This medicine is a Hormone Replacement Therapy (HRT). It contains tibolone, a substance that has favourable effects on different tissues in the body, such as brain, vagina and bone.
This medicine is used in postmenopausal women with at least 12 months since their last natural period.
This medicine is used for:
Relief of symptoms occuring after menopause
During the menopause, the amount of the oestrogen produced by a woman’s body drops. This can cause symptoms such as hot face, neck and chest ("hot flushes"). Tibolone alleviates these symptoms after menopause. You will only be prescribed Tibolone if your symptoms seriously hinder your daily life.
Prevention of osteoporosis
After the menopause some women may develop fragile bones (osteoporosis). You should discuss all available options with your doctor.
If you are at an increased risk of fractures due to osteoporosis and other medicines are not suitable for you, you can use Tibolone to prevent osteoporosis after menopause.
There are three different kinds of HRT:
Tibolone is different from other HRT. Instead of actual hormones (such as oestrogen and progestogen) it contains tibolone. Your body breaks down tibolone to make hormones.
Its effects and benefits are similar to combined HRT.
The use of HRT carries risks which need to be considered when deciding whether to start taking it, or whether to carry on taking it.
The experience in treating women with a premature menopause (due to ovarian failure or surgery) is limited. If you have a premature menopause the risks of using HRT may be different. Please talk to your doctor.
Before you start (or restart) HRT, your doctor will ask about your own and your family’s medical history. Your doctor may decide to perform a physical examination. This may include an examination of your breasts and/or an internal examination, if necessary.
Tell your doctor if you have any medical problems or illnesses.
Once you have started on Tibolone you should see your doctor for regular check-ups (at least once a year). At these check-ups, discuss with your doctor the benefits and risks of continuing with Tibolone.
Go for regular breast screening, as recommended by your doctor.
Be sure to:
If you are not sure about any of the points above, talk to your doctor before taking Tibolone.
If any of the above conditions appears for the first time while taking Tibolone, stop taking it at once and consult your doctor immediately.
Talk to your doctor or pharmacist or nurse before taking tibolone.
As well as benefits, HRT has some risks which you need to consider when you are deciding whether to take it, or whether to carry on taking it.
Tell your doctor if you have ever had any of the following problems, before you start the treatment, as these may return or become worse during treatment with Tibolone. If so, you should see your doctor more often for check-ups:
If you notice any of the following when taking HRT:
For more information, see ‘Blood clots in a vein (thrombosis)’.
Note: Tibolone is not a contraceptive. If it is less than 12 months since your last menstrual period or you are under 50 years old, you may still need to use additional contraception to prevent pregnancy. Speak to your doctor for advice.
Excessive thickening of the lining of the womb (endometrial hyperplasia) and cancer of the lining of the womb (endometrial cancer)
There have been reports of an increased cell growth or cancer of the lining of the womb in women using tibolone. The risk of cancer of the lining of the womb increases the longer you take the medicine.
You may have irregular bleeding or drops of blood (spotting) during the first 3-6 months of taking Tibolone. However, if the irregular bleeding:
Evidence shows that taking tibolone increases the risk of breast cancer. The extra risk depends on how long you use tibolone. In studies with HRT, after stopping HRT the extra risk decreased with time, but the risk may persist for 10 years or more when women have used HRT for more than 5 years. No data for persistence of risk after stopping are available for tibolone, but a similar pattern cannot be ruled out
Looking at women aged 50 to 79 who are not taking HRT, on average, 9 to 17 in 1000 will be diagnosed with breast cancer over a 5-year period. For women aged 50 to 79 who are taking oestrogen-progestogen HRT over 5 years, there will be 13 to 23 cases in 1000 users (i.e. an extra 4 to 6 cases).
Women taking tibolone have a lower risk than women using combined oestrogen-progestogen HRT and a comparable risk with oestrogen-only HRT.
Regularly check your breasts. See your doctor if you notice any changes such as:
Additionally, you are advised to join mammography screening programs when offered to you. For mammogram screening, it is important that you inform the nurse/healthcare professional who is actually taking the x-ray that you use HRT, as this medication may increase the density of your breasts which may affect the outcome of the mammogram. Where the density of the breast is increased, mammography may not detect all lumps.
Ovarian cancer is rare - much rarer than breast cancer. The use of oestrogen-only or combined oestrogen-progestagen HRT has been associated with a slightly increased risk of ovarian cancer.
The risk of ovarian cancer varies with age. For example, in women aged 50 to 54 who are not taking HRT, about 2 women in 2000 will be diagnosed with ovarian cancer over a 5-year period. For women who have been taking HRT for 5 years, there will be about 3 cases per 2000 users (i.e. about 1 extra case).
With use of Tibolone, the increased risk of ovarian cancer is similar to other types of HRT.
Blood clots in a vein (thrombosis)
The risk of blood clots in the veins is about 1.3 to 3 - times higher in HRT users than in non-users, especially during the first year of taking it.
Blood clots can be serious, and if one travels to the lungs, it can cause chest pain, breathlessness, fainting or even death.
