What Kind of HRT Patches Are There? The 5 Types, in Plain English

What kind of HRT patches are there? In the U.S., menopause patches come in four core types — estrogen-only or estrogen-plus-progestin, each in a weekly or twice-weekly schedule — plus one special ultra-low-dose patch (Menostar) approved for osteoporosis prevention, not hot flashes. The fastest way to narrow them down is one question: do you still have a uterus?

We read the current FDA prescribing information for every patch named on this page to build the map below. Here’s the part most guides skip: the type that fits you usually has less to do with the brand name and more to do with your body and your routine. And one more thing worth knowing up front — as of June 2026, a national supply shortage is affecting some estradiol patches (more on exactly which, and what to do, near the end).

The five types at a glance

Before you go further: why a general answer can only take you so far

The right online HRT provider isn’t the same for every woman — it depends on your symptoms, your age and whether you have a uterus, your medication route preference (patch, pill, gel, or vaginal estrogen), your risk history, your insurance or cash-pay situation, and your state. Some situations belong with an in-person clinician first. Because a general answer can’t resolve those for you, use The HRT Index’s Find My HRT Path tool to match your situation to a best-fit care route — and to flag when in-person care should come first.

This page does the homework that comes before that. Read it, find your type, then let the tool match your specifics.

What kind of HRT patches are there? The U.S. types and FDA-approved products

HRT patches sort into two hormone families — estrogen-only and combination (estrogen plus a progestin) — and into two schedules, weekly or twice-weekly. Estrogen-only patches (like Climara, Vivelle-Dot, Dotti, Lyllana, and Minivelle) deliver estradiol on its own. Combination patches (Climara Pro and CombiPatch) carry a progestin in the same patch. Menostar is a separate, ultra-low-dose estrogen patch approved only to help prevent bone loss. (Source: FDA prescribing information via DailyMed.)

The HRT Index U.S. HRT Patch Map — Last verified June 2026

A national shortage is currently affecting some of these products — see “Are estradiol patches in shortage in 2026?” below for which, and what to do.

A few quick definitions so the rest of this page reads easily:

• Estradiol — the specific form of estrogen used in every U.S. menopause patch. It has the same chemical structure as the estradiol your ovaries made before menopause.
• Transdermal — “through the skin.” A patch is a transdermal product.
• Systemic — it reaches your whole body through your bloodstream.
• Vasomotor symptoms — the medical term for hot flashes and night sweats.
• Progestogen / progestin / progesterone — we untangle these next, because the words are not interchangeable.

A note on what’s not in this table:these are all FDA-approved, finished products. Compounded patches and creams (mixed by a pharmacy to order) are a separate category with a different regulatory status — we cover them honestly further down, and we never treat them as the same thing as an FDA-approved patch.

Do you need progesterone with an estrogen patch?

If you have a uterus and use systemic estrogen, a clinician generally adds a second hormone — a progestogen — to protect your uterine lining. If you’ve had a hysterectomy, you usually don’t need it. This isn’t a minor detail. Estrogen on its own can thicken the lining of the uterus, and over time that raises the risk of endometrial hyperplasia (an overgrowth of that lining that can lead to cancer). The progestogen keeps that lining in check. (Source: FDA prescribing information.)

If you’ve had a hysterectomy:an estrogen-only patch is the usual starting point, because there’s no uterine lining to protect. There are exceptions — for example, some women with a history of endometriosis — so your own history still matters.

If you still have a uterus: you generally need estrogen plus a progestogen. For patch-based therapy, two common approaches are:

1. One combination patch (Climara Pro or CombiPatch) that carries both hormones, or
2. An estrogen-only patch plus a separately prescribed progestogen (often a progesterone capsule).

If you’re not sure what was removed during a past surgery:don’t guess from whether you still bleed. Check your operative records or ask your clinician. A hysterectomy means the uterus was removed; removing one or both ovaries is a separate procedure (an oophorectomy) — it’s sometimes done during the same operation, but it’s not the same thing. The difference can change your plan.

Progesterone, progestin, and progestogen are three different words

This is the single most common mix-up we see, and it’s worth thirty seconds:

• Progestogen is the umbrella term for the whole hormone class.
• Progesterone is the natural hormone your body makes — and the name of certain medications (like micronized progesterone capsules).
• Progestin is a synthetic member of the class.

