Micronized Progesterone Dosage:
100mg vs 200mg for HRT
The short answer
Micronized progesterone 100mg vs 200mg is usually a difference in schedule, not strength.100mg is typically taken every day (a continuous plan that aims for no scheduled monthly bleed). 200mg is typically taken for about 12–14 days a month (a cyclic plan that brings a monthly bleed). The right one depends on your exact product, your estrogen dose, and the plan your prescriber is following.
Here’s what almost no page tells you: the same medicine comes with differentofficial instructions depending on the product and the country. That’s the real reason two women can both be doing it “right” on completely different numbers — and why a quick search leaves you more confused than when you started.
This page is for you if…
You’ve been prescribed oral micronized progesterone as part of menopause HRT and you want to understand what your 100mg or 200mg actually represents — and what to verify before your next appointment.
This page is not for you if…
You’re using progesterone for pregnancy or fertility, trying to pick a dose on your own, using a compounded progesterone cream, or dealing with a new or frightening symptom right now. Those need your prescriber or pharmacist — not an article.
100mg vs 200mg micronized progesterone: the quick comparison
| 100mg usually represents | 200mg usually represents | What can change the answer |
|---|---|---|
| A continuous plan — taken every day — aiming for no scheduled monthly bleed. It’s the standard continuous dose in U.K. menopause guidance and the progesterone dose inside the FDA-approved combination capsule BIJUVA. | A cyclic (sequential) plan — taken 12–14 days a month — usually followed by a monthly bleed. This is the dose printed on the U.S. standalone progesterone label. In some higher-estrogen plans, 200mg is taken daily instead. | Your exact product (U.S. generic, Prometrium, BIJUVA, Utrogestan), your estrogen dose and route, whether your plan is continuous or cyclic, your country’s prescribing guidance, and your prescriber’s written instructions. |
This table describes common situations. It is not a dosing recommendation for you specifically.
Our one honest admission, up front: we can’t tell you whether 100mg or 200mg is right for you — and any page that pretends to is guessing. The good news is that’s exactly why this page is worth your time. Instead of a fake answer, we hand you the map to recognise your own situation and the precise questions that get you a real answer from your prescriber in a single conversation.
What we actually verified for this page
We verified:

A few quick definitions
- Micronized progesterone
- — the hormone progesterone ground into very fine particles so your body can absorb it better as a pill. In the U.S.: Prometrium or generic progesterone capsules. In the U.K.: Utrogestan (and other brands).
- HRT
- — hormone replacement therapy (also called menopause hormone therapy): taking hormones — usually systemic estrogen plus a progestogen for endometrial protection if you still have a uterus.
- The endometrium
- — the lining of your uterus. Endometrial hyperplasia is an abnormal overgrowth of cells in that lining; some forms can progress to cancer — which is the reason progesterone is in your HRT.
- Continuous combined HRT
- — estrogen and progesterone every single day; the goal is to be free of a scheduled monthly bleed.
- Sequential (cyclic) HRT
- — estrogen daily, but progesterone only part of the month; usually brings a monthly withdrawal bleed after you stop the progesterone each cycle.

What does micronized progesterone dosage 100mg vs 200mg actually mean?
For menopause HRT, 100mg and 200mg most often describe different schedules rather than competing versions of the same plan.A common pattern is 100mg taken every day (continuous) and 200mg taken for 12–14 days a month (cyclic). Your exact product, your estrogen dose, and your prescriber’s goal decide which one applies to you.
When you see “100mg vs 200mg,” your brain hears “weaker vs stronger.” But that’s usually not what’s going on. The number on the capsule tells you how much you take at once. The schedule tells you how often and for how many days. Without both, the comparison falls apart.
Most prescriptions land in one of three buckets:
100mg every night — a continuous plan
You take progesterone daily, alongside daily estrogen. The goal is to settle, over time, into no scheduled monthly bleed. This is the standard continuous dose in U.K. guidance, and it’s the progesterone dose built into the FDA-approved combination capsule BIJUVA.
200mg for 12–14 nights a month — a cyclic (sequential) plan
You take estrogen every day but progesterone only for part of the month. A monthly withdrawal bleed usually follows. This is the regimen printed on the U.S. standalone progesterone label.
200mg every night — also continuous, but in a different context
Some plans, especially with higher-dose estrogen, use 200mg daily. We’ll cover why below.
