Mirena will still be OK at this stage for contraception but it can only be used for the progestogen part of HRT for 5 years, it can not be relied on after that to provide enough progestogen to protect the womb lining from being stimulated by the estrogen. Therefore, either the Mirena should be changed for a new Mirena and continue estrogen only HRT, or the HRT should contain both estrogen and progestogen.
I hope this is helpful
This is an important point. Would anyone mind if we include a version of this in the next issue of Menopause Matters magazine?
Best wishes
