Hormone replacement therapy (HRT) is a treatment used to help menopause symptoms. It replaces the hormones oestrogen and progesterone, which fall to low levels as you approach the menopause.
Menopause symptoms HRT can help to treat include:
- hot flushes
- night sweats
- sleep problems
- mood swings
- anxiety and low mood
- vaginal dryness
Menopause is when your periods stop due to lower hormone levels. It usually affects women between the ages of 45 and 55 but it can happen earlier. It affects anyone who has periods.
Oestrogen and progesterone are an essential part of period cycles, ovulation and pregnancy. They also keep your bones healthy. As you get older, the loss of these hormones can have a big effect on your body.
To replace these hormones, you'll usually take a combination of oestrogen and progestogen. If you've had a hysterectomy to remove your womb you can take oestrogen on its own.
Who can take HRT
You can usually take HRT if you're having menopause symptoms.
But HRT may not be suitable if you:
- have a history of breast cancer, ovarian cancer or womb cancer
- have a history of blood clots – you may need to use patches or gels rather than tablets
- have untreated high blood pressure – your blood pressure will need to be controlled before you can start HRT
- have liver disease
- are pregnant – it's still possible to get pregnant while taking HRT, so it's important to use contraception until 2 years after your last period if you're under 50, or for 1 year after the age of 50
If any of these apply to you, alternatives to HRT may be recommended instead.
Non-urgent advice: See a GP if:
- you're over 45 years old and think you're having menopause symptoms and you're considering starting HRT
- you're under 45 years old and think you're having menopause symptoms – this may be premature menopause or early menopause

Questions to ask your doctor
Before you see a GP, it's a good idea to be prepared so you get exactly what you need from the appointment.
If your periods have changed in recent months, make a note of it so you can tell the GP. Also tell them about any medicines or herbal remedies you're taking.
Your questions could include:
- how will HRT help me?
- how soon will I feel better?
- what are the benefits and what are the risks?
- is HRT the only treatment I can have for my symptoms?
- how long will I have to take it for?
- how will I know what type will work best for me?
A GP should be able to answer your questions and help you choose the type of HRT that's suitable for you.
After you start taking HRT
You'll usually start with a low dose, which may be increased later. Your symptoms should improve after a few days or weeks.
A GP will usually recommend a review appointment 3 months after you start taking HRT, or if you change your type of HRT. This is to see how well it's working. If everything is OK, you'll usually have 1 review a year.
If your symptoms do not improve or you get side effects, a GP may suggest either:
- changing your dose
- changing the type of HRT you're taking
- referring you to a menopause specialist doctor.
You'll usually need to take HRT for 2 to 5 years, but it can be longer in some cases.
