WomenвЂ™s Use and Knowledge of Custom-Compounded Bioidentical Hormones
Nanette Santoro, MD,1 JoAnn V. Pinkerton, MD2
Introduction
FIGURE 1. Survey Recruitment and Eligibility Information
Custom-compounded вЂњbioidenticalвЂќ hormone therapy (CBHT)
is widely advertised as an alternative to conventional FDAapproved prescription hormone therapy for menopausal
symptoms (MHT). FDA approval is not required for CBHT, and
high-quality clinical trials to establish the safety and effectiveness
of these compounded drugs have not been conducted.

TABLE 1. Characteristics of the Survey Cohorts
Demographic
Methods
вЂў Both Harris Interactive and Rose Research fielded an Internet
survey using representative samples drawn from proprietary
nonprobability opt-in panels
вЂў Women were asked about menopausal symptoms, MHT use,
and knowledge of CBHT
вЂў Eligibility:
n HarrisвЂ”women aged 45 to 60 years with current or prior
menopausal symptoms
n RoseвЂ”women aged в‰Ґ40 years with current or prior MHT use
вЂў
Completers were eligible women who answered 100% of
survey questions
вЂў To estimate trends in CBHT use, Rose survey findings were
extrapolated to the US population using Census data1 and
Source Healthcare Analytics PHAST 2.0 prescription data
(Symphony Health, Horsham, PA). For a more detailed
description of the estimations, see poster (P-79) presented at
this meeting.2

Objectives
вЂў Most completers in Rose and Harris were white, had some
post-secondary education/vocational training, and had
healthcare coverage
вЂў Extrapolating data from the Rose survey to the US Census and
PHAST 2.0 data suggests an estimated 1 million to 2.5 million
women aged 40 years and older fill 21 million to 39 million
prescriptions for CHT annually
вЂў Women lacked knowledge of CBHT:
n Three-quarters (76%) of Harris completers did not know
whether вЂњbioidentical hormone therapies compounded
at a specialty pharmacyвЂќ were FDA-approved, and 10%
believed they were FDA-approved
n More than one-quarter (27%) of the 1771 ever-users in Rose
asked about CBHT did not know whether their HT had been
personalized or compounded

There is a dearth of information on the extent of CBHT use in
the United States and on patient awareness of the distinctions
between CBHT and FDA-approved forms of MHT. Two Internet
surveys were conducted to elicit information about US womenвЂ™s
use and knowledge of MHTвЂ”including CBHTвЂ”and their
menopausal experience. Data were extrapolated to estimate the
extent of CBHT use in the United States.

вЂў A large proportion of the US market for MHT consists of CBHT
prescriptions
вЂў An estimated 1 million to 2.5 million US women currently use
CBHT
вЂў Physicians strongly influence womenвЂ™s choice of treatment for
menopausal symptoms
вЂў Most Harris completers (86%) were unaware that CBHT is not
FDA-approved
вЂў More than one-quarter of Rose completers (27%) did not know
whether their HT was personalized or compounded
вЂў This knowledge gap presents an opportunity for providers to
educate patients on the different levels of evidence for the
efficacy, safety, and quality of FDA-approved MHT vs CBHT
