In short
Perimenopause is treated while your periods are still happening, and that changes the plan in three ways.
- You still need contraception until you have gone 12 months without a period.
- Progesterone is usually given for 12 days a month, so you keep a monthly bleed.
- Mood is treated as its own problem, not as an afterthought.
Most women start on a low dose and go up only if symptoms are not fully settled after three to four weeks.
Treatment Overview
What is different about treating perimenopause rather than menopause?
In perimenopause your ovaries still produce oestrogen, but in an unpredictable pattern. Levels can swing high one month and low the next.
That is why a single blood test rarely settles anything, and why the treatment plan is built around your symptoms and your cycle rather than around a number.
Three practical differences follow from still cycling:
| Contraception | Still needed. Pregnancy is still possible in about 2 to 3 per cent of women aged 45 to 49 who use nothing, and under 1 per cent after 50. |
| Progesterone rhythm | Usually cyclical, 200 mg for the first 12 days of the month, which produces a monthly bleed in 80 to 90 per cent of women. |
| Mood | Treated deliberately. The risk of new depression in these years is around 30 per cent, and around 60 per cent if you have had depression before. |
What are the treatment options?
There are three routes, and the right one depends mostly on whether you also need contraception and how heavy your bleeding is.
- Oestradiol plus cyclical progesterone. Continuous 17-beta oestradiol, usually as a patch or gel, plus micronised progesterone for 12 days a month. This is the usual starting point.
- A low dose combined pill. A pill with 20 micrograms of ethinylestradiol treats symptoms, gives contraception and controls heavy bleeding better than standard hormone therapy, because it switches your own cycle off.
- A hormonal coil plus oestrogen. The levonorgestrel coil covers contraception, heavy bleeding and endometrial protection in one device, and oestrogen is added on top for symptoms.
Why is a patch usually preferred over tablets?
Oestrogen through the skin does not pass through the liver first. That means less effect on clotting factors, and a lower risk of clot and stroke than the same dose taken by mouth.
Tablets are still a reasonable choice for many women. They are avoided if you have high triglycerides, active gallbladder disease, migraine, or a known low risk clotting tendency such as heterozygous factor V Leiden.
What dose is used at the start?
Moderate symptoms usually start at transdermal oestradiol 0.025 mg twice weekly, or oral oestradiol 0.5 mg daily.
More severe symptoms start higher, at 0.05 mg transdermal twice weekly or 1 mg oral daily. Hot flush relief normally appears within the first three to four weeks, and the dose is raised if it has not.
Does treatment help mood in perimenopause?
Yes, and this is one of the few areas where perimenopause differs clearly from later menopause. Oestrogen improves mood symptoms during the transition, but not after menopause.
In one trial of 50 perimenopausal women with depression, 68 per cent went into remission on transdermal oestradiol compared with 20 per cent on placebo. Where mood and flushes are both severe, both hormone therapy and an SSRI are often needed.
Who Is a Good Candidate?
- Your periods have become irregular, closer together or further apart, and symptoms have started
- Flushes, night sweats or broken sleep are affecting your work or your relationships
- Mood changes, irritability or low mood have appeared alongside cycle changes
- Bleeding has become heavy and you also want contraception
- You are under 60 and within 10 years of your last period
- A history of breast cancer, coronary heart disease, stroke or a previous blood clot
- Active liver disease
- Vaginal bleeding that has not been explained, which needs investigation before any hormone is started
- Very heavy bleeding, which needs an endometrial biopsy first
What Happens During the Consultation
-
1
Your cycle, your symptoms, your contraception
When your periods changed and how, which symptoms bother you most, and whether you still need contraception. In perimenopause this history is worth more than any single hormone level.
-
2
Risk assessment and bleeding check
Cardiovascular and breast cancer risk are calculated before hormones are started, because they decide both the route and whether hormones are right at all. Very heavy bleeding is investigated first.
-
3
Choosing the regimen
Patch, gel or tablet, cyclical progesterone or a hormonal coil, or a low dose pill if contraception and heavy bleeding are both in play.
-
4
Review at three to four weeks
Flush relief usually appears in this window. If it has not, the dose goes up rather than the treatment being abandoned.
