You’d like to start taking estrogen to treat perimenopause — but you aren’t ready to have your intrauterine device (IUD) removed. If this sounds familiar, you’re not alone. You may be noticing perimenopause symptoms while still wanting to prevent pregnancy.
Can you use both an IUD and estrogen therapy at the same time for perimenopause? Keep reading to find out the answer.
Two main types of IUDs are used for contraception. Nonhormonal IUDs don’t contain hormones and are sometimes called copper IUDs. Paragard is the only nonhormonal IUD available in the U.S.
Hormonal IUDs release levonorgestrel. Levonorgestrel can help lighten, stop, or change the frequency of your menstrual cycles. It’s used for birth control and may also be used as part of perimenopause care.
Hormonal IUDs in the U.S. are sold under brand names including Mirena, Liletta, Kyleena, and Skyla.
Women who still have a uterus generally shouldn’t use systemic estrogen therapy alone. Instead, they’re typically advised to use estrogen with progesterone or a progestin.
Adding progesterone or a progestin to your hormone therapy regimen helps reduce your endometrial cancer risk. This is also referred to as endometrial protection.
To meet this need, many women take progesterone pills while using estrogen therapy. But levonorgestrel delivered through certain hormonal IUDs may be an alternative for providing endometrial protection in some women using hormone therapy.
This is considered an off-label use of a hormonal IUD in the U.S. because hormonal IUDs aren’t FDA-approved to provide endometrial protection as part of hormone replacement therapy.
There are several potential benefits of using a hormonal IUD alongside estrogen, as well as some considerations when choosing what’s best for you.
Some hormonal IUDs can be used for contraception for up to eight years without having to be removed or replaced. But if you’re using a hormonal IUD as part of your combination hormone therapy regimen, that timing could differ.
Researchers aren’t sure whether a hormonal IUD can provide endometrial protection when used with estrogen therapy for more than five years. More studies are needed to determine how long that protection lasts.
Ask your menopause care team whether it’s safe for you to use an IUD with estrogen therapy. They can weigh the decision against your overall health, other medications you’re taking, and your menopause treatment goals.
