The short answer
Usually, if it is treated and checked. High blood pressure is not on estrogen labels’ list of reasons not to take it. In a study of 112,240 women, estrogen by mouth carried more hypertension risk than skin or vaginal forms.
What the label says
Estradiol labels list who should not take estrogen: unexplained bleeding, breast cancer, past clots, stroke or heart attack, liver disease and clotting disorders [1]. High blood pressure is not on that list. The oral tablet label says a general effect of estrogen on blood pressure was not seen, and that blood pressure should be monitored at regular intervals [2]. The patient leaflet adds that high blood pressure, like tobacco use, raises your chances of heart disease [1].
How much does estrogen move blood pressure?
| Study | Who | What it found |
|---|---|---|
| Women’s Health Initiative, blood pressure readings | Women in the hormone trials, oral conjugated estrogens | At one year, systolic pressure was 1.04 mmHg higher on estrogen alone and 1.35 mmHg higher with a progestin, against placebo [3] |
| Women’s Health Initiative, new hypertension | 18,015 women without high blood pressure at the start | New hypertension was 18% more likely during treatment, and the difference faded after it stopped [4] |
| Alberta cohort | 112,240 women aged 45 and older on estrogen alone, 2008 to 2019 | Oral estrogen carried more risk than skin estrogen (hazard ratio 1.14) and vaginal estrogen (1.19); conjugated estrogens more than estradiol (1.08) [5] |
Put plainly: estrogen pills nudge blood pressure up a little on average, and skin forms appear to nudge it less. The Alberta authors concluded that non-oral estradiol at the lowest dose for the shortest time had the lowest risk of hypertension [5].
What else your physician weighs
- Your other heart risks. The estrogen leaflet names high blood pressure, high cholesterol, diabetes, being overweight and tobacco use as things that raise the chances of heart disease [1].
- Your age and time since menopause. The Menopause Society describes the balance of benefit and risk as favorable under 60 or within 10 years of menopause, and less favorable later [6].
- The absolute numbers. In the Women’s Health Initiative, estrogen with a progestin meant 8 more strokes per 10,000 women a year, in women whose average age was 63 [7] [8].
- Whether hormones are needed at all. A non-hormonal medicine may suit some women with harder-to-control blood pressure better, and if dryness or pain with sex is the only problem, low-dose vaginal estrogen carried the least hypertension risk of the routes in the Alberta study [5].
Why the route matters for more than blood pressure
Estrogen swallowed as a pill passes through the liver first; estrogen through the skin does not. In 15,710 strokes, standard-dose patches were not linked to stroke while pills were (rate ratio 1.28) [9]. NICE advises considering patches or gels over pills for women at higher risk of clots, including a BMI over 30 [10]. High blood pressure often travels with those other risks, which is why a physician usually starts with estradiol through the skin. The options are on the estradiol page.
- Before you startKnow your recent readings and the medicines you take for blood pressure. The intake asks for both.
- Once you startKeep checking at regular intervals, as the label advises [2]. Home readings are useful to share.
- If readings climbTell your physician; switching the route or the dose is an option, and so is a non-hormonal treatment.
This applies to
- Women whose high blood pressure is treated and stable
- Women with borderline readings who want to keep an eye on them
This does not apply to
- Women whose blood pressure is very high or untreated: get it under care first
- Women who have had a stroke or heart attack: estrogen labels rule it out [1]
Migraine with aura and smoking change the same risk picture: see HRT with migraine with aura and HRT if you smoke. Every option is on the menopause care page.
