What is Menopausal Hormone Therapy (MHT) and is it Safe? | Fact Sheet | Australasian Menopause Society Hub

Menopausal hormone therapy (MHT) is a type of hormone medicine used to treat the symptoms of perimenopause and menopause. This medicine used to be called hormone replacement therapy (HRT).
Symptoms of perimenopause and menopause mainly happen because the hormone oestrogen (Opens in new tab) starts to decrease. Symptoms can be different for each person. Some people may have more symptoms or stronger symptoms than others.
Symptoms can affect people’s lives in different ways.
Some of the common symptoms include:
Some people experience hot flushes for a few years. However, most people find these hot flushes stop within 10 years. A small percentage of people continue having hot flushes for longer than 10 years. Some symptoms like vaginal dryness don’t stop but continue to get worse as you age.
Some people have symptoms that make it hard to carry out daily duties at home and work. Taking MHT may be able to help with reducing the symptoms that impact your everyday life. MHT lessens symptoms by adjusting the levels of oestrogen and progesterone hormones in your body.
There are benefits and risks to MHT, so it’s important to talk with your doctor before you start or stop using it. There are also non-hormonal alternatives to MHT.
If you have symptoms of perimenopause or menopause prematurely (younger than 40 years of age), it is important to speak with your doctor. If your symptoms are confirmed because of premature menopause, you may be at greater risk of developing heart disease or osteoporosis. Taking MHT until you turn 50 can help reduce these risks.
There are a few types of MHT, including:
Combined oestrogen and progestogen MHT is suitable if you have a uterus. Taking oestrogen alone can increase the risk of cancer of the lining of your uterus (endometrial cancer), so you should also take progestogen to protect against this.
Oestrogen-only MHT is suitable if you have had a hysterectomy (removal of your uterus) or if you have a hormonal intrauterine device (IUD) in place. The IUD contains progesterone, which helps protect against endometrial cancer.
Tibolone is suitable if you had your last period at least 12 months ago. It is a synthetic steroid and an alternative to oestrogen and progestogen medicines. Tibolone can help relieve hot flushes and prevent bone loss. It can also help improve sexual function and libido. Tibolone is not suitable for people who have had breast cancer.
Oestrogen plus SERM is suitable if you have a uterus. It contains a combination of oestrogen with a SERM (selective oestrogen receptor modulator) called bazedoxifene. It can help relieve menopausal symptoms of hot flushes and night sweats and help to prevent osteoporosis. Oestrogen plus SERM is another option if you experience side effects from progestogen.
Vaginal oestrogen cream or pessaries can be prescribed if you have vaginal dryness, irritation and discomfort during sex, or urinary symptoms (such as urgency or recurring urinary tract infections). Depending on your symptoms and medical history, local vaginal oestrogen may be used on its own or with MHT.
Testosterone therapy is not an MHT, but your doctor can prescribe it if you are concerned about a low libido (reduced interest in sex).
MHT is an effective treatment for hot flushes and vaginal dryness. It can also improve the following symptoms associated with low oestrogen levels:
MHT helps to protect your bones by slowing bone loss, which can happen during menopause and as you get older. It can also help rebuild bone density.
Some doctors will recommend that you start MHT to protect against osteoporosis, even if you do not have any symptoms of perimenopause or menopause.
Taking MHT can lower the chance of heart disease for some people. Talk with your doctor to understand your risk of heart disease.
Some people may also notice improvements in concentration, brain fog, joint discomfort and overall wellbeing. Research into the broader health effects of MHT is ongoing.
Current international recommendations say that the benefits of MHT outweigh the risks when used to treat significant menopause symptoms. MHT is effective and safe for most healthy females.
Side effects of MHT may include:
These side effects often go away within a few months of starting MHT.
Some studies show long term use (more than 7 years) of certain types of MHT can lead to a slightly increased risk of developing breast cancer and blood clots or stroke.
Because these risks are based on specific health factors, it's best to speak with your doctor about the possible benefits and risks before you decide to start or stop taking MHT.
These factors include:
You may not be able to use MHT if you have or had:
If you can't take MHT, your doctor may suggest other non-medical options and treatments that may be helpful.
You can lower your risks associated with MHT by:
Exercising, eating well, not smoking and avoiding too much alcohol and caffeine can also help you stay healthy.
If you have menopausal symptoms that affect your quality of life and want to know what treatments could help, talk to your doctor. They will be able to give you advice based on your personal medical history and symptoms.
If you feel your concerns have not been understood, you can discuss them again with your healthcare professional or seek a second opinion.
If you are taking MHT and your symptoms are not getting better or you're experiencing side effects, speak to your doctor.
See your doctor straight away if you notice signs of a blood clot, such as:
If you take MHT, you should see your doctor 6 months after starting it. MHT should be reviewed at least once a year. You can take MHT at low doses for as long as you need to manage menopausal symptoms but this will depend on your individual risks and symptoms. Most women have symptoms for about 4 to 7 years after menopause.
There are alternatives to MHT medicines. Some prescription medicines that are used to treat other health conditions can also improve symptoms of menopause. They include some:
Non-hormonal MHT medicines for hot flushes are also available and might be suitable for some people. Speak with your doctor about which medicine is likely to be best for your situation.
Another alternative is cognitive behaviour therapy. This is a type of talk therapy that may help you develop coping strategies.
Some natural therapies and over-the-counter treatments available at the pharmacy may help some people. However, not all of these treatments have good evidence to show they work.