So “which is better, 100 or 200?” is a bit like asking “which is better, 1 pill or 2?” without saying of what, how often, or why. The honest answer: it depends on which plan your prescription belongs to.
Why does the schedule matter as much as the capsule strength?
Capsule strength is how much you take at a time; the schedule is how often and for how many days.Two plans with very different daily doses can add up to the same monthly total, and two plans with the same capsule can produce completely different bleeding. That’s why the number alone can’t tell you much.
How much progesterone is in a month? (The HRT Index calculation, June 2026)
| Pattern | The math | Nominal amount per 28 days |
|---|---|---|
| 100mg every day | 100 × 28 | 2,800mg |
| 100mg on days 1–25 | 100 × 25 | 2,500mg |
| 200mg for 12 days | 200 × 12 | 2,400mg |
| 200mg for 14 days | 200 × 14 | 2,800mg |
| 200mg every day | 200 × 28 | 5,600mg |
| 300mg for 12 days | 300 × 12 | 3,600mg |
Look at those numbers. 100mg every day and 200mg for 14 days both add up to the same monthly total — 2,800mg.That does not establish equal absorption, equal endometrial protection, equal effectiveness, equal bleeding control, or equal side effects. It’s arithmetic. It simply proves that “100 vs 200” with no schedule attached is the wrong question.
Continuous and cyclic plans also have different jobs. A cyclic plan is common earlier in the menopause transition and accepts a monthly bleed. A continuous plan is common later, once a woman wants to be free of a monthly bleed. Change only the capsule number and you can accidentally change both your monthly dose andyour bleeding pattern — which is one big reason this isn’t a do-it-yourself adjustment.
Which regimen does your prescription resemble?
A prescription taken every night usually resembles a continuous plan; one taken for a defined 12–14 day window usually resembles a cyclic plan.“Usually” is doing real work in that sentence — your exact product, country, estrogen dose, and your clinician’s written instructions are what actually decide it.
Find yourself here:
You take 100mg every night
Looks like a continuous plan. It matches the standard continuous dose in U.K. guidance and the progesterone dose inside FDA-approved BIJUVA. Just don't assume it's the U.S. standalone label's regimen — it isn't.
You take 200mg for 12–14 nights a month
Looks like a cyclic plan, and you'll likely have a monthly bleed after the progesterone nights. This matches the U.S. standalone label and the NHS's day-15-to-26 schedule for Utrogestan.
You take 100mg on days 1–25
A specific U.K./Utrogestan instruction — not a universal regimen. The NHS describes it for women who haven't had a period for 6–12 months or more.
You take 200mg every night
May reflect a higher estrogen dose, an effort to manage bleeding, or another reason specific to you. You can't reverse-engineer the 'why' from the dose alone — ask.
Your bottle and your patient portal disagree
This happens, and it's unsettling. Don't improvise. Photograph the bottle, note the manufacturer, call the pharmacy, and ask your prescriber to confirm in writing whether your plan is continuous or cyclic and which exact days to take it.

Match my full HRT situation → Find My HRT PathIs 100mg of micronized progesterone enough to protect the uterus?
For many women on lower- or medium-dose estrogen, 100mg taken every day is a guideline-supported way to protect the uterine lining.In the U.S., 100mg daily as a standalone capsule is off-label, and how much protection you need rises with your estrogen dose. Your prescriber is the one who confirms it’s enough for you.
If you have a uterus and use systemic estrogen, you need a progestogen to protect the endometrium. Estrogen on its own makes that lining grow, and over time unopposed growth can lead to endometrial hyperplasia and, in some cases, cancer.
Here’s the benchmark from the U.S. standalone label. In a trial of 358 postmenopausal women with an intact uterus, followed up to three years, 200mg of progesterone taken cyclically — 12 days per 28-day cycle — alongside conjugated estrogens 0.625mg daily produced endometrial hyperplasia in about 6% of women, compared with 64% on that estrogen alone.That’s a dramatic, real protective effect.
Two honest truths sit side by side:
Truth one: 100mg daily is a standard, supported dose
The British Menopause Society lists 100mg daily as its standard continuous-combined dose for women on low- or medium-dose estrogen. The FDA-approved combination capsule BIJUVA uses 100mg of progesterone taken every evening — in its 52-week endometrial-safety study, there was one case of hyperplasia in each BIJUVA dose group and none in the placebo group.
