PREGNANCY AND BREASTFEEDING SAFETY:

  • Oral contraceptives are generally avoided during pregnancy. Use of norethindrone during pregnancy has been associated with masculinization of female infants.
  • Small amounts of progestin pass into breast milk and are detectable in the infant. Use of birth control pills during lactation has been associated with decreased milk production. Norethindrone may be used by breastfeeding women.

STORAGE:

  • Norethindrone tablets should be stored at room temperature, 15 C to 30 C (59 F to 86 F).

DOSING:

  • The recommended dose is one tablet daily at the same time of the day.

DRUG CLASS AND MECHANISM:

  • Norethindrone is a progestin that is used as an oral contraceptive. Progestins prevent pregnancy by inhibiting ovulation (release of the egg), making it more difficult for sperm to penetrate the uterine mucus that surrounds the egg, and therefore, for fertilization to take place. Progestins also change the uterine lining to prevent the fertilized egg from implanting in the uterus.
  • The FDA approved norethindrone in January, 1973.
