Side Effects Drew Barrymore Publicly Discussed (and What They Match in the Clinical Literature)

What Drew Barrymore Has Said on the Record
In a widely shared 2023 segment of The Drew Barrymore Show, Barrymore told her audience she had entered perimenopause and was "going through it in real time." She described weight fluctuations, difficulty sleeping, and emotional volatility as symptoms she was actively managing. In a follow-up conversation with Dr. Mary Claire Haver on her show, she discussed the option of hormone replacement therapy and said she was weighing the risks and benefits with her physician.
Barrymore has also spoken with People magazine about the roughly 30 pounds of weight change she experienced during her perimenopausal transition, framing it as something she wanted to discuss publicly so other women would feel less alone. "I just want to be honest," she told People in 2023. "This is what my body is doing right now."
What Barrymore has not confirmed publicly: a specific HRT regimen, brand name, dose, or route of administration. Any claims about a particular prescription are speculative. The HealthRX.com Medical Team treats her public statements as the boundary of what can be reported.
At a glance
- Status: Barrymore has publicly confirmed perimenopause and discussed HRT as an option she was exploring with her doctor.
- Specific regimen: Not publicly confirmed. No brand, dose, or formulation has been disclosed.
- Symptoms discussed on camera: Weight gain, sleep disruption, mood changes, hot flashes.
- Clinical match: Every symptom she described appears in the FDA labeling for combined and estrogen-only HRT products as either an indication for treatment or a recognized adverse event.
The Symptoms She Named and Where They Appear in the Literature
Weight Changes
Barrymore spoke candidly about gaining weight during perimenopause. The 2022 Menopause Society position statement notes that the menopausal transition is associated with increased visceral adiposity independent of aging alone. A randomized trial published in Obesity found that oral conjugated equine estrogens slightly attenuated fat mass gain compared to placebo over the study period, though the effect size was modest. The FDA prescribing information for combination estrogen-progestogen products lists "weight changes" as a reported adverse reaction.
So when Barrymore described gaining weight, she was describing a physiologic reality of the perimenopausal window that the clinical literature consistently supports.
Sleep Disruption
Barrymore mentioned trouble sleeping. Night-time awakenings are among the most common complaints in perimenopausal women, and the SWAN study cohort data showed that sleep difficulty increases across the menopausal transition, peaking in late perimenopause. The FDA label for estradiol lists insomnia as a reported event during clinical trials. A Cochrane review found low-certainty evidence that HRT may improve sleep quality in symptomatic menopausal women, though the data remain mixed for women whose primary complaint is insomnia rather than vasomotor symptoms.
Mood Volatility
"I cry at everything," Barrymore said on air. The 2018 JAMA Psychiatry analysis of perimenopausal depression risk confirmed that women in the menopausal transition face a two- to fourfold increased risk of depressive episodes compared to premenopausal controls. Estrogen's role in serotonin receptor modulation is well characterized, and falling estradiol levels during perimenopause are associated with mood destabilization in susceptible individuals. The Endocrine Society's 2015 scientific statement acknowledged hormone therapy as a potential treatment for perimenopausal mood symptoms, though it is not FDA-approved specifically for depression.
Hot Flashes
Barrymore referenced hot flashes in her on-air conversations. Vasomotor symptoms (VMS) are the single most common reason women seek HRT. The WHI estrogen-alone trial and subsequent analyses confirmed that systemic estrogen therapy reduces hot flash frequency by approximately 75% compared to placebo. The FDA specifically approves estrogen and estrogen-progestogen formulations for the treatment of moderate-to-severe VMS associated with menopause.
What the FDA Label Actually Lists as Adverse Events
For women who do initiate HRT (whether or not Barrymore has done so is not publicly confirmed), the FDA prescribing information for systemic estradiol products includes the following adverse reactions reported in clinical trials at rates >5%:
- Headache
- Breast pain or tenderness
- Abdominal pain
- Nausea
- Back pain
- Irregular uterine bleeding
The boxed warning on all systemic estrogen products notes increased risks of endometrial cancer (with unopposed estrogen in women with a uterus), stroke, deep vein thrombosis, and probable dementia in women over 65. These serious risks are dose-dependent and duration-dependent, which is why the FDA recommends the lowest effective dose for the shortest duration consistent with treatment goals.
The WHI combined estrogen-progestogen trial (published in JAMA, 2002) reported a hazard ratio of 1.26 for invasive breast cancer in the hormone group versus placebo over 5.2 years of follow-up. Later reanalysis showed that the absolute risk increase was approximately 8 additional cases per 10,000 woman-years.
The HealthRX.com Medical Team Take
Barrymore's decision to discuss perimenopause on daytime television matters because the condition remains under-discussed relative to its prevalence. Roughly 1.3 million U.S. women enter menopause each year, and a significant fraction experience symptoms that impair daily function.
The HealthRX.com Medical Team observes that every symptom Barrymore named on camera (weight gain, insomnia, emotional volatility, hot flashes) maps directly to the established clinical profile of the perimenopausal transition. She did not exaggerate or medicalize normal variation. She described textbook perimenopause.
What the HealthRX.com Medical Team would add, for any woman watching Barrymore's segments and considering HRT:
-
Timing matters. The "timing hypothesis" suggests that HRT initiated within 10 years of menopause onset or before age 60 carries a more favorable risk-benefit ratio than HRT started later.
-
Route matters. Transdermal estradiol (patches, gels) avoids hepatic first-pass metabolism and carries a lower venous thromboembolism risk than oral formulations, according to observational data from the ESTHER study and the UK GPRD analyses.
-
Progestogen is required for women with a uterus. Unopposed estrogen increases endometrial cancer risk. Micronized progesterone may carry a lower breast cancer risk than synthetic progestins, based on the French E3N cohort data, though head-to-head randomized trials are limited.
-
HRT is not the only option. SSRIs, SNRIs, gabapentin, and cognitive behavioral therapy for insomnia (CBT-I) all have evidence for managing specific menopausal symptoms in women who cannot or choose not to use hormones. The FDA approved fezolinetant (Veozah) in 2023 as the first non-hormonal neurokinin-3 receptor antagonist for VMS.
Barrymore's openness gave her audience permission to name what they were feeling. The clinical literature gives those named symptoms a measurable, treatable framework.