Truth two: as a standalone daily dose in the U.S., 100mg continuous is off-label
Off-label means an FDA-approved drug is being used in a dose, schedule, or situation the FDA hasn’t specifically approved. Doctors can prescribe off-label — it’s legal and common — but the FDA hasn’t reviewed that exact use. And the British Menopause Society is clear that the progesterone dose should be proportionate to the estrogen dose.
The practical takeaway: 100mg can absolutely be the right dose — in the right context, on the right estrogen dose. The way to know whether that’s youis to ask your prescriber: “Given my exact estrogen dose, is my continuous 100mg giving me adequate endometrial protection?”
Worried 100mg might not be enough for your estrogen dose? That’s the single best thing to pin down before you change a thing. Turn it into a question you can ask directly — build your consult question list with the Regimen Decoder →
How does your estrogen dose or patch strength change the answer?
Menopause guidance treats endometrial protection as proportionate to your estrogen dose— more estrogen generally means your prescriber wants more progestogen cover, not the same or less. The evidence gets thinner at high estrogen doses, so a stronger patch or higher gel dose is a reason to talk to your prescriber, never a reason to adjust your own progesterone.
The British Menopause Society puts it plainly: the progestogen dose should be proportionate to the estrogen dose. Its standard continuous dose is 100mg daily (or 200mg cyclically) with low- or medium-dose estrogen — and for higher estrogen exposure, it lists stepping up to 200mg daily continuous, or 300mg for 12 days.
It’s worth seeing how the U.K. guidance groups estradiol patchstrengths, because it shows how the thinking works. (This is a U.K. framework — don’t apply it to your gel or pill.)
| Estradiol patch strength | U.K. category |
|---|---|
| 25, 30, or 37.5 micrograms | Low |
| 40, 50, or 75 micrograms | Medium |
| 100 micrograms | High |
The same guidance treats gels and oral estrogen separately, so don’t try to translate a patch number onto a different product.
And here’s the honest limit, stated by the guideline itself: at high estrogen doses, the ideal progesterone dose is genuinely uncertain — the dose-specific evidence is limited. That’s not a gap we can paper over with a confident number.
If your estrogen recently went up, bring these four questions:
- “Did my estrogen move into a higher dose category?”
- “Does my current progesterone schedule still match the evidence you’re using?”
- “What bleeding pattern should make me call you?”
- “When will we review this change together?”
When do you switch from a cyclic plan to a continuous one?
Many women start on a cyclic plan (with a monthly bleed) and later move to a continuous plan to be free of bleeding.U.K. guidance notes that after at least a year of HRT, a woman who wants to stop the monthly bleed can try switching to a continuous combined regimen — a change to make with your prescriber, not on your own.
If you’re earlier in menopause, a cyclic 200mg plan with a planned monthly bleed is common. As you move further past your last period, a continuous 100mg plan that aims to be bleed-free is often the goal. The timing of that switch is individual — it depends on how long it’s been since your last period and how your body is responding — so it’s a conversation to have at a review, not a swap to make from the medicine cabinet.
Why do the FDA label, BIJUVA, the BMS, and the NHS all seem to disagree?
They aren’t answering the same question. The U.S. standalone label, the FDA-approved BIJUVA combination capsule, U.K. professional guidance, and U.K. patient instructions for Utrogestan each describe a different product or practice. Once you see which is which, the apparent contradiction turns into a simple map of contexts.
