Tibolone is a type of hormone replacement therapy (HRT) that contains a synthetic (artificial) hormone. Your body breaks down tibolone to make substances that work in a similar way to the hormones oestrogen, progesterone and testosterone.
Tibolone helps to improve menopause symptoms, such as hot flushes, low mood and vaginal dryness or irritation.
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.
Your hormone levels also fall if you have surgery to remove your ovaries, or if you take medicines called gonadorelin analogues, such as leuprorelin for endometriosis.
Tibolone helps restore your hormone levels.
It can also be prescribed to help stop your bones getting thinner after the menopause (osteoporosis).
Tibolone works in a similar way to taking combined HRT containing oestrogen and progestogen. Some studies have suggested it may not be as effective as combined HRT as it may not increase your oestrogen levels as much.
It's only suitable if you had your last period more than a year ago (post-menopause). However, if you've had surgery to remove your ovaries or you're taking gonadorelin analogues you can start taking it straight away.
Tibolone is only available on prescription. It comes as tablets.
Key facts
