Overview
The list of genuine contraindications to systemic hormone therapy is shorter than most people expect, and a number of things women are routinely refused for are not on it.
Both halves of that matter. Some women are given hormone therapy who should not be. Rather more are refused it who could have it.
| Genuine contraindications to systemic estrogen |
|---|
| Undiagnosed abnormal vaginal bleeding — investigate first, then reconsider |
| Known, suspected or previous breast cancer — an oncology decision, not a general one |
| Known or suspected estrogen-dependent cancer |
| Active or recent venous thromboembolism, or a known high-risk thrombophilia |
| Active or recent arterial disease — heart attack, stroke, angina |
| Active liver disease with abnormal liver function |
| Pregnancy |
| Untreated endometrial hyperplasia |
Several of these are temporary rather than permanent. Undiagnosed bleeding is investigated and the question reopens. Uncontrolled blood pressure gets controlled. Active liver disease may resolve. "Not now" and "not ever" are different answers, and they are frequently conflated.
And two things belong in every version of this page: the route changes several of these considerations, and local vaginal estrogen sits outside most of them because systemic absorption is minimal.
What is often mistaken for a contraindication
This section exists because the refusals are common and many of them are not supported.
Migraine, including migraine with aura. Frequently refused on the basis of contraceptive guidance, which concerns a different, higher-dose synthetic estrogen. Current menopause guidance generally does not treat migraine with aura as a contraindication, and transdermal is preferred. The full picture.
Controlled high blood pressure. Not a barrier. Uncontrolled hypertension is a sequencing issue — treat it, then reconsider. More.
Being over 60, or more than five years in. Arbitrary age and duration limits are not supported by current guidance. Starting after 60 is a different question from continuing past it. What the timing evidence says.
A family history of breast cancer. A consideration that enters the risk assessment, not an automatic exclusion. A personal history is a different matter.
Fibroids or endometriosis. Generally manageable rather than disqualifying, though they influence the choice of regimen.
Gallbladder disease. Relevant to route — oral estrogen increases gallstone risk more than transdermal — rather than disqualifying.
Diabetes. Not a contraindication; transdermal is often preferred.
Being a smoker. Increases cardiovascular and clot risk and is a strong reason to stop smoking. It is not by itself an absolute contraindication to transdermal therapy, though it changes the assessment.
If you have been refused for something on this list, it is worth asking on what basis.
Why the route changes several of these
The same mechanism runs through most of the risk conversation, and it is worth understanding once.
Oral estrogen passes through the liver at high concentration before reaching the rest of the body, and the liver responds — increasing clotting factor production, raising triglycerides, and affecting blood pressure regulation in some women.
Transdermal estradiol enters the general circulation directly and largely avoids those hepatic effects.
Which means several considerations that count against oral estrogen are considerably weaker against transdermal — clot risk most importantly, but also blood pressure, triglycerides and gallbladder risk. The route comparison in full.
So "you cannot have HRT" and "you should not have oral HRT" are different statements, and the second is much more often the accurate one.
Vaginal estrogen is a separate question
Worth its own section because it is the most commonly missed option.
Low-dose vaginal estrogen has minimal systemic absorption, which means most of the contraindications above do not apply to it in the same way. It is frequently appropriate for women who cannot take systemic hormone therapy.
Which matters because the symptoms it treats — dryness, discomfort with sex, urinary urgency, recurrent urinary tract infections — are progressive without treatment, unlike hot flashes.
A woman who cannot take systemic estrogen should still be asked about genitourinary symptoms, and frequently is not. What local treatment does. The breast cancer situation is its own conversation with its own guidance. More there.
What is available where systemic treatment is genuinely not appropriate
Non-hormonal prescription options for vasomotor symptoms, several with real evidence.
Cognitive behavioral therapy, with good evidence for reducing how much symptoms interfere with daily life.
Local vaginal estrogen, as above, in most cases.
The modifiable contributors — alcohol, smoking, room temperature, weight — which do more work when hormonal treatment is off the table. What helps with night sweats.
And treating what else is going on. Thyroid disease, iron depletion and sleep apnea produce overlapping symptoms and are treatable regardless. Why the panel matters.
Frequently asked questions
Who should not take HRT? The genuine contraindications are undiagnosed abnormal bleeding, known or suspected breast or estrogen-dependent cancer, active or recent clots or arterial disease, active liver disease, pregnancy and untreated endometrial hyperplasia. Several are temporary rather than permanent.
I was refused because of migraines. Is that right? Frequently that reflects contraceptive guidance rather than menopause guidance. Migraine with aura is not generally a contraindication to menopausal hormone therapy, and transdermal is preferred.
Does a family history of breast cancer rule me out? It enters the risk assessment rather than excluding you automatically. A personal history is a different situation requiring oncology input.
What if I have had a clot? Oral estrogen is generally avoided. Transdermal may be possible depending on the circumstances, with input from whoever manages your clotting history. More.
Can I still use vaginal estrogen? In most cases yes — systemic absorption is minimal, so most of these considerations do not apply in the same way.
Where this fits in your plan
The useful question is rarely "am I allowed." It is which route is appropriate, what needs treating first, and whether the reason you were refused still stands.
That takes a proper assessment — bleeding history, clot history, cardiovascular risk, blood pressure, personal and family cancer history — rather than a checklist applied at a distance. What we assess, and what hormone therapy with us involves.
We measure first. Then we act.

It starts with measuring, not guessing. A short, clinician-reviewed assessment shows what fits you.