The HRT Index Regimen Map (June 2026)
| Source / context | Product & place | What it says for endometrial protection | Evidence window | What kind of statement it is |
|---|---|---|---|---|
| U.S. standalone progesterone label | Prometrium / U.S. generics | 200mg at bedtime, 12 days per 28-day cycle, with daily conjugated estrogens 0.625mg in a postmenopausal woman with a uterus. (Also 400mg × 10 days for secondary amenorrhea.) | Up to 36 months in the label trial | FDA-approved labeling for that specific standalone product and estrogen |
| BIJUVA | FDA-approved estradiol + progesterone capsule, U.S. | 100mg of progesterone, paired with 0.5mg or 1mg estradiol, once every evening with food. No 200mg version exists. | Up to 52 weeks (about 1 year) | FDA-approved, but the evidence belongs to BIJUVA as a complete fixed product — not automatically to separately prescribed estrogen + progesterone |
| British Menopause Society | U.K. professional guidance | 100mg daily (continuous) or 200mg for 12–14 days (cyclic) with low/medium estrogen; step up to 200mg daily or 300mg for 12 days with high-dose estrogen. | Cites trials up to ~5 years for the cyclic dose | U.K. clinical guidance — evidence-based, but not U.S. FDA labeling, and the high-dose step-up is pragmatic |
| NHS Utrogestan instructions | Utrogestan, U.K. patient info | 200mg on days 15–26 of a 28-day cycle; or 100mg on days 1–25 if you haven't had a period for 6–12+ months; sometimes daily. | Patient-instruction guidance | U.K. product-specific patient instructions |
Read across that table and the puzzle solves itself. A U.S. label, an FDA-approved combo product, a U.K. clinical guideline, and a U.K. patient leaflet are four different things. They’re not contradicting each other — they’re describing different situations. Your job (with your prescriber) is simply to know which one your prescription belongs to.
The instruction that proves you can’t mix products: food
Want the cleanest example of why you must never copy one product’s instructions onto another? Look at when to take it relative to food:
| Product | What its source says about food |
|---|---|
| BIJUVA | Take each evening with food. |
| NHS Utrogestan | Take at bedtime, at least 2 hours after food. |
| U.S. standalone progesterone label | Notes that food increased how much drug you absorb (studied at 200mg) — a finding, not an instruction. |
Two products give opposite instructions — BIJUVA with food, Utrogestan away from food. Same drug, different advice, depending on the product. This is your reminder to check the leaflet for your product and ask your pharmacist.
Does 200mg cause more sleepiness or side effects than 100mg?
Higher doses produce higher average progesterone blood levels, and oral micronized progesterone can cause drowsiness and dizziness — so more grogginess on 200mg is plausible and often reported.But the official data measures blood levels, not sleepiness, so it can’t prove 200mg makes any given woman groggier than 100mg, and individual responses vary a lot.
Oral micronized progesterone is broken down by your liver into calming, sedative-like compounds (they act on the same brain system as some sleep and anti-anxiety medicines). That’s why it’s taken at night, and why the label warns about transient dizziness and drowsiness and says to be cautious driving or operating machinery.
Average progesterone blood levels by dose (U.S. label data)
| Daily dose | Average peak level (Cmax) | Average total exposure (AUC₀–₁₀) | Compared to 100mg |
|---|---|---|---|
| 100mg | 17.3 ng/mL | 43.3 ng·hr/mL | reference |
| 200mg | 38.1 ng/mL | 101.2 ng·hr/mL | about 2.2× peak, 2.3× total |
| 300mg | 60.6 ng/mL | 175.7 ng·hr/mL | about 3.5× peak |
Doubling the dose roughly doubles the average blood level. But this table measures exposure — how much progesterone ends up in your blood — notgrogginess rates. And the variation around these averages is enormous — bigger than the average itself. Two women on the identical dose can have very different blood levels and very different experiences.
Other things women commonly notice and wonder about: morning fog, dizziness, headache, breast tenderness, bloating, mood changes, spotting. Some are listed effects; some have other causes entirely. If something feels off, the move is to tell your prescriber, not to quietly change your dose and hope.
⚠️ One genuinely important safety note on ingredients
The U.S. Prometrium label, and the generic capsule we reviewed, both list peanut oil— these are not for anyone with a peanut allergy. Inactive ingredients can differ by manufacturer, so if you’re allergic to peanuts, flag it and ask your pharmacist to check your exact product.
What does bleeding mean on 100mg or 200mg?
It depends on whether your plan is cyclic or continuous, how long you’ve been on it, and whether the bleeding is expected or new. On a cyclic plan, a monthly bleed is usually planned. On a continuous plan, early spotting can settle but new or persistent bleeding needs review.
| Your plan | What’s often expected | What to report to your clinician |
|---|---|---|
| Cyclic (200mg, 12–14 days) | A monthly withdrawal bleed in the days after the progesterone phase | Bleeding much heavier, longer, or at a different time than your prescriber said to expect |
| Continuous (100mg or 200mg daily), first 3–6 months | Some irregular spotting while your body adjusts | Spotting that's heavy, or that isn't settling over time |
| Continuous, settled (after several months) | Little or no bleeding | Any new bleeding after you'd become bleed-free |
🛑 The line where this page stops being the right tool
New bleeding after you’d been bleed-free, heavy or prolonged bleeding, worsening bleeding, or bleeding outside the pattern your prescriber expects should not be managed by changing your own progesterone. Contact the clinician who manages your HRT. Severe symptoms can need prompt in-person care.