Program Structure & Follow-Up
How is treatment followed up?
The first review is at three to four weeks, when hot flush relief should be showing. After that, reviews settle into a yearly rhythm unless something changes.
What is checked and when
| 3 to 4 weeks | Symptom relief, side effects, dose adjustment if flushes persist |
| 3 months | Bleeding pattern, mood, tolerance of the progesterone |
| Every 12 months | Dose, route, endometrial protection, breast screening, and whether the balance still favours treatment |
What about bleeding?
On a cyclical regimen, 80 to 90 per cent of women have a monthly withdrawal bleed. That is expected, not a problem.
Bleeding that is heavy, that starts after a long gap, or that persists beyond six months on a continuous regimen needs an endometrial biopsy. Ultrasound alone is not reliable enough to rule out hyperplasia in women on hormone therapy.
When do you switch to a continuous regimen?
Once you are more than two to three years past your last period, progesterone is usually given every day instead of 12 days a month. That produces no bleed in most women, which is why most eventually make the switch.
Benefits, Limits & Safety
How well does it work?
Standard doses of oestrogen clear hot flushes completely in about 80 per cent of women and reduce them in the rest. Across 24 trials in 3329 women, oestrogen cut flushes by about 75 per cent compared with placebo.
What are the honest limits?
Hormone therapy is not a treatment for ageing and it is no longer recommended for preventing heart disease, dementia or osteoporosis. It is used for symptoms, and bone benefit comes along as a bonus.
It also does not fix everything that goes wrong with sleep in these years. Restless legs and sleep apnoea often start in the same decade and need their own treatment.
What about the risks?
For a healthy woman starting in her late 40s or 50s, the absolute numbers are small. Over five years, starting between 50 and 59, combined therapy means roughly three extra breast cancers per 1000 women and three extra pulmonary embolisms, against five fewer deaths from any cause.
Transdermal oestrogen showed no excess clot risk even in women with a clotting mutation or a high BMI, which is the main reason it is the default route.
What side effects are common?
- Breast soreness, usually helped by a lower dose
- Monthly bleeding on a cyclical regimen
- Mood changes or bloating from the progesterone, most often on cyclical regimens
- Irregular spotting in the first months of a continuous regimen
Progesterone is taken at bedtime, because some of its breakdown products cause drowsiness.
What treatment achieves
Complete relief of hot flushes in about 80 per cent of women, a 75 per cent average reduction across trials, and genuine improvement in mood during the transition.
What is watched
Bleeding pattern, breast screening, blood pressure, and a yearly review of whether the dose and route are still right for your age.
When hormones are not used
Previous breast cancer, coronary heart disease, stroke, previous clot, active liver disease, or unexplained vaginal bleeding that has not been investigated.
Cost & Program Investment
Consultation and treatment are quoted individually, because the plan depends on which route you need and whether contraception and bleeding control are part of it. You will be given the full cost of the consultation, the tests and the prescription before anything is started. There are no packages you have to buy into and no minimum commitment.
Frequently Asked Questions
Yes, until you have gone 12 months without a period. Standard hormone therapy is not contraception. If you need both, a low dose pill or a hormonal coil covers it.
Usually not. Hormone levels swing week to week in perimenopause, so a single result can look completely normal on a bad month. The diagnosis rests on your cycle pattern and your symptoms.
On a cyclical regimen, most likely yes. 80 to 90 per cent of women have a monthly withdrawal bleed. It is usually light, and most women switch to a continuous regimen later to stop it.
Often, yes. A pill with 20 micrograms of ethinylestradiol treats symptoms, gives contraception and controls heavy bleeding. It is avoided if you smoke, have high blood pressure, migraine, or a high BMI.
Usually around age 50 or 51. The pill is tapered by one pill a week rather than stopped abruptly, because sudden withdrawal brings flushes back.
The first attempt to reduce the dose is usually made between three and five years. If you started in your late 40s with severe symptoms, that is often pushed out further, and the goal may be a lower dose rather than stopping.
Yes. Options include taking it vaginally, switching to a hormonal coil which delivers it directly to the womb lining with very little reaching the bloodstream, or a different combination. The progesterone is not optional if you still have a uterus, but the form is.