Why it matters here: the U.S. combination patches contain progestins, not micronized progesterone. Climara Pro uses levonorgestrel; CombiPatch uses norethindrone acetate (Source: FDA prescribing information via DailyMed). So if your clinician specifically wants you on micronized progesterone, a combination patch won’t deliver that — you’d more likely use an estrogen-only patch plus a separate progesterone capsule. Not better or worse. Just different.

The honest part: there is no single “best” HRT patch

We’ll say it plainly, because anyone who tells you otherwise is selling something: no patch type wins for everyone.A combination patch is genuinely convenient — two hormones, one product, one routine. The trade-off is that the two hormones come in a fixed ratio, so your clinician can’t dial the estrogen and the uterine-protection up or down independently.

If that flexibility is your priority, a combination patch is notyour best fit — an estrogen-only patch plus a separately prescribed progestogen gives your clinician more room to adjust each hormone. Both are real options. The right one depends on you — which is the whole reason we built a tool instead of just crowning a “winner.”

What is the difference between an estrogen-only and combination HRT patch?

An estrogen-only patch carries estradiol and leaves any needed uterine protection to a separate product. A combination patch carries estradiol plus a progestin in one fixed-ratio patch — simpler to use, but less adjustable. The choice usually follows your uterus status first, and your preference for simplicity versus flexibility second.

Does a combination patch contain progesterone?No — it contains a progestin (levonorgestrel in Climara Pro, norethindrone acetate in CombiPatch), which acts like progesterone in protecting the uterine lining but is not the same medication as micronized progesterone. If your clinician wants you specifically on progesterone, you’ll likely take it separately.

Are HRT patches changed once a week or twice a week?

Both schedules exist, and they’re not interchangeable. Weekly patches stay on for 7 days; twice-weekly patches are replaced every 3 to 4 days. Always follow the schedule on your specific product — not a generic “patch” rule. Weekly means fewer changes to remember. Twice-weekly patches are usually smaller. (Source: FDA prescribing information via DailyMed.)

A simple way to run a twice-weekly schedule is to pick two fixed days — say Monday and Thursday, or Tuesday and Friday — and stick to them.

Is one schedule more effective? Not on its own. Counting weekly changes tells you about convenience, not results. What actually matters is the hormone content, the labeled dose, how consistently you wear it, how your skin tolerates it, and your clinical situation.

What if the pharmacy gives you a different manufacturer?During a shortage this happens a lot. Ask your pharmacist to confirm the exact active ingredient, the strength, the change schedule (weekly vs. twice-weekly), the application instructions, whether the product is rated therapeutically equivalent, and whether your prescriber needs to authorize the switch. Matching only the number printed on the box isn’t enough.

What do the dose numbers mean? (0.025, 0.05, and “mg vs. mcg”)

On an estradiol patch, a number like 0.025 or 0.05 is the milligrams of estradiol the patch is labeled to deliver per day — not the total amount packed into the patch. Patches come in a range of strengths, clinicians typically start low and adjust to your symptoms, and you should never do your own math to switch products or cut a patch to change the dose.

The same delivery rate can be written in milligrams or micrograms — they’re just different-sized units (1 mg = 1,000 mcg):

Climara’s label lists the full set of weekly strengths above; twice-weekly patches commonly come in 0.025, 0.0375, 0.05, 0.075, and 0.1 mg/day. (Source: FDA prescribing information via DailyMed.)

Why do combination patches show two numbers?Because they carry two hormones. The first number is the estradiol dose; the second is the progestin dose. So CombiPatch’s “0.05 / 0.14” means 0.05 mg/day estradiol and 0.14 mg/day norethindrone acetate, and Climara Pro’s “0.045 / 0.015” means 0.045 mg/day estradiol and 0.015 mg/day levonorgestrel. You can’t compare those second numbers to an estrogen-only patch — they’re different hormones doing different jobs.

Is a higher number always stronger or better? No. More is not better; right for youis better — and that’s a clinician’s call based on your symptoms and history.

Are HRT skin patches systemic or local — and is a patch even right for your symptoms?

Menopause skin patches are systemic: estradiol crosses your skin into your bloodstream and travels through your whole body. Low-dose local vaginal estrogen is a different route that mainly acts where it’s placed. If your only symptoms are vaginal or urinary, a systemic patch may be more than you need — and a local option might be the better first conversation. (Source: The Menopause Society.)