And please resist the obvious-seeming fix of “just take more progesterone.” Bleeding can have several causes, and bumping your dose can muddy the picture your clinician needs to figure out what’s actually going on.
Who may not need progesterone for endometrial protection?
The “you need progesterone” rule mainly applies when you use systemic estrogen and still have a uterus. A total hysterectomy, low-dose vaginal estrogen only, leftover uterine tissue, or a history of certain conditions can all change the answer.
Systemic estrogen + a uterus
The classic case where a progestogen (or another accepted protection strategy) is generally needed. The Menopause Society is clear that unopposed systemic estrogen here raises endometrial cancer risk.
After a hysterectomy
If your uterus has been removed, the usual endometrial-protection reason for progesterone changes. But 'hysterectomy' isn't always total — and leftover tissue, endometriosis, or a cancer history can mean you're still prescribed progesterone for a specific reason. Confirm why you're on it before stopping.
Low-dose vaginal estrogen only
Low-dose local vaginal estrogen has minimal whole-body absorption, and current guidance generally doesn’t require adding a progestogen just for endometrial protection with today’s low-dose vaginal products. A cancer history or other complexity still belongs with a clinician. (More on this in our vaginal estrogen guide.)
A hormonal IUD
A 52mg levonorgestrel IUD is another way some women protect the endometrium while on estrogen. We mention it as a different model, not a recommendation.
| Your situation | What we can fairly say | Your next step |
|---|---|---|
| Uterus + systemic estrogen | Progesterone / endometrial protection is usually relevant | Verify your exact regimen |
| Total hysterectomy | The standard protection reason may not apply | Confirm the individual reason you're on it |
| Low-dose vaginal estrogen only | Different from systemic estrogen; long-term endometrial data is limited | Confirm product and risk history; report any bleeding |
| Unclear surgical history | We can't infer your anatomy | Ask your clinician or get your operative record |
| Cancer or complex history | General rules aren't enough | Specialist-led discussion |
Are oral, vaginal, and compounded progesterone interchangeable?
No. Route, formulation, absorption, and evidence all differ, so the same milligram number is not the same thing taken as a pill, used vaginally, or rubbed on as a cream. This matters most for compounded creams, which are not a reliable way to protect the uterus.
Oral capsules
The FDA-approved standalone products (Prometrium, U.S. generics) and the combination capsule BIJUVA. This is what this page is about.
Vaginal use of progesterone in HRT
Sometimes done, but using oral capsules vaginally is off-label, and U.K. guidance notes the evidence for the best vaginal approach is limited and absorption is uncertain. Not a switch to make on your own.
Compounded progesterone creams — a plain warning
The FDA does not verify a compounded drug’s safety, effectiveness, or quality before it’s sold. Menopause guidance is blunt that progesterone absorbed through the skin has variable absorption and is unlikely to provide sufficient endometrial protection. If you have a uterus and use estrogen, don’t count on a cream to protect your lining.
When you see a product mentioned anywhere, it helps to mentally tag it: FDA-approved, guideline-supported / off-label, or compounded / evidence uncertain. Those are not the same category, and “bioidentical” is not a free pass that erases the difference.
Can you take two 100mg capsules instead of one 200mg capsule?
Two 100mg capsules contain the same amount of progesterone as one 200mg capsule — but that arithmetic isn’t permission to swap.The product, manufacturer, inactive ingredients, timing, and your written prescription all still need a pharmacist’s or prescriber’s okay.
This comes up constantly, usually because a pharmacy is out of the 200mg, or you have 100mg capsules on hand. Here’s what to keep in mind:
- Inactive ingredients can differ. Some U.S. products, including the standalone capsules we reviewed, contain peanut oil; the 100mg version may also contain dyes the 200mg doesn’t. Ask the pharmacist to confirm your exact product.
- Don’t split a softgel. If your dose needs to change, that’s handled through the prescribed capsule strength, not by cutting capsules open.
- After a pharmacy substitution, ask: Is the active drug and route the same? Are the inactive ingredients different? Are the food instructions the same? Does the new label match my prescriber’s schedule?
