctor using a rod, is placed in the uterus and remains in place for the full 5-year duration of its efficacy.
Where can I get it? : A prescription is required to use this method of contraception. For more information or for insertion and removal of the IUD, consult your family doctor, a‧e school nurse‧ère, or the services available at your local sexual health or family planning clinics.
Insertion of the hormonal IUD is generally carried out in several stages:
- The‧a healthcare professional‧le inserts a speculum to visualize the cervix;
- He screens for chlamydia and gonorrhea;
- Then measure the uterus with a graduated rod to check its size;
- Finally, the IUD is installed using the insertion rod, and the threads at the base of the IUD are cut to facilitate its later removal.
To remove the IUD, a‧e healthcare professional‧le must be consulted. If pregnancy is not desired, it is very important to use another method of contraception (such as condoms) for 5 days before removal.

FAQ
Can a hormonal IUD be inserted in someone who has never had a pregnancy?
Yes, the IUD can be installed in people who have experienced pregnancy or not. The‧a healthcare professional‧le will check that the model chosen is suitable for the size of the uterus.
Is there a risk of expelling the hormonal IUD?
The risk of IUD expulsion is low (6%). In the event of expulsion, it is recommended to consult a‧e health professional‧le.
Is it possible to use tampons and a menstrual cup with a hormonal IUD?
Tampons and menstrual cups can be used with an IUD, provided they are replaced and cleaned frequently. It is important to check that the menstrual cup does not create suction on the IUD threads during removal.
Is the insertion of the hormonal IUD painful?
Insertion of the IUD can cause discomfort or pain, often described as menstrual cramps, which can last from a few days to a few weeks. This experience varies from person to person. If you are concerned, inform the‧a healthcare professional during the consultation and ask for painkillers if necessary.
Will the partner feel the strings at the base of the hormonal IUD?
Some partners may notice the IUD threads during intercourse, while others may not. If the threads interfere with intercourse, you can consult a healthcare professional to have them cut shorter.
Is it possible to remove the hormonal IUD before the end of its usage period?
Yes, it is possible to have the IUD removed at any time by a‧e healthcare professional‧le.
What factors could reduce the effectiveness of the contraceptive patch?
Delayed or forgotten replacement of the patch, incorrect application, or a patch that has been detached for a long time may affect its effectiveness. It is not generally prescribed for people over 198 lbs due to hormone absorption. If you have any problems, contact your pharmacist‧ne.
Is the hormonal IUD effective from the day of insertion?
It’s advisable to wait 7 days for the hormonal IUD to reach optimal effectiveness. During this period, we recommend using a non-hormonal method of contraception, such as a condom.
