Dr. Heidi Queen, MD | Energize Health & Hormones
If you’ve recently had trouble filling a prescription for hormone therapy, you’re not alone — and you’re not imagining things. Across the United States and around the world, shortages of estrogen products and other medications have become increasingly common.
Much of what we currently understand about these shortages has been carefully explained by gynecologist and menopause expert Dr. Jen Gunter, who recently updated her widely read Hormone Therapy Guide. Her work helps clarify an important reality: hormone shortages are not caused by one simple problem. Instead, they reflect a fragile global medication system that affects far more than menopause care. For patients working with Dr. Heidi Queen, understanding the why behind shortages can make the situation far less frustrating — and help patients make confident, informed decisions when adjustments are needed.
The Bigger Picture: Drug Shortages Are Everywhere
Hormone therapy is only one piece of a much larger issue. Over the past several years, drug shortages have risen sharply worldwide. Hundreds of medications — including antibiotics, anesthetics, chemotherapy drugs, and hormones — have experienced supply disruptions.
Unlike temporary retail shortages, medication shortages often last a long time. In the United States, the average shortage persists for well over a year, and hormone-related medications may remain limited even longer. Several factors contribute:
- Global supply chains stretched across multiple countries
- Highly specialized manufacturing processes
- Limited numbers of factories producing certain medications
- Regulatory requirements that slow rapid replacement of suppliers
- Economic pressures favoring lower-cost production over supply stability
In short, modern medicine depends on a system that works efficiently — but not always resiliently.
Why Hormones Are Especially Vulnerable
Hormone therapy medications such as estradiol and progesterone have unique production challenges that make them particularly sensitive to disruption. Surprisingly, many hormone medications begin with soybeans. A plant compound derived from soy is used as the starting material for synthesizing estrogen and progesterone. When crop yields decline due to climate events or agricultural disruptions, the effects ripple through the entire pharmaceutical pipeline months later.
From there, production becomes even more concentrated. Much of the world’s raw hormone ingredients — known as active pharmaceutical ingredients (APIs) — are manufactured primarily in China and India. When only a few regions supply critical materials, even a single factory shutdown, contamination issue, or geopolitical disruption can affect global availability.
Adding to the complexity:
- Manufacturing hormones requires specialized facilities that cannot quickly switch production.
- Drug approvals are tied to specific ingredient suppliers, meaning companies cannot easily change sources during shortages.
- Generic medications are often produced only after orders are placed, leaving little reserve inventory when demand suddenly rises.
The result is a system where even strong demand and available funding cannot instantly restore supply.
Why Brand Names Sometimes Stay Available
Patients often notice that generic medications disappear first while brand-name versions remain available. This isn’t accidental. Brand manufacturers typically secure long-term supply contracts and backup production agreements — protections built into higher pricing structures. Larger generic companies may also produce their own raw ingredients, but smaller manufacturers often rely on outside suppliers and are more vulnerable when shortages occur.
Insurance coverage can complicate switching, but sometimes a temporary move from generic to brand medication is the most practical solution.
What Patients Can Do During a Hormone Shortage
While patients cannot control global supply chains, there are practical steps that can help maintain continuity of care. Dr. Queen frequently reminds patients that flexibility — guided by medical supervision — is key during shortages.
- Try a Different Pharmacy
Inventory varies widely between pharmacies. Mail-order options, warehouse pharmacies, or transparent pricing services may carry doses unavailable locally. A prescription can often be transferred easily.
- Consider an Equivalent Formulation
Estrogen therapy comes in multiple forms:
- Patches
- Gels or sprays
- Vaginal rings
- Oral tablets
Although these deliver hormones differently, many provide comparable symptom relief when doses are appropriately adjusted. Switching formulations can often bridge a temporary shortage.
Because absorption differs between oral and transdermal estrogen, any change should be guided by a clinician familiar with your health history.
- Adjust the Dose (When Appropriate)
If a specific patch strength is unavailable, clinicians may recommend:
- Using two lower-dose patches
- Switching to a nearby equivalent dose
- Gradually lowering dosage if symptoms allow
Many patients several years past menopause tolerate modest dose reductions without difficulty — and lower doses still provide meaningful bone protection and symptom control.
- Cutting Estradiol Patches — When It’s Safe
One strategy receiving attention during shortages is cutting patches to achieve an available dose. This can work only with certain patch types.
Estradiol patches come in two designs:
- Matrix patches: medication is evenly distributed in the adhesive and may be cut.
- Reservoir patches: contain liquid hormone behind a membrane and must never be cut, as medication can leak out.
A simple rule often used clinically:
Matrix can be made smaller; reservoir patches resist cutting.
Patients should always confirm patch type and discuss this approach with their healthcare provider before trying it.
- Oral Estrogen as a Temporary Option
Although transdermal estrogen is often preferred due to lower clot risk, oral estrogen remains appropriate for many healthy patients at low cardiovascular risk. For some individuals, switching temporarily to oral therapy may be safer than stopping treatment altogether.
- Perimenopause May Have Different Options
For people still in perimenopause, low-dose hormonal contraceptives can sometimes manage symptoms more effectively than traditional menopause hormone therapy, particularly when irregular bleeding or mood swings are dominant concerns.
A Reminder: Your Pharmacist Isn’t the Problem
One of the most important takeaways from experts studying shortages is this: pharmacists have no control over medication supply. They are often just as frustrated as patients and providers when medications cannot be obtained. The causes lie upstream — in manufacturing systems, regulatory processes, and global supply networks.
The Role of Personalized Care
Medication shortages highlight something Dr. Queen emphasizes in her concierge primary care model: healthcare works best when it is collaborative and adaptable. Hormone therapy is never one-size-fits-all. Dose adjustments, formulation changes, or temporary alternatives can often maintain symptom relief safely when guided by a clinician who understands your full medical picture.
Rather than stopping therapy abruptly or relying on online advice alone, patients benefit most from individualized planning that balances symptom control, safety, and available options.
Looking Ahead
Hormone shortages are unlikely to disappear quickly. Experts warn that modern pharmaceutical supply chains remain fragile, and meaningful policy changes may take years. But understanding the reasons behind shortages can reduce anxiety — and knowing the available workarounds empowers patients to stay on track with treatment. If you encounter difficulty obtaining hormone therapy, the best next step is not panic, but conversation. With thoughtful adjustments and professional guidance, most patients can continue care safely even when supplies fluctuate.
