Fematab tablets contain the active ingredient estradiol valerate, which is a naturally occuring form of the main female sex hormone, oestrogen.
What is it used for?
- Hormone replacement therapy to relieve symptoms of the menopause
- Second-line option for preventing osteoporosis in postmenopausal women who are at high risk of fractures and cannot take other medicines licensed for preventing osteoporosis (FemTab 2mg tablets only).
How does it work?
- FemaTab tablets contain the active ingredient estradiol valerate (previously spelt oestradiol valerate in the UK), which is a naturally occuring form of the main female sex hormone, oestrogen.
- Womens' ovaries gradually produce less and less oestrogen in the period up to the menopause, and oestrogen blood levels decline as a result.
