Menopause Hormone Therapy (HRT) in Brentwood, CA

Bioidentical hormones in Brentwood: what it means

If you are one of the 8,919 women aged 45 to 64 in Brentwood and have searched for "bioidentical" hormones: the word means a hormone whose structure matches one the body makes. 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.

Brentwood has fewer OB-GYNs per resident than the country: the federal NPI registry lists 1 with a primary practice address in the city, 1.5 per 100,000 residents against 17.8 nationally and below California's 16.9. That is about 8,920 women aged 45 to 64 for each OB-GYN in the city, a ratio rather than a count of open appointments.

Within 10 miles of the city there are 23 OB-GYNs, and within 25 miles 271, about 16.5 per 100,000 of the 1,639,943 residents in that radius. 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 Brentwood.

Compounded hormones are a different thing: a pharmacy prepares them for one patient, as a cream, a capsule or a pellet. None of these is FDA-approved, and the FDA has not reviewed them for safety, effectiveness or quality before sale. The FDA says it has no evidence that compounded "bioidentical hormones" are safe and effective, or more effective than FDA-approved hormone therapy. When the National Academies reviewed them in 2020, the evidence was mostly low quality, such as anecdotes and patient reports.

You do not choose a "bioidentical" product from a menu: after a private intake, a physician licensed in California decides what, if anything, fits, and the form. Pellets are not part of it. The pharmacy that fills VevaMD prescriptions also compounds, so ask your physician whether yours is an FDA-approved product or compounded. Testosterone cream for women and Bi-Est are compounded and not FDA-approved.

Then there are pellets, implanted under the skin at a clinic; compounded pellets are not FDA-approved. The Endocrine Society cites blood levels well above the expected range in women using compounded pellets. ACOG advises FDA-approved hormone therapy over compounded preparations.
