Signs of severe androgenization in women, such as very severe hirsutism, androgen-dependent severe hair loss leading to baldness (severe androgenic alopecia), often accompanied by severe acne and/or seborrhea. For women of childbearing age, treatment should start on the first day of the menstrual cycle (i.e. the first day of bleeding), and only women with amenorrhea can start medication immediately. In this case, the first day of treatment is considered the first day of the cycle and is routinely observed according to the following recommended usages. On days 1-10 of the cycle, 2 tablets of this drug are swallowed with water every day after meals, in addition to preparations containing estrogen and progesterone, such as 1 oral contraceptive pill per day from days 1-21 of the menstrual cycle, to provide the necessary contraceptive protection and stabilize the menstrual cycle. Women receiving periodic combination therapy should take medication at a fixed time each day. If it is longer than 12 hours, the contraceptive effect of this cycle may be reduced, but this drug and oral contraceptives should still be taken according to the instructions to avoid early bleeding in this cycle. Missed tablets can be ignored, but non-hormonal contraceptive methods should be used for the rest of the cycle (except safe period and temperature measurement). There is an observation period of 7 days after 21 days of medication cessation, during which withdrawal bleeding will occur, and the next cycle of combination therapy will be started exactly 4 weeks after the start of the first course, that is, on the same day of the week, regardless of whether bleeding has stopped. If bleeding does not occur during discontinuation, the necessary diagnostic tests should be performed. After clinical symptoms improve, the daily dose of this drug can be reduced to 1 or half tablet during the first 10 days of combination therapy, which may be sufficient for oral contraceptives alone. Postmenopausal or hysterectomy patients can use this drug alone. Depending on the severity of symptoms, the average dose of the drug should be 1 to half a tablet once a day for 21 days, followed by 7 days of discontinuation.
