Key Takeaways
-
Compounded hormone formulations are patient-specific preparations of estradiol, progesterone, testosterone, or DHEA, prepared to the strength and delivery form the prescriber orders.
-
Four dosage forms cover most compounded hormone prescriptions in a 503A pharmacy: transdermal creams and gels, sublingual or buccal troches, oral capsules, and vaginal preparations. Each behaves differently in practice.
-
Five elements belong on every compounded hormone prescription: each active and its strength, strength per unit or percent concentration, the base or vehicle, quantity or days supply, and directions including application site.
-
NASEM and ACOG both recommend restricting compounded hormone therapy to patients who cannot use an FDA-approved product. Salivary hormone testing is not a validated basis for dosing.
Compounded hormone formulations are patient-specific preparations of estradiol, progesterone, testosterone, or DHEA, prepared to the strength and delivery form you order. They solve what manufactured products cannot: a reactive excipient, a strength that isn't made, a route the patient needs.
The pharmacology isn't the hard part for most prescribers. The operational detail is: which dosage forms are available, what belongs on the prescription, and where the societies stand.
Which Compounded Hormone Dosage Forms Are Available?
Four dosage forms cover the large majority of compounded hormone prescriptions in a 503A community pharmacy. The clinical question is rarely which one is best in the abstract. It is which one this patient will use correctly for the next twelve months.
| Dosage form | Route | Practical considerations |
|---|---|---|
| Transdermal cream or gel | Absorbed through thin skin, typically inner forearm, inner thigh, or upper chest | Delivered dose depends on consistent application site, surface area, and skin condition. Secondary transfer to a partner or child is a real counseling point. Metered pumps or unit-dose syringes reduce variability compared with a jar. |
| Sublingual or buccal troche | Dissolved against the mucosa | Fast onset. Accuracy depends on the patient letting it dissolve fully rather than chewing or swallowing it, which shifts exposure toward first-pass metabolism. A flavored base improves adherence. |
| Oral capsule | Swallowed, subject to first-pass hepatic metabolism | The most familiar form for patients, and frequently the reason a script comes to a compounder at all. Commercially available micronized progesterone capsules are formulated in peanut oil, so a documented peanut allergy requires an alternative base. |
| Vaginal cream, insert, or suppository | Local delivery to vaginal and vulvar tissue | Used where the target is genitourinary symptoms rather than systemic replacement. Base selection materially affects patient tolerance. |
DHEA and pregnenolone requests come up regularly in this category. Both are widely available as unregulated dietary supplements, which is exactly why prescribers ask a compounder for a known, verified strength instead. Both also sit outside the evidence base that supports estradiol and progesterone therapy, and ACOG has been explicit that compounded preparations of these should not be presented to patients as equivalent to studied, approved therapy.
What Should a Compounded Hormone Prescription Specify?
Five elements. A prescription missing any of them will generate a callback, which costs your staff a phone call and costs the patient a day.
-
Active ingredient or ingredients, named specifically. For combination preparations, name each active and its individual strength rather than a proprietary formula name.
-
Strength per unit, or percent concentration for topicals. A cream ordered as "0.1%" and a cream ordered as "1 mg per 0.1 mL" are not the same instruction. Percent concentration plus total volume is unambiguous for creams and gels. Milligrams per unit is unambiguous for troches and capsules.
-
The base or vehicle. This is the field most often left blank, and the one that most often triggers a callback. If a patient has a documented excipient allergy, name what to avoid. If you have no preference, say so, and the pharmacist will select an appropriate base and tell you which one was used.
-
Quantity or days supply. Beyond-use dates on compounded preparations are shorter than commercial expiration dates, so a ninety-day supply is not appropriate for every formulation. The pharmacist can tell you what the stability data supports.
-
Directions, including application site for topicals. Site rotation instructions and transfer precautions belong in the sig, not only in the counseling.
