Hormonal Coils
The Mirena IUS (intrauterine system), also known as a hormonal coil, is used by many of our patients.
We want to share some important updates regarding its use. Since 2024, the licence for the Mirena IUS has been extended:
- Contraception: If you had the Mirena fitted before age 45, it can now remain in place for up to 8 years. If you had it fitted at age 45 or older, you can keep it until age 55.
- HRT (Hormone Replacement Therapy): If you’re using the Mirena for HRT, it can still be used for up to 5 years.
When you had your coil fitted, you should have been provided with information on when to replace it. If you are unsure about this, please contact us using the form below.