You are more likely to get a blood clot in your veins as you get older and if any of the following applies to you. Inform your doctor if any of these situations applies to you:
For signs of a blood clot, see “Stop taking Tibolone and see a doctor immediately”.
Looking at women in their 50s who are not taking HRT, on average, over a 5-year period, 4 to 7 in 1000 would be expected to get a blood clot in a vein.
For women in their 50s who have been taking oestrogen-progestogen HRT for over 5 years, there will be 9 to 12 cases in 1000 users (i.e.an extra 5 cases). With use of tibolone, the increased risk of getting a blood clot in a vein is lower than with other types of HRT.
Heart disease (heart attack)
There is no evidence that HRT or tibolone will prevent a heart attack.
Women over the age of 60 years who use oestrogen-progestogen HRT are slightly more likely to develop heart disease than those not taking any HRT. As the risk of heart disease strongly depends on age, the number of extra cases of heart disease due to use of oestrogen-progestogen HRT is very low in healthy women close to menopause but will rise with more advanced age.
There is no evidence to suggest that the risk of myocardial infarction with tibolone is different to the risk of other HRT.
The risk of getting stroke is about 1.5 times higher in HRT and tibolone users than in non-users. The number of extra cases of stroke due to use of HRT will increase with age.
Other things that can increase the risk of stroke include:
If you are worried about any of these things, talk to your doctor to see if you should take HRT.
Looking at women in their 50s who are not taking HRT, on average, 3 in 1000 would be expected to have a stroke over a 5-year period. For women in their 50s who are taking HRT, there will be 7 cases in 1000 users, over 5 years (i.e. an extra 4 cases).
Looking at women in their 60s who are not taking tibolone – on average, over a 5-year period, 11 in 1000 would be expected to have a stroke. For women in their 60s who are taking tibolone, the figure would be 24 in 1000 (i.e. an extra 13 cases).
HRT will not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start using HRT after the age of 65. Speak to your doctor for advice.
Tibolone is not intended for contraceptive use.
Some medicines may interfere with the effect of Tibolone. This might lead to irregular bleeding. This applies to the following medicines:
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines including medicines obtained without a prescription, herbal medicines or other natural products.
If you need a blood test, tell your doctor or the laboratory staff that you are taking Tibolone, because this medicine can affect the results of some tests.
If you are going to have an operation, make sure your doctor knows about it. You may need to stop taking HRT about 4 to 6 weeks before the operation, to reduce the risk of a blood clot. Your doctor will tell you when you can start taking HRT again.
You can eat or drink normally while you are taking Tibolone.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Tibolone is for use in postmenopausal women only. If you become pregnant, stop taking Tibolone and contact your doctor.
Tibolone is not known to have any effects on alertness and concentration.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose is one tablet every day.
Tibolone should be swallowed without chewing with some water.
Take your tablet at the same time every day.
The strips of tablets are marked with the days of the week. Start by taking a tablet marked with the current day.
For example, if it is Monday, take a tablet marked “Mo” on the top row of the strip. Follow the arrows until the strip is empty. Start the next strip the next day. Do not leave a break between strips or packs.
Your doctor will aim to prescribe the lowest dose to treat your symptom for as short as necessary. Speak to your doctor if you think this dose is too strong or not strong enough.
You should not take tibolone until at least 12 months after your last natural menstrual bleed (period).
If you have had your womb and ovaries removed or are being treated with drugs known as gonadotrophin releasing hormone (GnRH) analogues, for conditions such as endometriosis, you can start taking tibolone immediately.
If you have never used HRT before, you can start taking tibolone straight away.
There are several different types of HRT, such as tablets, patches and gels. Most contain either oestrogen or an oestrogen and a progestogen. With some you have a period, and with some you do not (period-free HRT).
If you are changing over from another type of HRT where you have a period, start taking Tibolone as soon as your period ends.
If you are changing over from a period-free HRT you can start taking tibolone straight away. You can also start straight away if you are being treated for endometriosis.
Tibolone should not be taken by children.
It is unlikely that taking more than one tablet will do you any harm, but you may feel sick, be sick or have some vaginal bleeding.
If you forget to take a tablet, take it as soon as you remember, unless you are more than 12 hours late. If you are more than 12 hours late, just skip the missed tablet and take your next tablet at the usual time.
Do not take a double dose.
If you are going to have surgery, tell the surgeon that you are taking Tibolone. You may need to stop taking Tibolone about 4 to 6 weeks before the operation to reduce the risk of a blood clot (see section 2, Blood clots in a vein). Ask your doctor when you can start taking Tibolone again.
Do not stop taking tibolone because you feel better without first talking to your doctor. It is important to take the medicine for as long as the doctor has told you to. Otherwise the problem might come back.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Most side effects are mild.
The following diseases are reported more often in women using HRT compared to women not using HRT:
For more information about these side effects, see Section 2.
If you think you may have signs of a serious side effect, see a doctor straight away.
You may need to stop taking Tibolone:
Common (affect up to 1 in 10 women):

Uncommon (affects up to 1 in 100 women):
Rare (affects up to 1 in 1000 women):
Some women taking Tibolone have also reported:
There have been reports of breast cancer and of an increased cell growth or cancer of the lining of the womb in women using Tibolone.
