Patient Education

Norethindrone


Norethindrone is used to treat endometriosis, a condition in which the type of tissue that lines the uterus (womb) grows in other areas of the body and causes pain, heavy or irregular menstruation (periods), and other symptoms. Norethindrone is also used to treat abnormal periods or bleeding and to bring on a normal menstrual cycle in women who menstruated normally in the past but have not menstruated for at least 6 months and who are not pregnant or undergoing menopause (change of life). Norethindrone is also used as a test to see if the body is producing certain female hormones (natural substances that affect the uterus). Norethindrone is in a class of medications called progestins. It works by stopping the lining of the uterus from growing and by causing the uterus to produce certain hormones. Norethindrone is also used to prevent pregnancy. Norethindrone is sold under different brand names and is taken in smaller amounts when it used to prevent pregnancy. This monograph does not include information on the use of norethindrone to prevent pregnancy. If you would like more information on that use of norethindrone, read the monograph called ''Progestin-Only Oral Contraceptives.''

Progestin-Only (norethindrone) Oral Contraceptives


Progestin-only (norethindrone) oral contraceptives are used to prevent pregnancy. Progestin is a female hormone. It works by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus. Progestin-only (norethindrone) oral contraceptives are a very effective method of birth control, but they do not prevent the spread of AIDS and other sexually transmitted diseases.
