The Generic name of this drug
Treatment Summary
Norethisterone, also known as norethindrone, is a hormone used to treat irregular menstruation and endometriosis. It was first developed in 1951 and released on the market for use as an oral contraceptive in 1962. It is a type of synthetic progestational hormone that is more potent than the natural hormone progesterone, and it is often combined with estrogen derivatives to be used in contraception and hormone replacement therapy.

Effectiveness
How Loestrin 24 Fe Affects Patients
Norethisterone is a pill taken orally that helps regulate hormones and can be used for birth control or to treat other hormone-related issues such as menopause symptoms and endometriosis. It works by altering the cervix and endometrium as well as halting the release of hormones in the pituitary gland, which affects ovulation. Taking norethisterone or other progestin-only pills can slightly increase the risk of breast cancer, so doctors advise patients to check for any developing lumps or masses through regular self-examinations.
How Loestrin 24 Fe works in the body
Norethisterone works in the body to prevent pregnancy by blocking sperm from reaching an egg. It also prevents ovulation and stops the uterus from thickening. For menopausal women, it can be used as a form of hormone replacement therapy to protect against endometrial hyperplasia, which can lead to cancer. Norethisterone has a low affinity for other steroid receptors, such as the androgen receptor and glucocorticoid receptor, but is thought to cause some adverse effects like acne and changes in serum lipids.
