Is Vaginal Estrogen Safe? What The Science Says.
Jun 26, 2023 / Updated Mar 24, 2026
Like most things related to menopause, hormone therapy (formerly known as hormone replacement therapy, or HRT) isn’t one size fits all. There are multiple types, which can be broken down into categories based on origin, composition, type of manufacturing, and whether they affect the whole body or are active locally.
We’re breaking down what you need to know about the safety of vaginal estrogen therapy.
First things first: what is vaginal estrogen?
Vaginal estrogen is a form of local hormone therapy which, as the name suggests, acts only on a specific part of the body. Topical, also referred to as local hormones are applied directly to the vagina and sometimes the vulva or vestibule (entrance to the vagina) with a low-dose estrogen or occasionally DHEA (a hormone produced naturally in the adrenal glands that’s converted by the body intro estrogen). It works by helping to maintain the structure and function of the vulvar and vaginal tissue as well as the vaginal microbiome.
What is vaginal estrogen used to treat?
Local vaginal estrogen application is an effective treatment for genitourinary syndrome of menopause (GSM), an umbrella term that encompasses various urinary, vulvar, and vaginal symptoms that occur during menopause as a result of decreasing estrogen levels. Local vaginal estrogen has been shown time and time again to be beneficial for:
- Vaginal dryness or “vaginal atrophy” in science speak
- Pain during intercourse for postmenopausal women
- Bladder health by decreasing frequent urinary tract infections (UTIs) and urinary urgency
Is vaginal estrogen safe?
Unlike systemic estrogen, which is absorbed throughout the body to treat things like hot flashes/night sweats, local options don’t carry the same risks since they only work on the tissues you apply them to, and don’t go through the bloodstream elsewhere in the body. This is why vaginal estrogen estrogen is considered safe for most, if not all women.
What if I’m a breast cancer survivor or at a higher risk of breast cancer?
Vaginal estrogen is still considered safe for you, although as with any medication, it’s recommended to seek personalized medical advice from your healthcare provider (oncologist and/or gynecologist). The same goes for cervical, ovarian, and endometrial cancer.
Until recently, there was an FDA black box warning that claimed vaginal estrogen was associated with an increased risk of stroke, heart attack, and dementia, and that it requires an opposing estrogen –– despite the fact that these risks do not apply to local estrogen. After years of advocacy for the removal of this warning by women’s health providers, as well as ACOG, the warning has finally been removed.
What if I’ve had a hysterectomy?
Women who have had hysterectomies are excellent candidates for vaginal estradiol, especially if they have had their ovaries removed as well. Estradiol helps to support the production of collagen and elastin in the walls of the vagina, which can be beneficial for structural support after a surgical procedure to remove the uterus.

What if I’m on systemic hormone therapy?
If you’re on another form of hormone therapy, you can still use local estrogen to treat vaginal symptoms, especially if you’re on a very low dose.
What if I have a history of blood clots?
Since vaginal estradiol works locally, it does not raise blood levels of the hormones and, for this reason, is very safe to use in women with a history of blood clots (DVTs/PEs) or a history of a blood clotting disorder.
What are my options?
There are many, including vaginal estrogen creams, moisturizers, tablets, inserts, and suppositories:
- Vaginal tablets: Vagifem, Vuvafem, Yuvafem
- Vaginal inserts: Imvexxy
- Vaginal creams: Estrace, Premarin, Estradiol from Odela
- Vaginal rings: Estring (not to be confused with Femring, which is systemic)
- Vaginal suppositories: Intrarosa (the only non-estrogen option)
Key takeaways
Vaginal estrogen is an effective treatment option for vaginal symptoms of menopause and it’s still considered safe for women with a history of or at high risk of breast cancer.
