Menopause Hormone Therapy (HRT) in Vacaville, CA

Bioidentical hormones in Vacaville: what it means

Behind the label "bioidentical hormone replacement therapy" is a plain idea: a hormone whose structure matches the body's own. Estradiol, the main estrogen the ovaries make before menopause, and micronized progesterone both fit that description. Both come in FDA-approved prescription forms, from estradiol pills, patches, gels and vaginal forms to progesterone capsules.

Many products sold as "bioidentical hormones" or "BHRT" are compounded instead: mixed by a pharmacy for one prescription, often as a custom cream 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 also says it has no evidence that they are safe and effective, or more effective than approved hormone therapy. A 2020 National Academies review found no rigorous evidence of their safety and effectiveness.

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 17.6 OB-GYNs per 100,000 residents (18 listed in the NPI registry), Vacaville sits near the national 17.8 and about level with California's 16.9; 45% of the cities VevaMD covers have a lower rate. With about 12,029 women aged 45 to 64 living in Vacaville, that is about 670 for each OB-GYN in the city, before counting any younger patients.

Widen the circle and the count grows: 40 in the city or within 10 miles, 117 within 25 miles. For the 801,114 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 Vacaville.

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's guidance is to prefer FDA-approved menopause hormone therapy to compounded hormones.
