HHS has announced changes to estrogen hormone therapy black box labeling for menopause treatment in a move that it said corrects misleading warnings.
HHS Secretary Robert F. Kennedy Jr. said in a press conference on Monday that women have been “told to fear the very therapy that could have given them strength, peace and dignity through one of life’s most difficult transitions, menopause,” but “that ends today.”
“We’re challenging outdated thinking and recommitting to evidence-based medicine that empowers rather than restricts,” he added. “When prescribed responsibly and started early, hormone replacement therapy transforms the lives of women.”
The details
The role estrogen replacement should play in menopause treatment has long been controversial. Concerns about menopausal hormonal therapy stem back to the publication of findings from the Women’s Health Initiative in JAMA in 2002.
The study found women receiving estrogen plus progestin had a significantly increased risk for total CVD, stroke and pulmonary embolism, and a nominally increased risk for breast cancer. The trial was stopped early due to “health risks that exceeded health benefits over an average follow-up of 5.2 years,” and its results led to a large decrease in the use of hormone therapy among women.
In July, the FDA convened an expert panel to discuss the safety and efficacy of menopausal hormone therapy, and some members stated the boxed warning should be changed to better reflect the published evidence. In the press conference, FDA commissioner Martin A. Makary, MD, MPH, said the move is based on “a robust review of the latest scientific evidence” and the July panel.
“After 23 years of dogma, the FDA today is announcing that we are going to stop the fear machine steering women away from this life-changing, even life-saving, treatment,” Makary said. “We are also approving two new drugs for the treatment of menopausal symptoms. We are listening to doctors who have been waving the flag in the air saying, ‘Hey, we have this wrong.’”

In a viewpoint published today in JAMA, Makary and colleagues wrote that the revisions to the labels “signal a meaningful shift toward more nuanced, evidence-based communication of hormone therapy risks — one that prioritizes clinical relevance, distinguishes between different formulations and patient populations, and balances the narrative to reflect both safety and therapeutic value.”
According to the viewpoint, the label updates specifically include:
- removing boxed warnings for CVD, breast cancer, probable dementia and stroke, but not the warning in systemic estrogen labels for endometrial cancer with unopposed estrogen, since “it is important to remind health care practitioners and patients that this serious risk can be mitigated by adding a progestogen”;
- removing the recommendation that hormone therapy be prescribed at the lowest effective dose for the shortest possible duration, since “treatment decisions are individualized and fall within the clinical judgment of a clinician in discussion with a patient”;
- updating timing information to include new guidance on treating women aged younger than 60 years or within 10 years of menopause onset “to optimize the benefit-risk balance”; and
- tailoring safety information that reflects the risks most relevant to each specific type of hormone therapy product.

According to Makary and colleagues, current evidence suggests that starting hormone therapy within 10 years of perimenopause onset has long-term health benefits. It has been associated with a reduced risk for fatal cardiovascular events, bone fractures cognitive decline and Alzheimer’s disease, they wrote.
Expert insight
In a statement, Steven J. Fleischman, MD, MBA, FACOG, ACOG president, commended HHS, saying “the modifications to certain warning labels for estrogen products are years in the making, reflecting the dedicated advocacy of physicians and patients across the country.”

The Menopause Society also released a statement saying it agrees with the decision since “the boxed warning may have been a deterrent to the use of the low-dose vaginal estrogen, which is a safe and effective therapy for a condition that affects most menopausal women.”
“However, systemic estrogen still comes with potential risks that should be reviewed in detail with women initiating therapy,” the organization said. “Risks are greater when initiated in older women and in those who are further from menopause onset. Medical comorbidities, personal and family histories, symptoms, and personal preferences all need to be considered and reviewed with patients considering the use of hormone therapy for management of menopause symptoms or prevention of bone loss.”
Diana Zuckerman, PhD, the president of National Center for Health Research, told Healio that “the warnings on hormone products for menopause had become outdated and it was time to update them.”
“However, these products still have clear risks, and the benefits are mostly for hot flashes and related symptoms,” Zuckerman said. “They are not the fountain of youth that some people claim, they absolutely are not proven to prevent dementia, and they are definitely not safe for everyone.”
Barbara DePree, MD, NCMP, MMM, director of the Women’s Midlife Services at Holland Hospital in Michigan, told Healio that the decision will likely increase hormone therapy uptake, which is “a win.” Yet she wondered how exactly HHS will tailor the safety information to reflect the most relevant risks for each type of hormone therapy.
“I’m not opposed to that, I’m just curious what data they’ll be using to tailor that information,” she said. “When the FDA panel happened, it felt like some of the benefits were cherry-picked from data.”
DePree was also concerned about claims that hormone therapy can prevent some very serious noncommunicable diseases.
“I’m fine with maybe taking some of the blinking red lights out of it. That gives women some more ease,” she said. “But I also think we’re not in a position to promote its use to prevent some conditions that we just don’t have the data to support, and I’m worried that it’s headed in that direction. With social media and what’s being overstated, I think this will maybe be another step in that direction, which is a little concerning.”
But she said this will likely give providers more confidence in offering the therapy as a safe alternative.
“We’ve had a whole generation of providers who’ve only grown up with data from the WHI, which basically put it completely in a risk category, and I think this brings it back to the middle for those people who’ve not really had the confidence or the understanding to properly screen women who can very safely and appropriately be using hormone therapy,” De Pree said. “We just don’t want it to say it’s the right option for every woman or just because it’s available everybody should do it because we’re going to save brains and hearts because I just don’t think we have the data to support that.”
Nanette Santoro, MD, professor and the E. Stewart Taylor Chair of OB/GYN at the University of Colorado School of Medicine told Healio that the changes “are a positive step for menopausal women and their physicians,” but was “a bit surprised the black box was completely removed.”
“The changes reflect current data, and it’s great that the route and types of hormones will be dealt with separately as the risks and benefits of estrogen alone compared to estrogen plus progestin are different. These changes should reduce physician anxiety about prescribing hormones, which is important because they are under-prescribed in general,” Santoro said. “And best of all, removing the black box from topical vaginal estrogen is a big relief, because the tiny incremental increase in circulating estradiol that occurs when women use these preparations should not be compared to the systemic dosing regimens and should not be considered to have the same risk.”
However, “some assumptions and statements made here that go way beyond the data that we have available,” which “raise a bunch of red flags for me.”
“While hormone therapy can indeed be life-changing for symptomatic women, there is not randomized clinical trial evidence that it reduces heart disease, or immune and cognitive decline. There just isn’t,” Santoro said. “And when hormone therapy prescriptions abruptly dropped after the primary WHI publication in 2002, the only population health change that was seen, when hormone therapy went from about 25% of women to less than 2%, was a decrease in breast cancer mortality. There has not been any kind of massive morbidity or mortality as a result of this drop in hormones, although many women suffered with symptoms unnecessarily because of the fear.”
Overall, she said it is “a very good thing that women don’t have to try to decipher the estrogen black box warning (which includes the phrase ‘probable dementia’ and which confuses my patients who read it because they think it means they will probably get dementia if they take estrogen!) and their prescribing clinicians don’t have to have excessive fear of doing harm.”
“[But] the rebirth of the concept that estrogen and hormone therapy are a fountain of youth for women and will extend their lives feels a whole lot like a sharp swing of a pendulum back into the ‘feminine forever’ days.”
