What Is Nora-BE Used For?

Advantages and Disadvantages of Using Nora-BE

Progestin-only birth control pills (such as Nora-BE) have several advantages and disadvantages. They are the preferred type of birth control pill for breastfeeding women, since they usually do not interfere with the quantity and quality of breast milk (see Nor-QD and Breastfeeding). Also, they may be preferred for women who are at high risk for blood clots or other problems that can be caused or worsened by estrogen, such as:
  • Smokers
  • Women over 35 years old
  • Women with a history of blood clots, heart disease, and other problems.
The primary disadvantage of Nora-BE and other progestin-only pills is that they are less effective than combined oral contraceptives. Other downsides include irregular (and often unpredictable) periods, compared to combined oral contraceptives (which cause regular, predictable periods). Also, compared to combined oral contraceptives, there is less room for error (missing pills or taking them late) with progestin-only pills. For instance, taking Nora-BE just a few hours late can increase the risk of pregnancy. Another disadvantage is that Nora-BE and other progestin-only pills may increase the risk of ectopic pregnancy (pregnancy outside the uterus, sometimes called a "tubal pregnancy").

How Does Nora-BE Work?

Because Nora-BE contains only a progestin, it is slightly less effective than pills that contain both an estrogen and a progestin. Nora-BE and other progestin-only oral contraceptives stop ovulation in only about half of the women who take them.
Because the drug is not very effective at preventing ovulation, it also relies on other mechanisms to prevent pregnancy. Nora-BE alters the lining of the uterus (the endometrium), making it less receptive to an embryo. It also changes the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus.
Unlike combined oral contraceptives, there are no inactive or "placebo" pills in each pack of Nora-BE. Every tablet contains the active hormone, and there is no break in between pills or packs. Because there are no breaks, menstrual periods often occur at irregular intervals.
