Menopause Hormone Therapy (HRT) in Westminster, CA

Bioidentical hormones in Westminster: what it means

"Bioidentical" describes a hormone whose chemical structure matches one the body makes. Estradiol and micronized progesterone are both bioidentical: their structure matches the hormones the ovaries make. FDA-approved versions of both are sold by prescription at retail pharmacies.

Only 10 OB-GYNs list a primary practice address in Westminster in the NPI registry. For 90,147 residents that is 11.1 per 100,000, under the US 17.8 and below California's 16.9. With about 12,754 women aged 45 to 64 living in Westminster, that is about 1,280 for each OB-GYN in the city, before counting any younger patients.

Widen the circle and the count grows: 332 in the city or within 10 miles, 1,166 within 25 miles. For the 7,832,068 people who live within 25 miles, that is 14.9 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 Westminster.

"BHRT" often means compounded hormones, a cream, a blend such as Bi-Est or a pellet that a pharmacy mixes for one prescription. They are not FDA-approved, which means the FDA cannot assure their safety or effectiveness. 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.

For women in Westminster, a physician licensed in California can prescribe estradiol (pill, patch, cream or vaginal) and progesterone when they fit your history. There are no pellets. 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.

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