The Estrogen Patch Shortage: What to Ask For When Your Patch Isn't Available

I have had some version of this conversation more times this year than I can count. A message lands in my Instagram DMs, a patient calls, someone writes through the portal, or catches me at The 'Pause Wellness, and it is always some version of the same thing: my pharmacy does not have my patch, nobody can tell me when it will, and I do not know what to do.

The situation is more complicated than a simple shortage. Here is what is happening and what to do about it.

First, this is not a prescription, it is a conversation tool. Do not change your dose, your route, or your progestogen on your own. Every option here requires a new prescription and a clinician who knows your history.

What is Happening? Is There an Estradiol Patch Shortage?

The American Society of Health-System Pharmacists lists estradiol transdermal system on its active drug shortage list. The FDA disagrees, saying patches are not officially in shortage and that all six manufacturers are producing at full capacity to meet rising demand. Both are true, and the gap matters: without an official shortage designation, the problem gets less regulatory urgency and your pharmacy has fewer tools to substitute freely, even while the shelf is empty.

Why it is slow to resolve: patches are harder to make than tablets, and generic manufacturers often run one product for part of the year before switching the line to something else. This is a manufacturing constraint working itself out, not a company withholding a fix.

If your patch is unavailable, report it to the FDA at drugshortages@fda.gov or through the FDA drug shortage reporting page. The agency relies in part on these reports to decide when to designate a shortage. Your report is what closes the gap between what you are living and what the FDA officially recognizes.

Before You Change Anything, Ask This First

The shortage is manufacturer-specific, not category-wide. Some companies are short right now, others are shipping normally. So the best first fix is often a different patch, not a different kind of medication. If the transdermal route matters for your health history, and for some women it genuinely does, protect it before moving to something else.

This shifts weekly, so treat it as a starting point with your pharmacist, not a guarantee of what is on the shelf. From the most recent ASHP update:

Reported available: Sandoz once-weekly patches, Viatris (Mylan) once-weekly and twice-weekly patches, and Bayer's Climara once-weekly patches.

Reported on shortage: Amneal's Dotti and Lyllana twice-weekly patches (no reason given), Noven, distributed by Grove Pharmaceuticals (increased demand), and Zydus (no reason given).

5 Questions for Your Pharmacist About the Estrogen Patch Shortage

I hand patients a version of this list. It moves faster than a general question about whether a prescription is in stock. Try to order your refill about two weeks before you apply your last patch. That gives you some breathing room if your pharmacy has a delay.

1. Can this be filled with a different manufacturer's estradiol patch?
2. If my twice-weekly patch is unavailable, is a once-weekly available, or the reverse?
3. Is there a different strength in stock that my clinician could work with?
4. Can you check other locations in your chain, or a 90-day or mail-order fill?
5. If nothing is available, can you call my clinician directly with what you do have?

Do not skip that last one. A phone call between a pharmacist and a prescriber can solve in five minutes what might otherwise take three more visits to sort out.

And, of course, you can always ask for a transfer to another pharmacy if you find your preferred patch elsewhere. Many pharmacies can do this, but they may not suggest it unless you ask.

What Are the Alternatives to an Estradiol Patch?

If a different patch is not available, you have more options than most women are offered at the counter. They are listed here in order of how closely each one preserves what your patch was doing for you.

Another patch, on a different schedule or strength. Still the first move if available. Switching between once-weekly and twice-weekly, or a different strength your clinician can work with, keeps you on the exact delivery method you already use.

Gel or spray. These keep you on the transdermal route and are the closest match to a patch, which matters if staying off oral estrogen is important for your health. Options include EstroGel and Elestrin gels, Divigel packets, and Evamist spray. Your clinician titrates these to your response rather than reading a dose off a chart.

A systemic vaginal ring. Femring delivers estrogen to the whole body, unlike other vaginal rings that work only locally. A legitimate systemic option worth asking about.

An oral tablet. For most women, moving from a patch to a tablet is reasonable when patches are not available. But oral estrogen is not the right default for everyone, for reasons in the safety section below.

A combination product. If you are switching anyway, products that include both estrogen and progestogen can simplify a complicated medication list: Bijuva, Activella, Amabelz, Angeliq, Prefest, and Combipatch. Duavee, which pairs conjugated estrogens with bazedoxifene, protects the endometrium without a separate progestogen at all.

A different pharmacy entirely. If nothing is available locally, an online or mail-order pharmacy may have supply the local store does not, including GoodRx, Cost Plus Drugs, and The HRT Club. A 90-day mail-order fill also buys a longer runway between refills.

A Guide to Dose Equivalency

If a switch turns out to be necessary, you and your clinician need a shared reference point for what counts as an equivalent dose. I lean on the Canadian Menopause Society's Systemic Menopause Hormone Therapy Equivalency Table for this, because it is built on genuine expert consensus drawing from British and International Menopause Society guidance rather than being invented from thin air.

