The license for Mirena intrauterine system for contraception only has been increased from five years to eight years from the date of insertion.

This change came into effect on Friday 12th January 2024 and is for Mirena only and not for other hormone containing devices such as Kyleena, Levosert and Benilexa.

The extension in license is also only when the Mirena is used for contraception. If a patient is using the mirena coil for HRT purposes, guidance remains the same and it should be replaced after five years of use.   

What does this mean if you are using Mirena?

• If you are getting a Mirena inserted from now, you will be advised it can be used for eight years to provide contraceptive protection.
• If you are already using a Mirena you can continue with your current device for eight years to prevent pregnancy.
• If you are aged 45 years or over at the time of insertion and using it only for contraception you will continue to be advised it can be used for 10 years or to age 55 (outside of the license).

EXAMPLE: A Mirena inserted on 5th June 2020 can be continued and will provide contraception until 5th Jun 2028.
