Progesterone Dose for Menopause: Typical HRT Regimens and Safety Basics

For menopause hormone therapy, common oral micronized progesterone regimens are 100 mg daily when used continuously or 200 mg nightly for 12–14 days per 28-day cycle. The right dose depends on estrogen use, whether you have a uterus, bleeding pattern, symptoms, risks, and clinician guidance 1.

What is the usual progesterone dose for menopause?

Progesterone dose in menopause care is not one-size-fits-all. Guidelines commonly discuss 100 mg daily oral micronized progesterone for continuous use or 200 mg for 12–14 days per cycle for cyclic use, but these are reference regimens, not personal instructions 1.

Why 100 mg daily and 200 mg cyclic schedules are commonly discussed

Micronized progesterone is a form of progesterone made into tiny particles so it can be absorbed by mouth. In menopause hormone therapy, clinicians often discuss it alongside estrogen because estrogen can stimulate the endometrium, which is the lining of the uterus 1.

The North American Menopause Society lists oral micronized progesterone 100 mg daily as a continuous option and 200 mg for 12–14 days per cycle as a sequential option for endometrial protection when systemic estrogen is used 1. The FDA-approved Prometrium label also describes 200 mg daily for 12 days per 28-day cycle with conjugated estrogens for prevention of endometrial hyperplasia 2.

Why dose depends on the estrogen regimen and the uterus

The uterus question comes first. If a person has a uterus and uses systemic estrogen, progesterone or another progestogen is usually needed to lower the risk of endometrial hyperplasia, a precancerous thickening of the uterine lining 1.

The estrogen plan matters too. Higher estrogen exposure, persistent bleeding, perimenopause, and certain risk factors can change how a clinician thinks about dose, schedule, and follow-up 3.

Why is progesterone used with menopause hormone therapy?

Progesterone is used with systemic estrogen mainly to protect the uterine lining in people who still have a uterus. Unopposed estrogen can increase the risk of endometrial hyperplasia and endometrial cancer, and adding a progestogen lowers that risk 1.

How estrogen affects the uterine lining

Estrogen helps improve vasomotor symptoms such as hot flashes and night sweats, and it can also stimulate growth of the endometrium 1. When estrogen is given without enough progesterone-like effect in someone with a uterus, that stimulation can become unsafe over time 4.

How progesterone helps reduce endometrial hyperplasia risk

Progesterone changes the uterine lining from a growth state to a more stable, secretory state. In the PEPI trial, estrogen therapy without a progestin increased endometrial hyperplasia, while regimens that included a progestational agent reduced that excess risk 4.

When progesterone may not be needed after hysterectomy

If the uterus has been removed, progesterone is often not required for endometrial protection because there is no endometrium to protect. There are exceptions, so surgical history and the reason for hysterectomy still matter in a clinical review 1.

What is the difference between continuous and cyclic progesterone dosing?

Continuous progesterone dosing means progesterone is used every day with estrogen. Cyclic progesterone dosing means progesterone is used for part of a cycle, often 12–14 days, and the difference usually shows up in bleeding pattern 1.

Continuous combined therapy in postmenopause

Continuous combined therapy pairs estrogen and a progestogen on an ongoing basis. It is often discussed for postmenopause because the goal is usually no scheduled bleeding, although spotting or irregular bleeding can happen, especially early in therapy 1.

Cyclic or sequential therapy in perimenopause and early menopause

Cyclic therapy gives progesterone for part of the month. This approach may be used when a person is still having some ovarian cycling or when a clinician wants a planned withdrawal bleed after the progesterone phase 1.

Expected bleeding differences by schedule

Bleeding patterns are one of the most useful clues during follow-up. Scheduled bleeding can happen with cyclic therapy, while unexpected bleeding after menopause or heavy, persistent, or new bleeding needs clinician evaluation 3.

Is 100 mg or 200 mg progesterone more common for menopause?

100 mg and 200 mg progesterone are both common numbers because they belong to different schedule concepts. The 100 mg figure is commonly discussed for continuous oral micronized progesterone, while 200 mg is commonly discussed for cyclic use 1.

100 mg nightly as a common continuous regimen

NAMS lists 100 mg oral micronized progesterone daily as a continuous regimen used with systemic estrogen 1. Oral micronized progesterone can cause sleepiness or dizziness, which is one reason bedtime use is often discussed in clinical care and product labeling 2.

200 mg nightly for 12–14 days as a common cyclic regimen

NAMS lists 200 mg oral micronized progesterone for 12–14 days per cycle as a sequential regimen 1. The FDA-approved Prometrium label describes 200 mg daily for 12 days per 28-day cycle for prevention of endometrial hyperplasia in postmenopausal women receiving conjugated estrogens 2.

Why higher estrogen doses or bleeding concerns may change the plan

A clinician may reassess progesterone if estrogen dose changes, bleeding continues, side effects are hard to tolerate, or risk factors are present. Abnormal uterine bleeding evaluation can include history, exam, ultrasound, endometrial sampling, or other testing depending on age and risk 3.

What forms of progesterone are used in menopause care?

Progesterone can be used in several forms, but the evidence and labeling differ by route. Oral micronized progesterone has the clearest menopause endometrial-protection role, while compounded creams, injections, vaginal products, synthetic progestins, and levonorgestrel IUDs are handled differently 1.

