You encounter a 55-year-old woman who is currently on estrogen-only hormone-replacement therapy (HRT) and has a Mirena® levonorgestrel intrauterine system (LNG-IUS) for endometrial protection (not contraception). She has been following this HRT regimen for the past 3 years. She is curious about when she should consider replacing her Mirena®. What guidance should you provide to this patient?
