Dienogest is used in contraception and mennorhagia (heavy menstrual bleeding)

How it works

Dienogest belongs to a class of drugs called as progestogens. It may be used as a contraceptive alone or in combination with estrogens (in combined oral contraceptive pills). It suppresses ovulation (a process in which a mature egg is released from the ovary) and also thickens secretions from the cervix and vagina inhibiting sperm penetration and alters the lining of the uterus thereby reducing the possibility of the fetus implantation.
