Estrogen patch shortage: what are your alternatives, and is hormone pellet therapy right for you?

By Gustav Lo, MD | Chief Medical Officer

Many women begin hormone replacement therapy using estrogen patches, one of the most commonly prescribed treatments for menopause symptoms such as hot flashes, night sweats, and sleep disturbances.

Recently, many pharmacies across the United States have been affected by an estradiol patch shortage, leaving patients searching for alternatives. For many women, this shortage has become the catalyst for a broader conversation about which hormone delivery method is actually best for them.

In this article, I will explain how estrogen patches and hormone pellets compare, why the shortage has prompted so many patients to reconsider their options, and how individualized, physician-guided therapy — the foundation of the RegenHRT methodology — can make a meaningful difference in long-term outcomes.

Is there an estradiol patch shortage right now?

Yes. Pharmacies across the United States have reported widespread shortages of estradiol patches, including several of the most commonly prescribed brands and dosages. Patients have reported being unable to refill their prescriptions on schedule, and many have been turned away from multiple pharmacies.

Supply chain disruptions affecting transdermal patch manufacturing have contributed to the shortage, and availability has been inconsistent across regions. For patients who rely on estrogen patches to manage menopause symptoms, this has created uncertainty and urgency.

The good news is that effective hormone therapy does not depend on patches alone. Understanding your options — and the clinical differences between them — can help you make a confident, informed decision.

How estrogen patches work, and why patients are looking for alternatives

Estrogen patches deliver hormones through the skin using a what is known as a transdermal delivery system. The patch is applied to the body and replaced every few days, allowing estrogen to absorb gradually into the bloodstream.

This method became popular because it avoids the risks associated with oral estrogen. When estrogen is taken as a pill, it must pass through the liver before entering the bloodstream. The liver responds by producing additional clotting factors, which increases the risk of blood clots. Transdermal delivery bypasses this “first-pass” liver effect and significantly reduces that risk.

Beyond the current shortage, however, patches have limitations that are worth understanding — limitations that affect whether patients are actually receiving the full benefit of hormone therapy.

The hidden issue with traditional estrogen patch therapy

One of the biggest challenges with traditional hormone therapy is how it has historically been prescribed.

When I began practicing medicine, hormone therapy was extremely simple. We didn’t routinely measure hormone levels. There were essentially two options: a smaller dose or a larger dose. If a patient’s hot flashes improved, the treatment was considered successful.

Even today, typical hormone therapy regimens still follow the same pattern. But symptom relief doesn’t mean hormone levels have been restored to optimal ranges. You can usually get rid of your hot flashes with even the lowest-dose estrogen patch, but that usually doesn’t raise estrogen to levels that protect bones, blood vessels, or brain function. This brings up the central point that’s being missed in menopausal treatment in the US: hormone replacement therapy shouldn’t be focused only on symptoms – it’s even more important to protect women from future diseases and risks like osteoporosis, heart attacks and strokes, and Alzheimer’s disease, to name just a few.

It is estimated that 75% of women using estradiol patches in the US are not reaching optimal levels. Not only may they not be feeling or functioning as well as they could, but they’re also not providing the best protection for their bones, brains, or blood vessels. And remember, these are women who are trying to be proactive and do the best thing for their health!

How hormone pellet therapy works

Hormone pellets use a different delivery method. Pellets are tiny implants about the size of a grain of rice, placed just under the skin during a quick office procedure. Once inserted, they slowly releases hormones into the bloodstream over several months. It’s like a time-release capsule, except under the skin.

Because pellets release hormones continuously, they can produce more stable hormone levels compared with patches, which must be replaced every few days. Patches tend to release much more of their active ingredient in the first 24 hours, and much less over the remaining days. In our practice, we typically find that women have very low hormone levels about 4-5 days a week. Fluctuating levels from patch changes can contribute to inconsistent symptom control.

Another important difference is dosing. Pellet therapy allows physicians to tailor hormone levels more precisely to each patient. Instead of relying on a few standardized patch doses, treatment can be adjusted based on laboratory testing and clinical response — which is central to the RegenHRT physician-guided hormone therapy model.

Topical cream and gel – if you don’t like the idea of pellets

Some patients don’t like the idea of pellets – for a variety of reasons. For those situations, we pivot to topical compounded estradiol cream and testosterone gel. At RegenCen, we dispense these in FDA-approved metered dose devices, which again allows our providers to adjust dosing to achieve optimal levels (which can be difficult with patches). Topicals can be fussy too though, with levels that may fluctuate more than with pellets.

Ultimately, it’s good to have choices. The key is to bring your hormone levels into a range that not only restores how you feel every day, but also supports long-term health—using a delivery method that fits comfortably into your life and routine.

The RegenHRT approach: personalized, physician-guided hormone therapy

RegenHRT is RegenCen’s proprietary model for hormone therapy — built on the principle that effective treatment requires individualization, not standardization. This is distinct from the traditional symptom-only approach, where a single patch dose is prescribed and only adjusted if complaints arise.

The RegenHRT approach emphasizes:

• Baseline lab testing before treatment, so we know each patient’s starting hormone levels
• Individualized dosing based on physiology, symptoms, and laboratory results, not one-size-fits-all formulas
• Ongoing monitoring with follow-up evaluations to ensure hormone levels remain balanced over time
• Provider oversight at every stage, so treatment can evolve alongside each patient’s needs
• Providers certified by The Menopause Society, so you can be confident your provider is both highly knowledgeable and current with the latest advances in menopause care.

