Menopause Hormone Therapy (HRT) in Thousand Oaks, CA

Bioidentical hormones in Thousand Oaks: 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.

Only 19 OB-GYNs list a primary practice address in Thousand Oaks in the NPI registry. For 125,676 residents that is 15.1 per 100,000, under the US 17.8 and below California's 16.9. That is about 980 women aged 45 to 64 for each OB-GYN in the city, a ratio rather than a count of open appointments.

Widen the circle and the count grows: 49 in the city or within 10 miles, 305 within 25 miles. For the 1,892,899 people who live within 25 miles, that is 16.1 per 100,000. Whether or not you have an OB-GYN, you can ask a physician licensed in California about menopause hormone therapy online from Thousand Oaks, with no waiting room.

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.

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. VevaMD does not offer pellets. 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.

BHRT pellet clinics work differently: they place a hormone pellet under the skin in the office, 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 advises FDA-approved hormone therapy over compounded preparations.