These are approximations, not precise conversions. No robust head-to-head studies exist across every formulation, and absorption varies both between products and between individual women. Your body will not necessarily behave exactly like a chart. The table spans ultra low, low, standard, moderate to high, and high dose ranges, with the high range generally reserved for women with premature ovarian insufficiency or surgical menopause, who typically need more estrogen than a woman going through natural menopause.

A few products live outside this consensus table entirely, and they are legitimate options even without a published equivalency. Elestrin gel, Evamist spray, Femring, and Menostar, which is an ultra-low dose patch approved specifically for osteoporosis prevention rather than for hot flashes. For any of these, your clinician will titrate to your symptoms rather than convert from a chart, which is exactly right.

This next point gets glossed over too often, and the Canadian Menopause Society flags it specifically. Ultra-low dose formulations, like Divigel at 0.25 mg, are not simply smaller versions of a standard dose. Be cautious if you are switching into one. If ultra low is all your pharmacy has on the shelf, that is a different treatment being offered, not a scaled-down version of the one you were already on.

US products with no published equivalency

These are legitimate options. They simply are not in the consensus table, so your clinician will be titrating to your symptoms rather than converting from a chart.

Ultra low is not a smaller version of standard

The Canadian Menopause Society flags this specifically: ultra-low dose formulations such as Divigel 0.25 mg are not equivalent to standard doses and should be used cautiously when switching. If ultra low is all your pharmacy has, that is a different treatment, not a smaller one.

What Actually Changes When the Route Changes?

This is the part to get right, because it is about safety, not convenience. Oral and transdermal estrogen are not interchangeable for every woman, and the reason comes down to basic physiology. Estrogen taken by mouth passes through the liver before it reaches the rest of the body. Estrogen absorbed through the skin does not. That single difference is why transdermal delivery is generally preferred for women with a history of blood clots, elevated triglycerides, migraine with aura, or a higher BMI.

For most women, moving from a patch to a tablet is a reasonable option if patches are not available. But for women in those higher-risk categories, this is a clinical decision that deserves a real conversation, not a default substitution made only because the patch happened to be out of stock that week. Gel and spray keep you on the transdermal route and are the closest structural match to a patch if staying off oral estrogen matters for your health.

Key Takeaway: Your Progestogen Does Not Change

This is the single highest-consequence line in this entire guide. If you have a uterus, your endometrial protection needs to continue uninterrupted through any estrogen switch. Progestogen should not be paused while you sort out the estrogen piece. That is not a place to improvise.

Progestogen dosing is calibrated to match the estrogen dose level alongside it, which means higher estrogen doses often call for proportionally higher progestogen. Unscheduled bleeding can also call for an increased progestogen dose even at a lower estrogen level. This is a conversation to have out loud with your clinician, not a guess to make alone.

Progestogen doses shown correspond to the estradiol dose level in the same column. Higher estrogen doses often require proportionally higher progestogen. Unscheduled bleeding may call for 200 mg daily continuous or 300 mg sequential, even at lower estrogen doses. Norethindrone acetate (Aygestin) 5 mg is an additional option.

Do not confuse two things here. Vaginal estrogen, including Estring and various creams, tablets, and inserts, treats genitourinary symptoms locally. It was never designed to replace a systemic patch, and it will not. Femring is the one true exception, since it delivers estrogen systemically despite being a vaginal ring. The reverse is worth knowing too: genitourinary symptoms can persist even at standard systemic doses, and local therapy can be layered on top without changing your systemic progestogen requirement at all.

Seven Questions for Your Next Doctor’s Appointment

Walk into your appointment with specific questions. It will get you further than walking in with general frustration, understandable as that frustration is.

Can I stay on a patch, whether through a different manufacturer, a different schedule, or a different strength?

If I do need to switch, what dose is equivalent to what I am on now, and which column of the table am I in?

Does my progestogen dose or schedule need to change as part of this switch?
Is there anything in my health history that makes oral estrogen a poorer choice for me specifically?

How long will it take to know whether a new dose is right, and what would count as the dose being wrong rather than a normal adjustment period?

What symptoms should trigger a call to the office rather than waiting it out?

What is the plan for switching back if and when patches return to full supply?

Do Not Stop Treatment Because Yours Ran Out

Running out of medication is not a reason to stop treatment. If you cannot reach your clinician and your supply is ending, call the office and say exactly that: you are out, or running out, of your medication. A gap in supply is a clinical problem that deserves a clinical response from your care team. It is not an inconvenience you are meant to quietly absorb on your own.

This guide is meant as a conversation tool, not a substitute for individualized medical care. The dose equivalencies here are approximations, not precise conversions, and product availability continues to change frequently. Verify current supply and current labeling directly with your pharmacist and clinician, and never change your dose, route of delivery, or progestogen without a new prescription from a clinician who knows your full history.
