What tibolone is for
Tibolone is a type of hormone replacement therapy (HRT) that’s used to help with symptoms caused by the menopause, including:
- a hot face, neck and chest (hot flushes)
- vaginal symptoms
- low mood
It's also sometimes prescribed to help prevent weakening of the bones (osteoporosis) after the menopause.
Although some types of HRT can be used while your periods are still changing (perimenopause), tibolone is usually only recommended if it’s been at least 12 months since your periods stopped.
How to take tibolone
Tibolone comes as tablets that you take once a day.
Take 1 tablet a day at the same time each day. Swallow the tablet whole with some water.
The pack containing the tablets will usually be labelled with days of the week and arrows to help you make sure you take your tablets on the right day.
Check the instructions to make sure you take your medicine correctly.
Ask a pharmacist or doctor for advice if you're not sure how to take it or have any problems taking it.
If you miss a dose of tibolone
If you forget to take a dose of tibolone, take it as soon as you remember, unless it’s more than 12 hours since you were supposed to take it.
If it’s more than 12 hours later, skip the missed dose and take the next one at the usual time.
If you take too much tibolone
Taking an extra dose of tibolone is unlikely to cause problems, but it’s important to get medical advice if you take too much as it can sometimes be dangerous.
Urgent advice: Speak to a pharmacist as soon as possible if:
- you’ve taken more than your prescribed dose of tibolone and you have symptoms
If you’re unable to speak to a pharmacist, or you took too much of your medicine on purpose, call NHS 111 for advice.
Find a pharmacyIf you're told to go to A&E, do not drive. Ask someone to drive you or call 999 and ask for an ambulance.
Bring the tibolone packet or leaflet inside it, any remaining medicine, and any other medicines you take.

Tibolone can sometimes cause more serious side effects, although most of them are rare.
Possible serious side effects of tibolone include:
- sudden, severe headaches (similar to migraine headaches)

- weakness on 1 side of the face (the mouth or eye may droop), difficulty raising the arms and keeping them raised, difficulty speaking (speech may be slurred) – these may be symptoms of a stroke
- an allergic reaction (anaphylaxis) – causing symptoms such as a swollen throat or tongue, a raised, itchy rash and difficulty breathing
There’s also an increased risk of getting breast cancer or womb cancer if you take tibolone, particularly if you take it for a long time. Your doctor will discuss the risks and benefits with you.
Immediate action required: Call 999 if:
- you're taking tibolone and think you might be having anaphylaxis, a pulmonary embolism, heart attack or stroke
