The Generic name of this drug
Treatment Summary
Norethisterone, also known as norethindrone, is a synthetic hormone used to imitate the effects of progesterone in the body. It is classified as a second-generation progestin and is used as contraception, hormone replacement therapy, and to treat irregular menstrual cycles and endometriosis. Norethisterone was first produced in 1951 and was first used as an oral contraceptive in 1962.

How Estrostep Fe Affects Patients
Norethisterone is a medication taken by mouth that is used as a form of birth control or to treat other hormone-related issues such as menopause or endometriosis. It is a strong version of the hormone progesterone and works to change the cervix and uterus, and also blocks other hormones involved in ovulation. Taking norethisterone may slightly increase the risk of getting breast cancer, so patients should be aware of this and perform regular self-examinations for any lumps.
How Estrostep Fe works in the body
Norethisterone works by binding to progesterone receptors on target cells. This creates a chain reaction that affects genes in the reproductive tract, breast, pituitary, hypothalamus, and central nervous system. As a contraceptive, norethisterone makes the cervical mucus thicker and more difficult for sperm to pass through. It also changes the endometrium, making it less hospitable for implantation. Norethisterone also works on the hypothalamus and anterior pituitary to prevent the release of FSH and LH which stops follicular development, ovulation, and corpus luteum development. When used
