Menopause Hormone Therapy (HRT) in Petaluma, CA

Bioidentical hormones in Petaluma: what it means

"Bioidentical" describes a hormone whose chemical structure matches one the body makes. Estradiol, the main estrogen the ovaries make before menopause, and micronized progesterone both fit that description. 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. The FDA says it has no evidence that compounded "bioidentical hormones" are safe and effective, or more effective than FDA-approved hormone therapy. The National Academies, reviewing them for the FDA in 2020, called their wide use a public health concern.

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. Since the pharmacy that fills these prescriptions also compounds, ask whether yours is an FDA-approved product or compounded. Two options are compounded for certain: testosterone cream for women and Bi-Est are not FDA-approved.

At 20.2 OB-GYNs per 100,000 residents (12 listed in the NPI registry), Petaluma sits near the national 17.8 and above California's 16.9; 50% of the cities VevaMD covers have a lower rate. With about 8,368 women aged 45 to 64 living in Petaluma, that is about 700 for each OB-GYN in the city, before counting any younger patients.

Widen the circle and the count grows: 18 in the city or within 10 miles, 164 within 25 miles. For the 962,856 people who live within 25 miles, that is 17.0 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 Petaluma.

A pellet clinic is a different model: it implants a hormone pellet under the skin during a visit, and 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.
