Indications for use

Hormonal contraception

Mechanism of action

Demulen 1/50 is a combined estrogen-progestogen drug providing a contraceptive effect. When taking this birth control drug, it suppresses the pituitary secretion of gonadotropic hormones. The contraceptive effect has a direct relation with several mechanisms. The estrogen component is ethinyl estradiol. It contains ethinodiol as a progestogen component. Under the influence of ethinodiol, there is a blockade of release of releasing factors (LH and FSH) of the hypothalamus. It also provides an inhibition of pituitary secretion of gonadotropic hormones, which leads to inhibition of follicular maturation and the release of an egg ready for fertilization (violation of the ovulation process). The contraceptive effect is enhanced by ethinyl estradiol. It increases the viscosity of cervical mucus. Along with the contraceptive effect, when taken regularly, it normalizes the menstrual cycle and helps to prevent the development of a number of gynecological diseases, and acne.

Mode of application and dose

Oral route administration: 1 tablet daily, starting from the 5th day of the menstrual cycle. If there are 21 tablets in the package, after taking the latter a 7 days break is followed. If the package contains 28 tablets, they are taken daily without interruption (7 tablets contain a preparation of ferrum or placebo). If menstruation is delayed, pregnancy should be excluded. When menstruation occurs, the drug is resumed 7 days after taking the last pill of the previous cycle. If, on the background of regular intake, menstruation has not occurred, the course is continued after exclusion of pregnancy.
