Why isn’t my HRT working? Understanding your symptoms and what to do next

You started hormone replacement therapy (HRT) hoping to sleep better, have fewer hot flushes and get back to feeling like yourself. But perhaps you’re still waking at night, feeling exhausted or wondering why you haven’t noticed the improvement you hoped for.

Or maybe HRT helped at first, and now some symptoms have returned.

It can feel disappointing, particularly when other women describe their treatment as life-changing. You may wonder whether you’re using it correctly, whether you need a higher dose, or whether HRT simply isn’t for you.

If you’re still struggling, you deserve a review that looks carefully at what is happening.

There are several reasons HRT may not be helping as much as expected. Understanding them can help you have a more useful conversation with your prescriber.

What does “HRT isn’t working” mean for you?

Before changing treatment, it helps to be specific. Have your hot flushes improved but your sleep hasn’t? Are you feeling better overall but still experiencing vaginal dryness? Or have you developed headaches or low mood since starting treatment?

These are different situations and may need different approaches.

HRT is the most effective treatment for hot flushes and night sweats, but it cannot be expected to resolve every symptom experienced around menopause. [1] A partial improvement is worth recognising, while still taking the symptoms that remain seriously.

1. Your treatment may need more time

Some women notice an improvement within days or weeks. However, HRT can take up to three months to work fully. [2]

This can be difficult when symptoms have already affected your life for months. A short symptom diary can help you notice gradual changes that might otherwise be easy to miss.

A review is usually recommended around three months after starting or changing HRT, and annually once treatment is settled. [2] Contact your clinician sooner if symptoms are difficult to manage, side effects are troublesome or something concerns you.

Giving treatment time should come with support and a plan for reviewing it.

2. The dose, formulation or treatment schedule may need adjusting

There isn’t one HRT prescription that suits everyone. Tablets, patches, gels and sprays offer different ways of taking oestrogen, and the choice should reflect your medical history, preferences and response.

Your clinician may suggest adjusting the dose or changing the preparation. [2] The schedule also matters: some women take progestogen for part of each month, while others take it every day. Whether you are still having periods helps guide this choice. [3]

It is useful to explain exactly what remains troublesome and what has improved. That helps your prescriber judge whether an adjustment is likely to help.

Persistent symptoms do not automatically mean your oestrogen dose is too low.

Increasing oestrogen can also increase side effects. If you have a womb, your progestogen prescription may need reviewing alongside any increase to ensure the womb lining remains adequately protected. [4]

3. Application, consistency and absorption can make a difference

Busy days, confusing instructions, supply problems or patches that won’t stay attached can make treatment harder to use consistently.

If you use a patch, gel or spray, check:

• Are you using the prescribed amount and changing patches on the correct days?
• Does your patch stay fully attached?
• Are you applying the product to the areas recommended in its leaflet?
• Are you allowing the recommended drying time and waiting before washing the area?

Instructions differ between products, so follow the leaflet for your particular preparation. Your pharmacist can help check your technique. [5]

Even when treatment is used correctly, absorption through the skin varies between people. A preparation that works well for one woman may be less suitable for another. Changing the formulation may sometimes help. [6]

If you have missed doses, mention this openly. It helps us understand your response and find a routine that works for you.

4. Your natural hormones may still be fluctuating

During perimenopause, your own hormone levels can rise and fall unpredictably. HRT may help your symptoms without removing all these fluctuations. [6]

You may therefore have better and worse days, or notice symptoms at particular points in your cycle.

Record when symptoms occur, any bleeding, and when you take each component of HRT. If you take progestogen for part of the month, note whether the difficult days coincide with it.

A pattern is often more useful than a description of one particularly bad day.

5. Side effects may feel like continuing menopause symptoms

Some HRT side effects overlap with the symptoms you hoped to treat. Headaches, nausea, breast tenderness and mood changes can occur with oestrogen or progestogen. Progestogen may also cause tiredness or dizziness. [7]

Many side effects improve with time, but persistent or troublesome symptoms should be discussed.

If you feel worse during the days you take progesterone or another progestogen, tell your clinician. A different preparation or, for some women, a suitable hormonal coil may be considered. [8]

Progestogen is usually essential alongside systemic oestrogen if you have a womb: it protects the womb lining from becoming excessively thickened. Do not stop it or reduce it yourself. [4]

The aim is to find a combination you tolerate while maintaining that protection.

6. Vaginal and urinary symptoms may need additional treatment

Your hot flushes may improve while vaginal dryness, soreness, discomfort during sex or some urinary symptoms continue.

