Nora-BE: What Should I Tell My Healthcare Provider?

- Migraines or other unusual or severe headaches
- Cancer (or if you have had cancer in the past)
- Unexplained vaginal bleeding.
Also, let your healthcare provider know if you are:
Make sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Because Nora-BE contains only a progestin, it is not as effective as pills that contain both a progestin and an estrogen (known as combined oral contraceptives
). Nora-BE and other progestin-only oral contraceptives stop ovulation in only about half of the women who take them.
Because Nora-BE is only 50 percent effective at preventing ovulation, it must rely on other mechanisms to prevent pregnancy. The drug 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.