Why hormone level monitoring matters: it’s not just symptom relief

When most people think about menopause, they think about hot flashes. But hot flashes are only one manifestation of a much larger biological change.

Estrogen receptors exist throughout the body, including in the brain, bones, skin, blood vessels, genitourinary system, and internal organs. When estrogen binds to these receptors, it triggers cellular signals that get the machinery of those cells moving and doing their jobs. When estrogen disappears, those signals vanish. As FDA commissioner Dr. Marty Makary said on November 10, 2025, “When estrogen vanishes, a cascade of disease and aging begins.” Blood vessels begin to deteriorate. Bone loss accelerates. Muscle mass declines. Skin becomes thinner and drier. Vaginal and urinary complaints abound.

This is why hormone therapy is increasingly viewed not just as symptom relief, but as a way to maintain the biological systems crucial for long-term health. And it is why the dose, delivery method, and ongoing monitoring of hormone therapy matter so much.

When hormone pellets may be a better option than estrogen patches

Estrogen patches are commonly prescribed for hormone therapy, but in routine clinical use they are dosed conservatively and usually do not achieve estradiol levels associated with optimal biological effects. While women often have symptom relief with patches, laboratory testing frequently shows levels that remain below physiologic ranges linked to bone density, vascular health, and overall tissue function. We have found this to be almost universally true when we test our patients who are already on patches from other providers.

In addition, skin absorption from patches varies dramatically between individuals, and even with appropriate use, blood levels of estradiol fluctuate over the dosing interval.

For these reasons, women can benefit from alternative delivery methods such as hormone pellet therapy or topical creams or gels, particularly if they:

• Continue to experience symptoms despite patch therapy
• Have low estradiol levels on laboratory testing
• Require higher or more stable hormone levels to achieve clinical goals
• Prefer a delivery system that avoids day-to-day variability and frequent dosing
• Are affected by ongoing estradiol patch availability issues

Pellet therapy allows for more consistent hormone delivery over time and may be better suited for women seeking to achieve and maintain physiologic hormone levels rather than symptom control alone. Pellets also offer a practical advantage: once inserted, they release hormones continuously for several months, creating more stable hormone levels and eliminating the need to remember frequent patch changes.

Topical creams or gels offer offer on-demand adjustments of hormones for those concerned about long acting pellets, with the trade-off of perhaps some increased variability of levels.

Estrogen patches vs. hormone pellets vs. topicals: which is better?

There is no single hormone therapy delivery method that works best for every patient. Both estrogen patches and hormone pellets can be effective treatments depending on the individual. The most important factor is not simply the delivery method, but how therapy is managed.

Effective hormone therapy requires individualized dosing, physician oversight, regular hormone monitoring, and treatment tailored to each patient’s physiology. When these principles are followed, hormone therapy can play an important role in maintaining health during menopause and beyond.

Conclusion

Estrogen patches remain one of the most widely prescribed treatments for menopause,but the current estradiol patch shortage has many women exploring their alternatives for the first time — and that exploration is worth taking seriously.

Hormone pellets and compounded topicals offer an alternative delivery method that provides steady, continuous hormone release and allows for more individualized dosing. When managed carefully under physician guidance, hormone therapy can do more than relieve symptoms — it maintains the biological systems for long-term health.

Frequently asked questions about estrogen patches and hormone pellet therapy

Is there an estrogen patch shortage right now?
Yes. Pharmacies across the United States are currently experiencing widespread shortages of estradiol patches. Availability varies by region and brand. Patients who cannot fill their prescription are encouraged to speak with their physician about alternative hormone therapy options, including hormone pellet therapy.

What can I use instead of an estrogen patch?
If estrogen patches are unavailable, alternative hormone therapy options include estrogen creams, gels, sprays, and hormone pellet therapy. Pellet therapy provides a long-acting option that releases estrogen steadily over several months, without reliance on patch availability.

What is RegenHRT?
RegenHRT is RegenCen’s physician-guided hormone therapy model, built around individualized dosing, baseline and ongoing lab testing, and physician oversight at every stage. Rather than prescribing a standard dose and adjusting only if symptoms persist, the RegenHRT approach aims to restore hormone levels to optimal physiological ranges for each patient.

Are hormone pellets safer than estrogen patches?
Both patches and pellets can be safe when prescribed appropriately by a physician. The most important factor is individualized dosing and medical supervision, not simply the delivery method.

Do hormone pellets last longer than estrogen patches?
Yes. Estrogen patches typically need to be replaced every few days. Hormone pellets are inserted under the skin and release hormones gradually for several months, providing more consistent hormone levels and eliminating the need for frequent replacements.

Why might hormone therapy not relieve all symptoms?
In some cases, symptoms persist because hormone levels remain below optimal ranges. A standard patch dose that eliminates hot flashes may not raise estrogen high enough to protect bone density, cardiovascular health, or cognitive function. Monitoring hormone levels through lab testing allows physicians to adjust dosing and improve results.

How do I know if hormone pellet therapy is right for me?
The best way to determine whether pellet therapy is appropriate is to consult with a physician who specializes in hormone therapy. At RegenCen, the RegenHRT evaluation begins with baseline lab testing and a thorough review of symptoms, health history, and treatment goals.
