Why Your Estradiol Patch Is Hard to Find Right Now
If you couldn't fill your patch, you are not imagining it
Over the past several months, women across the country have gone to refill a prescription they have taken for years and been told their estradiol patch is not in stock. Sometimes it is a particular brand. Sometimes it is a particular strength. Either way it is unsettling, and the calls coming into our pharmacy reflect it.
What changed
On November 10, 2025 the FDA announced it would remove boxed warnings from menopausal hormone therapy labels, and on February 12, 2026 it approved those label changes for the first six products. More women began conversations with their prescribers about hormone therapy, and demand for patches rose sharply. Transdermal patch manufacturing does not scale quickly, because the equipment and processes involved are specialized, so supply has taken time to catch up.
What the FDA actually said
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 also 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. Both of those things are true at the same time, and the distinction is not academic, because it affects what a compounding pharmacy is permitted to do.
What a compounding pharmacy can and cannot do here
We do not make hormone patches of any kind. What a compounding pharmacy can prepare is a different dosage form altogether. Two that we prepare are Bi-Est, a combination of estradiol and estriol, and estradiol on its own, either as a hypoallergenic cream or in an olive oil base topical, at the strength your prescriber specifies. A topical is not a patch and is not a substitute for one. Whether a compounded preparation is appropriate for you, and at what strength, is a decision for your prescriber. One practical difference worth knowing: a compounded topical is applied daily, or as your prescriber directs, whereas a patch is worn for several days at a time.
If you are stuck right now
Do not stop or change your therapy on your own. Ask your pharmacy whether another brand, strength or manufacturer is available. If nothing is, speak to your prescriber about the options, which may include a manufactured alternative or a patient-specific compounded preparation.