What “systemic” means in practice: a systemic estradiol patch is FDA-approved for indications like moderate-to-severe vasomotor symptoms (hot flashes and night sweats).

What “local” means: low-dose vaginal estrogen (a cream, tablet/insert, or ring like Estring) targets the tissues of the vagina, vulva, and urinary tract. The medical name for those symptoms is genitourinary syndrome of menopause(GSM) — think vaginal dryness, irritation, pain with sex, and some urinary symptoms.

This might be the wrong page for you if your concerns are onlyvaginal dryness, pain during sex, or urinary urgency. In that case, a skin patch may not be the most targeted choice, and you’ll want to read our guide to vaginal estrogen instead. The Menopause Society notes that when GSM is the only issue and systemic therapy isn’t otherwise needed, low-dose vaginal estrogen is often the more appropriate route.

Which type of HRT patch might fit your situation?

No category is best for every woman, but a few questions narrow it fast: do you have a uterus, are your symptoms body-wide or vaginal-only, do you prefer one all-in-one patch or separately adjustable hormones, how often can you reliably change a patch, and can your pharmacy and insurance actually supply the exact product?

Here’s the logic we’d walk through (these are categories to discuss with a clinician — the clinician selects the actual product, strength, and regimen):

• No uterus (hysterectomy)? An estrogen-only patch is the usual starting point — weekly or twice-weekly are both options to raise. (Exceptions exist based on your history.)
• Have a uterus and want simplicity? A combination patch puts both hormones in one product. Discuss whether weekly (Climara Pro) or twice-weekly (CombiPatch) fits.
• Have a uterus and want flexibility? An estrogen-only patch plus a separately prescribed progestogen lets your clinician adjust each hormone on its own. More steps, more control.
• Vaginal or urinary symptoms only? Look at local vaginal estrogen first.
• Mainly worried about bone loss, not hot flashes? Menostar exists for that — but ask about the full range of bone-protection options, since a patch isn’t the only one.
• Skin reacts to adhesives, or patches won’t stay on? A clinician may discuss a gel or spray when adhesive problems make patches impractical.
• Not sure online care is even right for you? That’s exactly what our tool flags.

What is the difference between continuous and cyclic HRT regimens?

“Continuous” and “cyclic” (also called sequential) describe when you take estrogen and progestogen — not how often you change a patch. Continuous-combined therapy uses both hormones on an ongoing basis. A cyclic or sequential plan adds the progestogen during a set part of the cycle.

• “Continuous” does not mean one patch stays stuck on forever. You still change patches on schedule. It refers to the hormone pattern, not the adhesive.
• The regimen affects bleeding. Sequential plans are often linked with a predictable monthly bleed; continuous-combined often aims for no bleeding over time. Your clinician will tell you what to expect.
• Real products show this in their labels. Climara Pro is a continuous-combination patch; CombiPatch’s label describes both continuous-combined and continuous-sequential regimen concepts (Source: FDA prescribing information via DailyMed).

Quick vocabulary: weekly / twice-weekly = how often you replace the patch; continuous / cyclic = the hormone schedule; strength = the labeled daily dose; brand = the specific finished product and manufacturer.

Are estrogen patches safer than HRT pills?

The route can change part of the risk picture — but a patch is not risk-free. Because a patch absorbs through your skin instead of going through your stomach and liver first, research suggests it has lesseffect on blood-clotting factors than estrogen taken as a pill. That’s why route is part of the conversation specifically when a clinician is weighing the risk of venous blood clots (venous thromboembolism, or VTE). It does notmean a patch is broadly “safer for your heart,” and it doesn’t make estrogen right for everyone. (Source: ACOG; The Menopause Society.)

What “skipping the liver” can change. Swallowed estrogen passes through the liver before it reaches the rest of your body (this is called first-pass metabolism), which can nudge up certain clotting proteins and triglycerides. A patch largely bypasses that step. Major bodies including The Menopause Society and ACOG note that transdermal estrogen appears to have less effect on clotting markers than oral estrogen.

What a patch does not erase.Estrogen — by any route — still isn’t right for everyone. For a fuller look at the trade-offs, see HRT benefits and risks.