These symptoms may need vaginal oestrogen alongside systemic HRT. It acts mainly in the local tissues, with minimal absorption into the bloodstream. Vaginal moisturisers and lubricants may also help. [3]

However, symptoms such as itching, discharge, pain or burning when passing urine can have other causes. They should be assessed rather than automatically attributed to menopause.

Please mention intimate symptoms at your review, even if they feel awkward to discuss. They
can affect comfort, relationships and everyday life, and deserve attention.

7. Other medicines or supplements may affect treatment

Tell your prescriber about everything you take, including medicines from other services, over-the-counter products and herbal remedies.

Some medicines can affect HRT, particularly oral preparations. St John’s wort, for example, can make some HRT tablets and capsules less effective. [9]

Mention any new medicine started around the time your symptoms changed. A medicines
review can help identify interactions or side effects that might be contributing.

“Natural” products can still interact with prescribed treatment, so check before adding a supplement.

8. There may be more than one reason you feel unwell

Menopause may be part of the picture without explaining every symptom.

Persistent tiredness can also relate to poor sleep, stress, iron-deficiency anaemia, thyroid problems or sleep apnoea. Depending on your symptoms, your clinician may recommend blood tests or further assessment. [10]

For example, feeling exhausted alongside heavy bleeding may prompt assessment for anaemia. Loud snoring, gasping during sleep or marked daytime sleepiness may need investigation for sleep apnoea.

HRT may help some menopause-related mood symptoms, but depression or significant anxiety may also need their own assessment and treatment. [3]

Looking at other possible causes helps us give your symptoms the attention they need.

What if HRT helped at first but now seems less effective?

Symptoms returning do not prove that your body has become “used to” HRT or that you need a higher dose.

A review can revisit the questions above: has the product or routine changed? Are patches staying attached? Have you started another medicine? Are symptoms following a cycle? Have sleep, stress or your general health changed?

These questions help establish what to assess next. Avoid repeatedly increasing your dose without a review.

Would a hormone blood test help?

For most women going through menopause at the usual age, hormone blood tests are not routinely needed to monitor HRT. Treatment decisions are usually guided by symptoms, response, side effects and medical history. [11]

A single oestrogen result is a snapshot. Levels vary, and in perimenopause the test cannot distinguish your own oestrogen from the oestrogen supplied by HRT. There is no single target level that reliably predicts symptom relief for everyone. [6]

Testing may be useful in selected circumstances, such as suspected poor absorption. Younger women with premature ovarian insufficiency may need a different assessment. Your clinician should explain what question a test would answer.

Blood tests for other possible causes of symptoms are a separate consideration.

Could testosterone be the missing piece?

Testosterone may be considered for persistent, distressing low sexual desire when conventional HRT has not helped enough, after assessing other contributing factors.

These can include pain during sex, medicines, mood and relationship difficulties. A low testosterone result alone does not establish a need for treatment.

Current evidence does not support routinely prescribing testosterone for tiredness, brain fog, low mood or general wellbeing. If it is appropriate, treatment requires discussion of off-label use, benefits, risks and monitoring. [12]

Support beyond the prescription

Sleep, nutrition, movement, emotional wellbeing and practical support also deserve attention. Your review should allow space for how symptoms affect work, relationships and daily life.

Menopause-specific cognitive behavioural therapy (CBT) can be considered alongside HRT for hot flushes and night sweats, and for associated sleep problems. [3]

Supporting these areas can form part of an individual treatment plan. It should feel manageable and relevant to your circumstances.

How to prepare for your HRT review

Bring or write down:

• The names, strengths and doses of every part of your HRT.
• When you started treatment and when anything last changed.
• What has improved and the symptoms that still affect you most.
• Any side effects, bleeding or missed doses.
• Other medicines and supplements you take.
• A brief symptom diary, if you have one.

Be clear about what you most want help with, whether that is sleeping through the night, managing symptoms at work or feeling comfortable during sex.

When to seek advice about bleeding

Unscheduled bleeding can occur when starting or changing HRT, but it should be reported and reviewed.

Seek prompt advice if bleeding is heavy or prolonged, begins more than six months after starting HRT or more than three months after a treatment change, or returns after a settled period without bleeding. Your clinician will consider the pattern, your prescription and individual risk factors to decide whether investigations are needed. [13]

Finding a treatment plan that works for you

You do not need to compare your progress with someone else’s experience. What matters is
how you feel, what is improving and what still needs attention.

At Your Menopause Care with Rupa, I offer personalised reviews for women already using
HRT, as well as those considering treatment for the first time. We can review your symptoms,
current treatment, medical history and wider wellbeing, and discuss appropriate next steps.
You deserve time to ask questions and understand your options.
