Why Is There an Estrogen Patch Shortage, and How Long? (CNBC)
Why is there an estrogen patch shortage, and how long will it last? CNBC's June 2026 reporting puts numbers on it: estrogen patch prescriptions rose 162% over two years to roughly 1.6 million a month by May 2026, up from 594,000 in June 2024, and patches now account for 44% of all estrogen prescriptions. Manufacturer Sandoz described unprecedented demand that cannot be fully met at present on a product it says is highly complex to make, and the FDA's removal of the long-standing boxed warning on hormone therapy turbocharged demand that was already rising. ASHP's Michael Ganio told CNBC the FDA relies on manufacturer-reported supply measured against historical demand, which lags a spike, and he expects a year or two before supply and demand settle. The shortage has spread to several estradiol creams and progesterone pills, and because generic makers plan lines months ahead and may run a patch batch once a year, waiting does not fix it quickly.

Claims this source supports
- Estrogen patch prescriptions increased 162% over two years and reached about 1.6 million a month by May 2026, up from 594,000 in June 2024 (HealthVerity data); patches now account for 44% of all estrogen prescriptions.
- The FDA removed the more-than-20-year-old black box warning on hormone replacement therapy last fall, turbocharging already-rising demand.
- Sandoz said recent prescribing changes created 'unprecedented demand that cannot be fully met at present'; the company is working to increase manufacturing, but patches are 'highly complex' to manufacture.
- ASHP's Michael Ganio: the FDA relies on manufacturer-reported supply against historical demand, which lags a demand spike; he predicts it will take a year or two for supply and demand to find a sweet spot.
- The shortage is spreading to other HRT products - ASHP has listed several estradiol creams and progesterone pills as in shortage.
- Generic manufacturers typically plan production lines months in advance and may run an estradiol patch batch only once a year.
- Dr. Susan Loeb-Zeitlin (Weill Cornell) suggests estrogen gels as an alternative; some prescribers turn to compounding pharmacies, but insurers rarely cover compounded medicines.
