Ethinylestradiol is a man-made form of the naturally occurring female hormone called oestrogen. It is prescribed to treat period (menstrual) problems, and also to help ease menopausal symptoms. It is usually prescribed alongside another female hormone called a progestogen.
Ethinylestradiol is used to supplement or replace the body's natural oestrogen. It helps to relieve many of the problems associated with the menopause, such as hot flushes, night sweats and vaginal dryness. It can also help to protect against osteoporosis (thinning of the bones) although other treatments are usually preferred for this.
This leaflet is appropriate if you have been prescribed ethinylestradiol for a menstrual disorder or for hormone replacement therapy (HRT). If you have been prescribed it for any other reason, please ask your doctor for further advice or refer to the manufacturer's printed information leaflet. Ethinylestradiol is also one of the hormones that are used in the contraceptive pill (the pill) - there is more information about this in a separate leaflet called Combined hormonal contraceptives.
It is indicated for
- 1) Post menopausal symptoms due to estrogen deficiency.
- 2) Prevention of osteoporosis in postmenopausal women at high risk of future fractures who are intolerant of, or contraindicated for, other medicinal products approved for the prevention of osteoporosis.
- 3) Palliative treatment of prostatic cancer.
- 4) Hormone replacement therapy for failure of ovarian development e.g. in patients with gonadal dysgenesis where initial estrogen therapy is later followed by combined estrogen/progestogen therapy.
- 5) Disorders of menstruation, given in conjunction with a progestogen.
