Tibolone is used to mimic the activity of the naturally occurring female sex hormones oestrogen and progestogen in the body. It helps to restore the natural balance of these hormones.
It is a female sex hormone, sometimes known as a hormone replacement therapy (HRT). Tibolone is broken down in the body to make hormones and it then has an effect similar to combined HRT (a type of HRT containing the female hormones oestrogen and progestogen).
It is used to relieve symptoms that start to occur when the female body no longer produces certain hormones such as oestrogen. This may occur after the menopause, also known as the change of life, or after surgery to remove the ovaries. Tibolone may also be used to stop your bones from becoming brittle.
In general this drug is used to treat symptoms associated with a lack of oestrogen in women who have gone through the menopause (change of life) more than one year ago.
Benefits of being on this drug can include replacement of lost hormones leading to an improvement in a number of symptoms including hot flushes, night sweats, dryness or irritation of the vagina and reduced sex drive. Tibolone can also reduce the likelihood of your bones becomes brittle and breaking by preventing the bone disease osteoporosis.
Listed below are the typical uses of tibolone.
- Prevention of bone fractures in women
- Treatment of symptoms associated with low levels of the hormone oestrogen in women.
On occasion your doctor may prescribe this medicine to treat a condition not on the above list. Such conditions are listed below.
