Femynor is a monophasic low dose birth control means. This birth control drug contains ethinyl estradiol and norgestimate devoted to taking the pregnancy occurrence under control.
Indications for use
Mechanism of action
Femynor intake results in an abrupt reduction in the secretion of gonadoliberin. As a result, the production of FSH is inhibited by the pituitary gland, which, in turn, decelerates the growth and maturation of the follicles in the ovaries. Progestin suppresses the release of LH by the pituitary gland which fosters the ovulation suppression. Moreover, ethinyl estradiol and norgestimate magnify the cervical mucus viscosity, which prevents the penetration of spermatozoa into the uterine cavity. Under the influence of combined oral contraceptive drugs, endometrium changes take place which complicates a fertilized egg implantation.
Mode of application and dosage
Femynor is prescribed as a 28 days-course. The breaks are not necessary. The drug should be taken approximately at the same time washed down with a small amount of water. The correct order is specified on the blister. The next package should be started when the latest placebo pill is taken.
The cases of an overdose are not enormous. The most common signs of this condition are vomiting, nausea, and vaginal bleeding. The specific therapy is not required. The gastric lavage is prescribed as the main way to excrete the hormones from the blood plasma.
