Nordette belongs to a group of
birth control pills known as combined
oral contraceptives, the most common type of birth control pill. It is called a combined oral contraceptive because it contains a combination of two different types of hormones. Nordette contains both an estrogen (ethinyl estradiol) and a progestin (levonorgestrel).
The hormones in Nordette mainly prevent pregnancy by preventing ovulation (the maturation and release of eggs from the ovaries). Nordette also works in two other, less important ways. It 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. Nordette also alters the lining of the uterus (called the endometrium), making it less receptive to an embryo.
