FDA Nixes Certain Boxed Warnings from Hormone Therapy
In what it describes as one of the most sweeping policy shifts in women’s health in decades, FDA says it will begin removing broad boxed warnings from menopause-related hormone replacement therapy (HRT) products. HHS secretary Robert F. Kennedy Jr. and FDA commissioner Marty Makary unveiled the changes at a press conference in Washington where they framed the action as a long-overdue correction to what they called flawed interpretations of early 2000s data that triggered widespread fear about HRT’s safety.
“For more than two decades, bad science and bureaucratic inertia have resulted in women and physicians having an incomplete view of HRT,” an HHS notice says. “We are returning to evidence-based medicine and giving women control over their health again.”
The boxed warnings resulted from the Women’s Health Initiative, a 2002 study involving women with an average age of 63 and using formulations rarely prescribed today, FDA says. Critics have long argued that the study’s age profile and product differences distorted real-world risk for women in their 40s and 50s experiencing menopause.
FDA is now moving to remove boxed language referencing cardiovascular disease, breast cancer, and probable dementia, following a literature review, an expert panel meeting in July, and a public comment period. The agency will retain the boxed warning on endometrial cancer for estrogen-alone products.
Randomized studies cited by HHS show that women who begin systemic HRT within 10 years of menopause onset — or before age 60 — may see reduced all-cause mortality and fracture risk, and significant reductions in cardiovascular and Alzheimer’s disease risk. FDA’s updated labeling will reflect these timing considerations, though individual prescribing decisions remain between clinicians and patients, FDA notes.
Alongside the policy shift, FDA approved two new menopause-related drugs: the first generic version of Premarin in over 30 years, expected to expand access by lowering costs, and a new non-hormonal therapy for moderate to severe vasomotor symptoms such as hot flashes.
