IUD and HRT: the underused combination
The Mirena IUD is one of the most elegant tools in perimenopause: it delivers levonorgestrel locally to the uterus, protects the endometrium during estrogen HRT, controls heavy bleeding, and provides contraception — all with minimal systemic side effects. If you have a uterus and need HRT, the IUD deserves a seat at the table.
Why the combination works
Estrogen without progestogen thickens the endometrial lining and increases uterine cancer risk. Mirena delivers levonorgestrel directly to the endometrium at concentrations 100× higher than oral dosing — with only ~10% of the systemic exposure. Endometrial protection is complete; systemic side effects are minimal.
What Kindr does
We prescribe transdermal estradiol paired with Mirena if you already have one, or coordinate with your gynecologist to place one. If Mirena isn't right for you, we prescribe micronized progesterone instead.
Frequently asked questions
Can Mirena replace oral progesterone in HRT?
Yes. NAMS and international guidelines accept Mirena as the progestogen component of HRT for endometrial protection.
How long is Mirena effective for HRT?
Up to 5 years for endometrial protection, and up to 8 years for contraception in perimenopause (guidance varies).
Fewer side effects than oral progesterone?
Often yes — local delivery means much lower systemic progestin exposure. Women who felt sedated, bloated, or moody on oral progesterone often tolerate Mirena.
Does Mirena stop periods?
For most women, yes — over half stop bleeding entirely within 12 months. That is a feature, not a bug, in perimenopause.
Who should not use Mirena?
History of hormone-sensitive cancer, active pelvic infection, or uterine anomaly. Talk to your gynecologist.
