The Mirena intra-uterine contraceptive device is a long-acting acting reversible contraception. With an average efficacy rate of 99%, Mirena is considered one of the most effective methods of contraception that does not require further interventions such as daily dosing or monthly administration, with the option of removal at any time.

The Therapeutic Goods Administration (TGA) of Australia revised its recommendation for the length of use of the Mirena in 2024, and the current advice is summarised below:

• If used only for contraception, The Mirena can be retained for 8 years after which it needs to be removed or replaced.

• If used for heavy menstrual bleeding, and if symptoms have not returned after 5 years of use, continued use of the system may be considered up to 8 years.

• If used for protection from endometrial hyperplasia during estrogen replacement therapy (as part of Hormone Replacement Therapy or HRT / Menopausal Hormone Therapy or MHT), the Mirena should be replaced after 5 years.

If you are almost due or due for removal and replacement of your Mirena, Dr Nitin Trasi can assist you in deciding if keeping the Mirena in for longer than 5 years is good for you.