Who should start with an in-person clinician, not an app.If you have unexplained vaginal bleeding, a complex cancer history, a past blood clot or stroke, significant liver disease, an uncertain surgical history, any chance of pregnancy, or symptoms that need a physical exam — please begin with an in-person visit.

What side effects and warning signs can HRT patches cause?

Estrogen patches commonly cause skin irritation at the patch site, breast tenderness, headache, nausea, bloating or fluid retention, and irregular spotting or bleeding — most of which often settle over the first weeks. Exact side-effect rates differ by product. Always read the label for your specific patch. (Source: FDA prescribing information.)

Common, usually manageable effects (talk to your clinician if they persist or bother you): redness or itching where the patch sits, breast pain or tenderness, headache, nausea, bloating, mood changes, and spotting or irregular bleeding, especially in the first few months.

Call your clinician or seek care right away if you notice signs of a serious problem:

• Blood clot — pain, swelling, or warmth in a leg; sudden shortness of breath; chest pain; coughing up blood.
• Stroke — sudden numbness or weakness (especially on one side); a sudden severe headache; trouble speaking; vision or balance changes.
• Heart attack — chest pain or pressure, possibly spreading to the jaw, shoulder, or arm.
• Severe allergic reaction — swelling of the face, lips, or throat; trouble breathing.
• Sudden vision changes or loss.
• Any unexplained or persistent vaginal bleeding — this always deserves evaluation, because bleeding after menopause can be a warning sign of a problem with the uterine lining.

Situations where these patches generally aren’t used — or need careful evaluation first. Current FDA labeling lists categories such as: undiagnosed abnormal genital bleeding; known, suspected, or past breast cancer (where listed); other estrogen-dependent cancers; a current or past blood clot (DVT or PE); current or recent stroke or heart attack; known blood-clotting disorders; liver problems or liver disease; a known allergy to the product; and pregnancy. One nuance: a familyhistory of something like breast cancer or clots is a risk factor your clinician weighs — it’s not automatically the same as a personal contraindication.

How do you use a patch — and what if it falls off?

Most estradiol patches go on clean, dry skin on the lower belly or upper buttock, away from the breasts, with the spot rotated each time — but your exact product’s instructions always win.

The universal basics:

• Wash and dry your hands.
• Use clean, dry skin that isn’t irritated or broken.
• Skip lotion, oil, or powder on the spot — they can keep the patch from sticking.
• Use only the body areas your label approves, and never on or near the breasts.
• Rotate sites; don’t reuse the same patch of skin right away.
• Press firmly for the time your label says.
• Change it on your scheduled day.

What if it falls off?Follow your product’s instructions. Some labels let you press it back on or apply a fresh patch for the rest of the interval. What you should notdo is add an extra patch to “catch up” or change your timing on your own.

Can I cover it with tape or a bandage?Not every product’s label authorizes an overlay. Check your exact label or ask a pharmacist before covering a patch.

Can I cut a patch?Don’t — unless your exact product’s label and a clinician or pharmacist explicitly say that product can be cut.

Are estradiol patches in shortage in 2026?

Yes — but it’s uneven, not a total blackout. As of June 2026, a supply shortage tracked by ASHP affects some estradiol patch products and strengths, while other products are still listed as available. Demand has climbed sharply since the FDA’s 2025 warning change, running into a small number of manufacturers — when one has a delay, it’s felt nationally. (Source: ASHP drug-shortage tracking; NBC News, 2026.)

What to ask the pharmacy:

• Is my exact strength in stock?
• Which manufacturer do you have?
• Is the change schedule the same (weekly vs. twice-weekly)?
• Can you do a partial fill, or check another location?
• Does switching manufacturers need my prescriber’s approval, and will insurance cover the one you have?

What to ask the prescriber:

• If my exact patch stays unavailable, what’s my backup route?
• Should the prescription name a specific manufacturer?
• Which substitutions keep the same schedule and dose intent?
• What should I do before my current supply runs out?

What not to do.Don’t stretch your patches or skip days to ration them without your clinician’s say-so. Don’t double up. Don’t change your interval on your own. Don’t use a dose-conversion chart to switch yourself between products. And don’t assume a compounded patch is an equal swap — it isn’t (next section).

How do I read an HRT patch prescription and compare brands?

