Lynoral is commonly known as ethinyl estradiol. This drug is a synthetic form of estrogen - female sex hormone. This medicine works by thickening the cervical mucus, changing the uterine lining and preventing ovulation.

Lynoral pills


Lynoral is mainly used to prevent pregnancy. It is used to manage the symptoms of menopause such as breast cancer, osteoporosis after menopause, dysfunctional bleeding in uterus, dysmenorrheal and female hypogonadism. This medicine may also be taken with other drugs as a birth control pill or oral contraceptive. It can also be used for the regulation of the menstrual periods.

How To Use

In hypogenitalism (underdevelopment of external genitalia) and primary amenorrhoea (absence of menstruation), 0.05-0.1 mg (0.00005-0.0001 g) is usually prescribed 2 times a day for 3-4 weeks, followed by gestagenic drugs (e.g. progesterone) for 6-8 days. The course of treatment is repeated 5-6 times.

In hypofunction (reduced function) of ovaries and secondary amenorrhoea (cessation of normal menstrual cycles for a period of more than 6 months) prescribe the drug in the same dose 1-2 times a day for 2-3 weeks, then for 6-8 days - gestagenic drugs (progesterone 5-10 mg per day intramuscularly or pregnine 10-30 mg under the tongue 3 times a day).

In menopausal disorders, women under 45 years of age should take 0.01-0.02-0.05 g of ethinylestradiol daily for several days in a row, then progesterone or pregnine for 6-8 days. The course of treatment is repeated 2-3 times.

To eliminate neurovascular disorders in estrogenic insufficiency (insufficient content of female sex hormones), the drug is administered at 0.01-0.02 mg daily for 10-15 days; the course of treatment can be repeated after a break of several days.

In dysmenorrhoea (menstrual cycle disorder) in women with signs of uterine underdevelopment, ethinyl estradiol is administered immediately after the end of menstruation at 0.01 mg per day for 2-3 weeks daily or every other day.

Ethinyl Estradiol

Ethinyl estradiol is a synthetic form of the hormone estrogen, commonly used in combination with progestins as a component of various birth control pills (oral contraceptives). It mimics the action of natural estrogen in the body and helps prevent pregnancy primarily by inhibiting ovulation (the release of an egg from the ovary).

Apart from contraception, ethinyl estradiol is also used in hormone replacement therapy for menopausal symptoms, such as hot flashes and vaginal dryness.
