Menopause Hormone Therapy (HRT) in Irvine, CA

Bioidentical hormones in Irvine: what it means

Behind the label "bioidentical hormone replacement therapy" is a plain idea: a hormone whose structure matches the body's own. Estradiol and micronized progesterone are both bioidentical: their structure matches the hormones the ovaries make. Neither has to be compounded: FDA-approved estradiol comes as pills, patches, gels, sprays, vaginal creams and rings, and progesterone as capsules.

Compounded hormones are a different thing: a pharmacy prepares them for one patient, as a cream, a capsule or a pellet. Compounded drugs are not FDA-approved, so the FDA cannot assure their safety, effectiveness or dose. In the FDA's words, it has no evidence that compounded "bioidentical hormones" are safe and effective. When the National Academies reviewed them in 2020, the evidence was mostly low quality, such as anecdotes and patient reports.

Through VevaMD, a physician licensed in California decides whether hormone therapy fits you and, if so, the form: an estradiol pill, patch, cream or vaginal cream, with progesterone if you have a uterus. Pellets are not part of it. Because the dispensing pharmacy also compounds, you can ask whether your estradiol or progesterone is an FDA-approved product. Two options are compounded for certain: testosterone cream for women and Bi-Est are not FDA-approved.

At 15.6 OB-GYNs per 100,000 residents (48 listed in the NPI registry), Irvine sits near the national 17.8 and below California's 16.9; 40% of the cities VevaMD covers have a lower rate. With about 36,927 women aged 45 to 64 living in Irvine, that is about 770 for each OB-GYN in the city, before counting any younger patients.

Widen the circle and the count grows: 359 in the city or within 10 miles, 676 within 25 miles. For the 4,626,233 people who live within 25 miles, that is 14.6 per 100,000. None of this replaces your own OB-GYN or a menopause doctor you trust; VevaMD adds an online route, with a physician licensed in California reviewing your answers from home in Irvine.

Then there are pellets, implanted under the skin at a clinic; compounded pellets are not FDA-approved. The Endocrine Society points to a study that found hormone levels well above the expected range in women using them. ACOG recommends FDA-approved menopause hormone therapy over compounded hormones.
