Estradiol Patch Alternatives from a Compounding Pharmacy
If your pharmacy cannot fill your usual estradiol patch, you are not alone, and you have options worth discussing with your prescriber. ProCompounding is a PCAB-accredited 503A compounding pharmacy licensed in all 50 states and the District of Columbia. We prepare compounded topical estrogen preparations to your prescriber's order.
What Is Actually Going On with Estradiol Patches
Demand for estradiol patches rose sharply after the FDA moved to remove boxed warnings from menopausal hormone therapy labels. The FDA announced that decision on November 10, 2025, and approved label changes for the first six products on February 12, 2026.
On September 3, 2026 the FDA said it is aware of reports that patients are having difficulty readily accessing their usual estradiol transdermal patches because of increased demand, that it is working with all six manufacturers to increase supply, and that estradiol transdermal patches remain available. Availability of a particular brand or strength may vary from pharmacy to pharmacy.
The FDA has not placed estradiol transdermal patches on its official drug shortage list, though the American Society of Health-System Pharmacists does list them as being in shortage. We mention this because it is a common point of confusion, and because a compounding pharmacy's options are different from a manufacturer's.
What We Can Prepare
Bi-Est topical (estradiol and estriol)
A combination of estradiol and estriol, compounded in the ratio and strength your prescriber specifies. There is no commercially manufactured Bi-Est product, so this is a preparation only a compounding pharmacy can make.
Estradiol topical
Estradiol prepared on its own, at the strength your prescriber specifies, where they have documented a clinical reason a compounded preparation is needed for you.
Two bases to choose from
Both are available as a hypoallergenic cream or in an olive oil base topical, whichever your prescriber prefers for you.
Micronized progesterone capsules
If your prescriber includes progesterone in your regimen, we prepare micronized progesterone as oral capsules in the strengths they order.
Topical progesterone
We also prepare progesterone as a hypoallergenic cream or in an olive oil base topical, at the strength your prescriber specifies. Whether an oral capsule or a topical is right for you is a decision for your prescriber.
Understanding the Three Estrogens
Human estrogen is not a single hormone. Three forms matter in menopausal hormone therapy, and they differ in potency and in which stage of life each one predominates. Which form or combination is appropriate for you, and in what ratio, is a decision for your prescriber.
Estradiol (E2)
The most potent of the three and the predominant estrogen during the reproductive years. Estradiol is the form contained in commercially manufactured estradiol patches, and it is the form most menopausal hormone therapy is built around.
Estriol (E3)
The weakest of the three and the form that predominates during pregnancy. There is no FDA-approved product manufactured in the United States that contains estriol, which is why an estriol-containing preparation can only come from a compounding pharmacy.
Estrone (E1)
The estrogen that predominates after menopause. Estrone is largely a precursor that the body converts to estradiol, and supplementing it has not been shown to add benefit over estradiol itself. For that reason we do not include estrone in our compounded estrogen preparations — our Bi-Est contains estradiol and estriol only.
Bi-Est is a compounded combination of estradiol and estriol, prepared in the ratio your prescriber specifies. Because there is no manufactured Bi-Est product, the ratio and the strength are written by your prescriber for you specifically.

What We Cannot Do
We do not compound estradiol patches
We do not make hormone patches of any kind. A compounded topical is a different dosage form, not a patch substitute.
We cannot copy a commercial product
A 503A pharmacy cannot compound a preparation that is essentially a copy of a commercially available drug. If your prescriber wants a manufactured estrogen gel, spray or tablet and it is in stock, that prescription belongs at a retail pharmacy.
Compounded preparations are not FDA-approved
They are not reviewed or approved by the FDA for safety or efficacy. FDA approval refers to commercially manufactured products, not to anything we compound.
How to Make the Switch
Do not stop or change your therapy on your own — talk to your prescriber first.
Your prescriber decides whether a compounded topical preparation is appropriate for you, and at what strength.
Your prescriber sends the prescription to us.
We compound it for you and ship it, or hold it for pickup if you are local.
