The hormonal IUD

What is the hormonal IUD?

The hormonal IUD (also known as the Mirena or Kyleena) is a soft T-shaped, plastic device that is inserted into the womb by a healthcare provider to prevent pregnancy. It is smaller than the palm of your hand. It continuously releases small amounts of a hormone called levonorgestrel which is similar to progestogen. 

When used correctly, the hormonal IUD has a very high chance of preventing pregnancy. The hormonal IUD does not prevent STIs and HIV but a male/external or female/internal condom can.

How does the hormonal IUD work?

The hormonal IUD works like other hormonal contraceptives to prevent pregnancy. This means that the progestin hormone in it stops the ovaries from releasing eggs. The hormonal IUD also changes the lining of your womb and cervix to stop sperm from reaching the egg.

How often do you use the hormonal IUD?

Hormonal IUD brands like the Mirena or Kyleena are effective for five years.

  • Mild and treatable side-effects from the hormonal IUD sometimes occur like irregular or heavier periods, acne, abdominal pain, mood changes and vaginal discharge. 
  • If you feel like the hormonal IUD is no longer in the correct place, is slipping out or you can feel the strings attached to it please ask your healthcare provider to check if it is in the correct position.

How do I get additional protection against HIV and STIs when using the hormonal IUD?

For additional protection against HIV and STIs, different prevention options can be explored, such as PrEP and using a condom. Using condoms and contraception together is what we call “dual protection”.
