Detailed definition
Compounded HRT is prepared by a 503A compounding pharmacy following a specific prescription for an individual patient. Common formulations include estradiol creams, lozenges, or pellets; "Bi-est" combinations of estradiol and estriol; testosterone creams for women; and combination estradiol-progesterone creams. Compounding offers flexibility — custom doses, removal of common allergens, alternative delivery routes — but the FDA does not approve, test, or certify compounded products for potency consistency or stability. Major menopause societies (NAMS, ACOG, Endocrine Society) generally recommend FDA-approved products as first-line and reserve compounding for situations where no approved product meets the patient's needs (true allergy, dose unavailable commercially, specific combination not available). The 2020 NASEM (National Academies) report on compounded bioidentical hormone therapy was critical of widespread compounding for menopause and recommended tighter regulation.
Why it matters in menopause
Compounded HRT has a legitimate clinical niche but is often oversold as "natural," "safer," or "personalized" relative to FDA-approved alternatives. ClearedRx prescribes both — using FDA-approved products as the default and compounded preparations when there is a specific patient-level reason.
