Treatment Summary
Norethisterone is a synthetic progestin hormone used to treat menstrual problems, endometriosis, and contraception. It is a second-generation progestin, more potent than naturally-occurring progesterone, and is sold in combination with estrogen forms for hormone replacement therapy. It was first developed in 1951 in Mexico City and was not available for use as an oral contraceptive until 1962.

Effectiveness
How Larin 24 Fe Affects Patients
Norethisterone is a medication that can be taken by mouth to prevent pregnancy or treat other hormone-related conditions. It is a powerful progestin, meaning it acts similarly to the hormone progesterone, but more strongly. Norethisterone affects the pelvic area, cervical area, and endometrial area, as well as the hormones that help eggs mature and be released from the ovaries. Taking norethisterone may slightly increase the risk of developing breast cancer, so patients should be aware of this and do regular breast exams.
How Larin 24 Fe works in the body
Norethisterone works in a few ways to prevent pregnancy. It thickens the mucus in the cervix, making it difficult for sperm to pass through. It also makes the lining of the uterus inhospitable to an embryo, preventing it from implanting and growing. Norethisterone also has a negative feedback effect on the hormones that control ovulation and follicular development, stopping those processes from occurring. When used for hormone replacement therapy, norethisterone helps to protect against overgrowth of the endometrium, which can lead to cancer. Finally, it has a low affinity for other steroid receptors,
