Treatment Summary
Norethisterone (also known as norethindrone) is a type of synthetic hormone used to treat irregular periods, endometriosis and as part of combination contraception and hormone replacement therapy. It is a more potent form of progesterone, a hormone produced naturally in the body. Norethisterone was first developed in 1951 and approved for contraception in 1962.

Effectiveness
How Cyclafem 1/35 Affects Patients
Norethisterone is a hormone pill used for contraception, menopausal symptoms, and endometriosis. It is very similar to the hormone progesterone, but has a much stronger effect on the body. It affects the pelvic area, as well as hormones involved in ovulation. Taking norethisterone or other combined oral contraceptives may slightly increase the risk of breast cancer, so it's important for patients to be aware of this risk and to regularly check for any lumps or changes in their breasts.
How Cyclafem 1/35 works in the body
Norethisterone works by influencing the cells in the reproductive system. It thickens the cervical mucus to block sperm, and changes the endometrium to make it difficult for a fertilized egg to attach. It also acts on the hypothalamus and pituitary glands to reduce production of hormones that cause ovulation. When used as part of hormone replacement therapy, norethisterone prevents endometrial hyperplasia and lowers the risk of endometrial cancer. It has low activity on other steroid receptors, but may cause side effects like acne and changes in serum lipids.