If a formulation is new to you, calling the compounding pharmacist before writing takes less time than the correction cycle afterward. That consultation is a standard part of how we work with prescribing practices.
What Do NASEM and ACOG Say About Compounded Hormone Therapy?
Both recommend restricting compounded hormone therapy to patients who cannot use an FDA-approved product. This is the consensus position, and stating it plainly is more useful to a prescribing practice than working around it.
The National Academies of Sciences, Engineering, and Medicine published a review of compounded bioidentical hormone therapy in 2020, concluding that the evidence does not support routine use and recommending that use be limited to circumstances where an approved product is not clinically appropriate. ACOG has taken a consistent position, favoring FDA-approved products for most patients and noting that compounded preparations lack the safety and efficacy review approved products undergo.
The carve-outs both bodies recognize are the same ones that make up most legitimate compounding volume:
-
A documented allergy or sensitivity to an ingredient present in every commercially available version
-
A strength that is not commercially manufactured
-
A dosage form the patient requires that is not commercially available
Two related points are worth having ready for patient conversations. First, "bioidentical" describes molecular structure, not regulatory status, and several FDA-approved products contain bioidentical estradiol and progesterone. Second, salivary hormone testing is not a validated basis for dosing compounded hormone therapy, and both NASEM and ACOG have said so. Patients frequently arrive having already paid for one.
How JAD Family Pharmacy Prepares Compounded Hormone Prescriptions
JAD Family Pharmacy is an independent 503A pharmacy in Titusville, Florida, licensed by the Florida Board of Pharmacy and compounding under USP Chapter 795 standards for non-sterile preparations. Prescribers reach a compounding pharmacist directly to discuss a base, a concentration, or a stability question before writing.
Preparations are made against a patient-specific prescription, labeled with lot number and beyond-use date, and dispensed with counseling on administration and transfer precautions. Details on the service line are on our hormone replacement therapy compounding at JAD Family Pharmacy page, alongside men's health compounding and our full compounding service list.
Patients receive free prescription delivery throughout Brevard County on compounded preparations, and refills can be synchronized with the rest of their medications so a hormone regimen does not lapse on a scheduling gap.
Frequently Asked Questions
Are compounded hormone preparations FDA-approved?
No. No compounded preparation is FDA-approved, and none undergoes premarket review for safety, efficacy, or quality. The active ingredients may be approved substances sourced with a certificate of analysis, but the finished preparation is not an approved drug product. Patients should hear this directly from the prescriber.
When is compounding justified instead of an FDA-approved hormone product?
When an approved product cannot meet the clinical requirement. The recognized situations are a documented excipient allergy, a strength that is not commercially manufactured, or a dosage form the patient needs that is not commercially made. Documenting which one applies supports the clinical rationale in the chart.
Should I use salivary hormone levels to adjust a compounded dose?
Salivary testing is not a validated method for titrating hormone therapy. Both the 2020 National Academies review and ACOG have addressed this directly. Serum testing, interpreted alongside symptoms and the specific dosage form and route in use, remains the appropriate basis for monitoring.
How does a transdermal cream compare to a troche for absorption?
They differ in route rather than in potency. A cream bypasses first-pass metabolism and delivers a dose that varies with application site, surface area, and skin condition. A troche absorbs across the oral mucosa quickly, but any portion swallowed shifts toward hepatic first-pass metabolism, which changes exposure.
What beyond-use date do compounded hormone preparations carry?
It depends on the formulation, the base, and the storage conditions, and it is assigned under USP Chapter 795 rather than chosen by preference. Beyond-use dates are shorter than commercial expiration dates, so ask the pharmacy what the stability basis supports before ordering an extended supply.
Can a compounded hormone prescription be sent electronically?
Yes. Send it the way you send any prescription. Include each active and its strength, the dosage form and base, quantity or days supply, and directions with application site for topicals. For an unfamiliar formulation, a short call to the compounding pharmacist before transmitting usually prevents a callback.