- If you miss a dose, follow your product’s leaflet and ask a pharmacist when unsure. Don’t automatically double up — NHS guidance for Utrogestan explicitly says not to take two doses to make up for a missed one.
The theme, again: the number isn’t the whole instruction.
What questions should you ask before changing from 100mg to 200mg?
The most useful questions pin down your plan’s purpose, whether it’s on-label or guideline-supported, the bleeding pattern to expect, and the follow-up plan.The goal is to leave with a concrete list for your prescriber — not to change the dose yourself.
Your consult checklist:
- Do I still have a uterus, or any leftover uterine tissue?
- Is my progesterone plan continuous or cyclic?
- Exactly which days should I take it?
- What estrogen product, route, and dose are we balancing this against?
- Is my regimen on-label for my exact product, or is it guideline-supported / off-label — and what evidence are we using?
- What bleeding pattern should I expect?
- What bleeding or side effects should make me call you before my next visit?
- Does my exact product contain peanut oil, soy, or another ingredient I should know about?
- Should I take it with food, away from food, or some other way?
- When will we reassess my symptoms, bleeding, and the estrogen/progesterone balance?
Bring the bottle (or a photo): the front label, the manufacturer, the strength, the directions, and your estrogen product and dose. A two-minute photo saves a lot of guessing.
How much does micronized progesterone cost, and how do you get it?
Generic micronized progesterone is inexpensive— commonly in the range of about $15–25 for a month of 100mg capsules with a pharmacy discount, though the exact price swings with your pharmacy, location, quantity, coupon, and insurance. Because it’s a common, cheap, FDA-approved generic, your own doctor can prescribe and manage it.
Generic micronized progesterone typically runs in the low tens of dollars for a month of 100mg capsules with a free pharmacy coupon, against a higher list price (GoodRx figures, checked June 2026). The exact number genuinely moves around by pharmacy and location, so treat any single figure as a snapshot, not a fixed price.
The FDA-approved combination capsule BIJUVA costs more — on the order of $85 for 30 capsules with a discount at our June 2026 check, with actual cost varying by pharmacy, plan, and savings program. Generic progesterone is widely covered by insurance and Medicare plans, though your formulary and copay vary.
Because it’s a common, inexpensive, FDA-approved medicine, your own doctor can prescribe and manage it. If you don’t yet have a clinician who really knows menopause HRT, a menopause-literate telehealth provider can prescribe and manage FDA-approved progesterone too — but the dose decision is theirs to make with you, not something to shop for.

Neither dose is universally “better.”The real question is whether the strength, the number of days, your exact product, your estrogen exposure, your uterus status, your bleeding pattern, and how you feel all add up to a plan that fits you. That’s a conversation with your prescriber — and now you’re equipped to have a good one.
Find your situation:
- →You take 100mg every night: Likely a continuous plan. Confirm your product and that it suits your estrogen dose.
- →You take 200mg for 12–14 nights: Likely a cyclic plan, with a monthly bleed to expect.
- →You take 200mg every night: Ask whether it's about your estrogen dose, bleeding, or another goal.
- →Your estrogen just went up: Ask whether your progesterone was reassessed.
- →You feel very groggy, dizzy, or low: Don't change it yourself; call your prescriber or pharmacist.
- →You have unexpected bleeding: Don't treat the dose as the diagnosis; get it reviewed.
- →You've had a hysterectomy or use only low-dose vaginal estrogen: The usual 'you need progesterone' rule may not apply to you.
You came here worried you might be on the wrong number. The truth is calmer than that: 100mg and 200mg are both legitimate, and most prescriptions reflect a real, reasonable plan. We can’t validate yours from here or rule out a mix-up — so if your bottle and your instructions ever disagree, get it sorted before you change anything. But you don’t need to guess, and you definitely don’t need to experiment on yourself to feel certain. You just need to know which plan you’re on and ask two or three sharp questions. You can do that.

These answers cover the short follow-ups most likely to send you back to search — questions about products, schedules, your estrogen dose, side effects, bleeding, substitution, and route. Each one stands on its own.
- Is 200mg micronized progesterone a high dose for HRT?
- It’s a standard amount. 200mg is the usual cyclic dose (12 days a month), and it’s also the higher continuous dose used with high-dose estrogen. Whether “200mg” is “a lot” depends entirely on your schedule and your estrogen dose, so the number by itself isn’t worth worrying about.
