Documented Uses

• Use (kg; approx.) in Germany (2009): >25
• Consumption (g per capita; approx.) in Germany (2009): 0.000305
• For the relief of post-menopausal symptoms and for the prevention of osteoporosis.
• Tibolone is a synthetic estrogen used for treatment of symptoms of menopause and prevention of osteoporosis. Tibolone has been associated with rare instances of acute, clinically apparent liver injury.
• Avoid St. John's Wort. St. John's Wort induces CYP3A4, increasing the metabolism of estrogens and progesterone and therefore reducing the efficacy of tibolone.
• Compounds which inhibit or antagonize the biosynthesis or actions of androgens.