The smartest way to compare patches isn’t by brand familiarity — it’s by the details on the prescription. Hormone content, daily dose, schedule, what it’s approved for, your uterus plan, manufacturer, insurance coverage, and local stock tell you far more than a name you half-recognize.

Questions to bring to your clinician

• Which category are you recommending for me, and why?
• Does my uterus status change the plan?
• Is this estrogen-only or combination?
• Why this schedule?
• What does the number on my prescription mean?
• What should I do if the pharmacy switches manufacturers?
• What’s the backup if my product is unavailable?
• What symptoms or side effects should make me call you?
• When will we reassess whether this is still working?
• Are any of my symptoms better treated with a local vaginal option?

Questions to bring to your pharmacist

Keep these focused on the product, not your medical plan: Is the active hormone, labeled dose, and schedule the same as what was prescribed? Is the manufacturer changing? Is the substitute rated therapeutically equivalent? Does a substitution need prescriber approval? Will my insurance cover what you have in stock?

A word on substitutions.Brand name, generic manufacturer, the NDC number, schedule, patch size, application instructions, and FDA therapeutic-equivalence status are all separate fields. Two products can share the same active hormone and dose and still differ in size or adhesive. Don’t assume “same drug” means “switch without thinking” — confirm the fields above with your pharmacist.

Are compounded HRT patches another type?

The five types in our table are all FDA-approved, finished products. Compounded hormone preparations — mixed by a pharmacy to order — are a separate category, and they should never be presented as equivalent to an FDA-approved patch. Compounded drugs are not FDA-approved; the FDA does not verify their safety, effectiveness, or quality before they’re marketed. (Source: FDA, Human Drug Compounding.)

To be clear and fair: compounding has legitimate uses — for example, when someone is allergic to an ingredient in a commercial product, or needs a form that isn’t made commercially. But for routine menopause hormone therapy, professional guidance leans against it when an approved option fits. ACOG advises against the routine use of compounded bioidentical menopausal hormone therapy when FDA-approved products can meet a patient’s needs.

One myth worth retiring: you do notneed a compounded product to get a hormone that matches your body’s own. The estradiol in FDA-approved patches already has the same chemical structure as the estradiol your body made (Source: FDA). So “matches your body’s hormone” and “compounded” are not the same thing — an FDA-approved patch is structurally identical estradiol that has also been through FDA review.

How did The HRT Index verify this guide?

This page uses The HRT Index Verification Standard: every patch ingredient, schedule, dose strength, and approved use was checked against current FDA prescribing information, and the regulatory and shortage details were dated separately. Our editorial contribution is the classification and the decision framework — not a claim that one patch is best for everyone.

Who made it. The HRT Index Editorial Team — the independent menopause HRT decision layer for women. No invented author, no invented “medically reviewed by” credit, and no made-up first-person experience. We say plainly when something is editorial research rather than clinical review.

How we made it.We pulled product facts from FDA labels on DailyMed; confirmed the February 2026 FDA labeling update against the FDA’s own list; checked national shortage information from ASHP; and drew medical context from The Menopause Society and ACOG.

The five pillars behind everything we publish. When we evaluate providers, we use exactly five, in this order: clinical legitimacy, care quality, medication fit, price transparency, and access.

What we did not verify:your eligibility, your dose, your pharmacy’s stock, your copay, typical results, whether one brand is better for you than another, or how each patch feels to wear. Those are yours to confirm with a clinician and pharmacist.

Frequently asked questions about HRT patches

These answers clear up the terminology, schedule, and prescription questions that usually send people back to searching. They’re general and educational — your specific instructions and treatment decisions should come from your product’s label, your pharmacist, and your prescribing clinician.

You’ve found your type — here’s the next step

You came in asking what kind of HRT patches are there, and now you’ve got the map: two hormone families, five practical types, the uterus question that drives most of the decision, the dose numbers decoded, the warning signs to watch for, and a clear-eyed view of the 2026 shortage. That’s more than most women walk into a consult with.

The last mile is matching all of that to yourbody, your state, and your coverage — and figuring out whether to start online or in person.

The HRT Index is the independent menopause HRT decision layer for women. This page is educational and is not medical advice. FDA-approved and compounded options are labeled distinctly throughout, and compounded therapy is never implied to be safer than, more natural than, or equivalent to FDA-approved medication.
