Dear readers,
Your pharmacy cannot get your estradiol patch. Neither can mine, most weeks.
Here is what matters. There are four ways to get estradiol into your bloodstream. Three of them are not a patch. None of them is a pill. And you can start one this month.
You do not need to stop. I have had women arrive having gone without for six weeks, assuming there was nothing to be done, sleeping badly and wondering why they feel like a stranger to themselves. There was something to be done the entire time.
What is happening
A supply problem, not a safety problem. Nothing was recalled. The patches are fine. There are not enough of them.
On November 10, 2025, the FDA asked manufacturers to strip the boxed warnings off menopausal hormone therapy. The cardiovascular language, the breast cancer language, the probable dementia language, and the old instruction to use the lowest dose for the shortest time. Twenty-three years of fear, formally revised.
Women moved. Patch prescriptions went from roughly 594,000 in June 2024 to about 1.6 million by May 2026. Nobody built for a 162 percent increase, and patches are hard to make. Adhesive chemistry and drug-release membranes do not scale up in a quarter.
One detail that will show up on your pharmacy bill. Pharmacists list more than a dozen patch products as short. The FDA has not added them to its shortage database, on the reasoning that national supply and national demand still roughly balance even when your pharmacy’s shelf is empty. That designation is what loosens the rules for compounding pharmacies and pushes insurers to cover alternatives. Without it, you may be told your substitute is not covered.
Estimates for catching up run a year or more. No manufacturer has published a date I would trust.
Why not a pill
Your liver.
Swallowed estradiol passes through the liver before it reaches the rest of you, and the liver answers by producing more clotting factors. Estradiol through skin, through vaginal tissue, or from an oil depot in muscle skips that entirely. Fifteen observational studies put the clot risk on oral at about 1.6 times transdermal.
Four routes bypass the liver. I am not moving anyone onto the one that does not.
Some of my patients do take oral estradiol. They arrived on it, or they weighed the options and preferred a pill. If that is you and it is working, nothing here is a summons to change. But a shortage is not a reason to start.
If an urgent care or a covering physician offers you a pill to bridge the gap, call us first.
The patch
What it does well. Steady levels, applied weekly or twice weekly, strengths from 0.025 to 0.1 mg per day, and the cheapest option with insurance. The best studied of the four.
What it costs you now. The hunt. Pharmacies tell patients what is physically on the shelf that morning. They will not run inventory searches for a doctor’s office, and no clinic can call thirty pharmacies for you. This part is yours.
If you hunt. Independents first, because they check while you are on the phone. Ask what estradiol patches they have today, any strength, any brand. Two 0.025 patches make a 0.05. The weekly brand is often sitting there when the twice-weekly one is gone. Call us with the pharmacy that has product and we send it that day, written generically, ninety days when we can.
What I would rather you do. Look hard at the next three now, while you still have patches in the drawer. Not after eight weeks of phone calls and a month of going without. These are not consolation prizes. For some of you they are better than what you were on.
One practical note. Ask your pharmacist before cutting a patch. Most are matrix and tolerate it. Some are destroyed by it.
Gels, sprays, and creams
Compounded cream. A compounding pharmacy makes estradiol in a cream base, applied daily to the inner forearm or thigh. Any dose you need. No adhesive, so no rash and nothing peeling off in the shower. Often available when nothing else is, and cash prices are usually modest.
What it costs you. Compounded product is not FDA-approved, so nobody verifies potency batch to batch. Which pharmacy you use matters, and I send patients to compounders I know. Skin absorption varies between people and by application site. And it transfers. Children, partners, and pets absorb what is on your skin. Cover the site with clothes, wash your hands.
How I dose it. Your symptoms and a serum estradiol level.
Estradiol cypionate injection
What it is. An oil depot, marketed as Depo-Estradiol. The label says 1 to 5 mg intramuscularly every three to four weeks. I use smaller doses weekly or every ten days, usually subcutaneous, because monthly dosing gives a high peak and a miserable trough with symptoms back days before the next dose. That schedule is off-label and well established.
What it does well. Absorption does not depend on your skin. Nothing daily, nothing to fall off, nothing to transfer to your family, and it is inexpensive. If you have never absorbed transdermals well, and some of you never have, this may be the best option you have had.
What it asks of you. A needle, which we teach in one visit. And dates. A level drawn the day after an injection means something completely different from one drawn the day before the next. Write them down.
One note. Estradiol valerate, the other injectable, has had its own supply problems this year. Cypionate is where I look first.
Femring
What it is. Estradiol acetate in a flexible ring, placed in the vagina, replaced every three months. Two strengths, 0.05 and 0.10 mg per day, producing serum levels around 41 and 76 pg/mL. Patch territory.
Femring is not Estring. I correct this almost weekly. Femring is systemic and treats hot flashes, night sweats, and vaginal symptoms together. Estring is local only and will do nothing for your sleep or your temperature. They are not interchangeable.
What it does well. Ninety days of steady levels with nothing to do in between. No adhesive, no daily ritual, no transfer, no needle. It treats the vaginal and urinary symptoms at the same time, which for many women is the complaint they were most embarrassed to raise.
What it costs you. Coverage varies and it can be expensive. Two strengths only, so no fine titration. Some women dislike insertion, and the ring can shift with straining. It comes out for intercourse and goes back after.
What does not change
If you have a uterus, systemic estrogen requires endometrial protection with progesterone. Every route on this page. Cream included. Injection included. Femring included.
Micronized progesterone at bedtime, which helps most women sleep. When we change your estrogen, your progesterone stays as it is unless I tell you otherwise. In the scramble to find any estrogen at all, this is the piece that gets dropped.
What to do
Start at two boxes left, not one.
Decide whether you are hunting or switching. Both are fine. Drifting is not, and drifting is what I keep seeing. Half looking, half hoping, and a month with nothing.
Hunting means you make the calls. Switching means you book now, while you still have product.
Send us any insurance denial instead of quietly paying cash.
Then recheck at six to eight weeks. Symptoms, and a level when it will change what we do. The dose that worked on a patch is an estimate in any other form, and that visit is what keeps a substitution from becoming undertreatment.
One last thing
Women waited more than twenty years for the labels to be corrected, for the science to be reconsidered, for permission to treat symptoms that were never trivial. The correction came. Hundreds of thousands of women acted on it. The supply chain was not ready for them.
You cannot fix that. You can stop treating one delivery method as the only one that counts.
Reach out at two boxes, not at zero. Nobody should lose a season of her life to sleeping badly because a factory could not keep up.
Reach out to our office at 703-866-4144 or schedule a free consultation with us and let’s get you sorted the right way.
Best wishes,