Oral micronized progesterone and Prometrium

Prometrium is an FDA-approved oral micronized progesterone product with labeling for prevention of endometrial hyperplasia in postmenopausal women with a uterus who are receiving conjugated estrogens 2. Oral micronized progesterone is also the form most often referenced when people ask about 100 mg vs 200 mg menopause regimens 1.

Vaginal progesterone and endometrial targeting

Vaginal progesterone can deliver progesterone closer to the uterus, but many vaginal progesterone products are labeled for fertility-related uses rather than menopause hormone therapy. When used in menopause care, route and endometrial protection should be reviewed by a clinician 5.

Progesterone creams and absorption limits

Progesterone creams can be appealing because they are topical, but blood levels and endometrial effects may be less predictable than with oral regimens. Professional guidance has warned that compounded hormone therapy can have variable absorption and limited safety and efficacy data compared with FDA-approved products 6.

Synthetic progestins and levonorgestrel IUD options

Synthetic progestins, such as medroxyprogesterone acetate, are not identical to micronized progesterone, even though they can act on progesterone receptors. A levonorgestrel intrauterine device may also provide endometrial protection in some care plans, but this use and timing should be clinician-guided 1.

How should patients think about progesterone side effects?

Progesterone side effects are often manageable, but they matter. The FDA label for oral micronized progesterone reports dizziness, headache, breast tenderness, bloating, mood changes, and sleepiness-type effects, and it warns about risks that require medical review 2.

Sleepiness, dizziness, and why bedtime dosing is often used

Oral micronized progesterone can cause dizziness or drowsiness in some people. The Prometrium label cautions that it may cause transient dizziness and drowsiness and that patients should use caution with driving or machinery if affected 2.

Bloating, breast tenderness, mood changes, and bleeding

Other possible effects include bloating, breast tenderness, headache, mood symptoms, and bleeding changes 2. These symptoms do not always mean the dose is wrong, but they are worth tracking so the clinician can adjust the plan if needed.

When side effects or bleeding should prompt clinician follow-up

New bleeding after menopause, heavy bleeding, bleeding after sex, severe dizziness, chest pain, shortness of breath, leg swelling, severe headache, jaundice, or concern for pregnancy should be evaluated promptly. ACOG notes that postmenopausal bleeding requires timely assessment to rule out endometrial cancer and other causes 3.

How does progesterone treatment work at Chia?

At Chia, progesterone care starts online and is reviewed by a licensed US provider. We offer progesterone cream and injection, with plans currently starting at $109/mo, and we also offer an HRT for Women protocol that includes Estradiol Oral + Progesterone IR.

Your visit begins with a health questionnaire covering symptoms, menopause stage, uterus status, bleeding history, medications, and risk factors. A prescription is never guaranteed; our providers prescribe only when clinically appropriate after reviewing your health information.

When prescribed, Chia medications are compounded in the US by state-licensed 503A pharmacies and shipped to your door. Patients can message the care team through the patient portal between visits as dosing is guided and adjusted over time.

Because estrogen and progesterone decisions are connected, our providers review both sides of the plan. If estrogen is part of care, you can also read about Chia’s estradiol options before starting the online eligibility quiz.

How do clinicians decide whether a progesterone dose is right?

Clinicians decide whether a progesterone dose is right by looking at symptoms, bleeding, estrogen exposure, medical history, and follow-up response. A plan that fits one person at 100 mg may not fit another person using a different estrogen dose or route 1.

Symptoms, bleeding pattern, age, menopause stage, and medical history

Perimenopause, menopause, and postmenopause are not the same hormone setting. Irregular ovarian activity in perimenopause can make bleeding harder to interpret, while new bleeding after menopause needs a more urgent evaluation pathway 3.

Estrogen dose and route

Systemic estrogen includes oral, transdermal, and some other routes that affect the whole body. Local low-dose vaginal estrogen for genitourinary symptoms is different, and NAMS notes that a progestogen is generally not indicated with low-dose vaginal estrogen, although bleeding still needs evaluation 1.

Contraindications and risk review

Risk review includes personal history of breast cancer or other hormone-sensitive cancer, blood clots, stroke, heart disease, liver disease, unexplained vaginal bleeding, pregnancy possibility, and medication interactions. The Endocrine Society guideline recommends individualized menopause hormone therapy decisions based on symptoms, baseline risks, and patient preferences 7.

Follow-up and dose adjustments over time

Follow-up is not just about symptom relief. It also checks bleeding pattern, side effects, blood pressure, risk changes, and whether the benefit-risk balance still makes sense over time 1.

What questions should you ask a clinician before starting progesterone?

Before starting progesterone, ask practical questions that connect your uterus, estrogen plan, bleeding pattern, and side effect risk. The goal is not to find the lowest number; it is to find a plan with appropriate endometrial protection and tolerability 1.

• Do I need progesterone based on whether I have a uterus and whether I use systemic estrogen?
• Is my estrogen route systemic or local, and how does that affect progesterone need?
• Would a continuous or cyclic schedule fit my menopause stage and bleeding pattern better?
• What bleeding is expected, and what bleeding should I report right away?
• What side effects should I watch for, especially sleepiness, dizziness, mood changes, breast tenderness, or bloating?
• Do I have any contraindications, such as unexplained bleeding, hormone-sensitive cancer history, blood clots, liver disease, or pregnancy possibility?
• How will we follow up and adjust the plan over time?
