After two decades of caution surrounding hormone therapy,the FDA is poised to remove “black box” warnings from hormone replacement products,a move that coudl reshape treatment options for the millions of women navigating menopause. The agency’s decision, announced November 28, 2023, follows a recent scientific review suggesting the benefits of hormone therapy outweigh the risks for many women when initiated closer to the start of menopause. This shift signals a renewed chance for patients and physicians to discuss personalized treatment plans, and Brazilian medical organizations are already celebrating the potential impact on patient care.

Menopause, a natural transition in a woman’s life, can significantly impact quality of life due to symptoms like hot flashes, mood swings, sleep disturbances, and vaginal dryness. For decades, hormone therapy has been approached with caution following concerns about cardiovascular and breast cancer risks raised by older studies.
Now, a scientific review has prompted the U.S. Food and Drug Administration (FDA) to begin removing prominent warnings from the labels of hormone medications used to treat menopausal symptoms. This change signals a potential shift in how doctors and patients approach managing the challenges of menopause, offering renewed options for relief.

The Brazilian Federation of Gynecology and Obstetrics (FEBRASGO) celebrated the decision, stating it represents an advancement in access to hormone therapy when appropriately indicated. This development creates an opportunity for more women to discuss the safe and informed use of hormones with their healthcare providers.
The FDA announced on November 28, 2023, that it will remove the most serious warnings – known as “black box warnings” – from dozens of hormone products used for menopausal hormone replacement therapy. These warnings, initially introduced over 20 years ago, were based on the 2002 Women’s Health Initiative (WHI) study, which suggested increased risks of cardiovascular disease and breast cancer.
A new FDA evaluation concluded that when hormone therapy is started in women under the age of 60, or within 10 years of the start of menopause, it is both safe and effective for managing symptoms. The review also found benefits including preservation of bone mass and a reduced risk of type 2 diabetes.

This decision doesn’t eliminate all risks, but acknowledges that many women may have been unnecessarily denied a beneficial treatment due to overly broad warnings. The remaining “black box warning” pertains to endometrial cancer risk when estrogen is used without progestin in women who still have a uterus.
What does FEBRASGO say about the news?
FEBRASGO released a statement celebrating the FDA’s decision, noting that it aligns with the organization’s guidance for years: that hormone use can be safe for many women when individualized, with medical supervision and careful evaluation. The organization believes the overly cautious warning previously discouraged many women from seeking treatment that could improve their physical and emotional health during menopause. The FDA’s decision reinforces that hormone therapy, when appropriately indicated, can be another tool for care and well-being.

What are the next steps in Brazil?
While the FDA is a regulatory authority in the United States, its decisions often have repercussions in other countries. In Brazil, the National Health Surveillance Agency (Anvisa) regulates drug labeling and packaging, but pressure from medical societies like FEBRASGO could influence updates based on the best available evidence. This shift in perspective could lead to more informed conversations between doctors and patients about managing menopause symptoms.
For now, Brazilian gynecologists and patients can use this development as a starting point for more balanced discussions. It’s important to remember that hormone therapy isn’t right for every woman, and that a prescription requires individual assessment. However, the FDA’s decision represents a significant change in how the topic will be addressed moving forward.
What does this mean for women?
- Greater autonomy and information when deciding about hormone use.
- The possibility of resuming hormone treatments more comfortably, under medical guidance.
- Updated discussions based on modern evidence, not just older studies.
- Opens the door to learning more about formulations, dosages, duration of use, and real benefits.
