Menopause Hormone Therapy (HRT) in Missoula, MT

Bioidentical hormones in Missoula: what it means

Behind the label "bioidentical hormone replacement therapy" is a plain idea: a hormone whose structure matches the body's own. 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.

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. In the FDA's words, it has no evidence that compounded "bioidentical hormones" are safe and effective. When the National Academies reviewed them in 2020, the evidence was mostly low quality, such as anecdotes and patient reports.

Through VevaMD, a physician licensed in Montana 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.

For its size, Missoula is well supplied with OB-GYNs: the NPI registry lists 22, or 29.1 per 100,000 residents, against 17.8 for the US and above Montana's 14.8. That is about 350 women aged 45 to 64 for each OB-GYN in the city, a ratio rather than a count of open appointments.

Beyond the city line the count barely changes: 22 OB-GYNs within 10 miles and 22 within 25, for the 133,129 people who live in that radius (16.5 per 100,000). Whether or not you have an OB-GYN, you can ask a physician licensed in Montana about menopause hormone therapy online from Missoula, with no waiting room.

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.