- Is 100mg progesterone enough with an estradiol patch?
- It depends on your patch strength, your schedule, whether you have a uterus, and your risk factors. U.K. guidance scales progesterone to estrogen — lower-dose estrogen often pairs with 100mg continuous, while higher-dose patches may call for more. Don't classify yourself across products; ask your prescriber about your exact patch.
- Can 200mg progesterone be taken every day?
- Yes, in some clinician-directed plans — including higher-estrogen situations in U.K. guidance, where 200mg daily is the higher continuous dose. But daily 200mg isn't the default for everyone, and it's a decision your prescriber makes based on your estrogen dose and goals.
- Can 100mg be taken continuously in perimenopause?
- It's used continuously in some plans, but perimenopausal bleeding and natural hormone swings can affect which schedule fits. Your prescriber should define whether your plan is continuous or cyclic.
- Why did my clinician raise my progesterone after raising my estrogen?
- A common reason is keeping your endometrial protection proportionate to the higher estrogen dose. We can't know your specific reason, though — ask your prescriber what goal and evidence drove the change.
- Is 200mg better for sleep than 100mg?
- We won't say yes. Oral progesterone can cause drowsiness, and higher doses raise average blood levels, but that's a side effect, not a green light to self-dose for sleep. The dose used in sleep studies is 300mg at bedtime — a conversation to have with a clinician, not a DIY move.
- Does 200mg cause weight gain?
- The U.S. label lists both weight increase and weight decrease among effects reported after marketing, which means there's no clear, proven pattern — and nothing showing 200mg causes more long-term weight gain than 100mg. Short-term bloating or water retention is common and is different from actual long-term weight change.
- How many days a month is 200mg usually taken?
- In cyclic plans, often 12–14 days. The exact instructions vary by product: the U.S. label uses 12 days, while NHS guidance for Utrogestan uses days 15–26. Follow your product's directions.
- Do I need progesterone after a hysterectomy?
- Usually the standard endometrial-protection reason changes after a total hysterectomy — but the type of surgery, any leftover tissue, endometriosis, or cancer history can matter. Confirm with your clinician before stopping anything.
- Do I need progesterone with vaginal estrogen?
- Low-dose local vaginal estrogen is different from systemic estrogen, and current guidance generally doesn't require a progestogen just for protection with today's low-dose vaginal products. Your product, dose, and history still matter, and any unexpected bleeding needs evaluation, so confirm it.
- Can I take two 100mg capsules instead of one 200mg capsule?
- Only after your prescriber or dispensing pharmacist confirms it. The total milligrams match, but the product, inactive ingredients, and your written prescription still need to line up.
- Does micronized progesterone contain peanut oil?
- Some products do — including the U.S. Prometrium label and the generic capsule we reviewed. Don't assume they're all the same; ask your pharmacist to check your exact manufacturer, especially if you have a peanut allergy.
- What happens if I miss a dose?
- Follow your product's leaflet or ask a pharmacist. Don't automatically double up — NHS guidance for Utrogestan specifically says not to take two doses to make up for a missed one.
- Are Prometrium and Utrogestan interchangeable?
- Don't assume so. Country, licensing, formulation, inactive ingredients, and instructions can differ — including when to take them relative to food. BIJUVA requires taking with food; Utrogestan requires taking at least 2 hours after food.
- Can oral progesterone capsules be used vaginally?
- That's off-label, and U.K. guidance notes limited evidence and uncertain absorption for capsules used vaginally. It needs clinician direction, not a self-switch.
- Do progesterone blood levels tell me the right dose?
- No single blood number sets your dose. Your plan's purpose, your estrogen exposure, your bleeding, your product, and your risk factors all matter more than one reading.
- Does this guide apply to fertility or pregnancy?
- No. This page is only about micronized progesterone in menopause HRT.
Why women ask this
In menopause communities, this question rarely shows up as abstract pharmacology. It shows up in very human terms: is 100mg actually enough with my patch? How groggy will 200mg make me the next morning? Did my dose change for a reason I should understand?Those are exactly the right questions. (Comments and forums are useful for understanding what’s on women’s minds, but they aren’t medical evidence; one person’s experience on a dose can’t tell you what’s right or safe for you. That’s why this page leans on labels and guidelines for the facts.)
