What Is Brevicon?
(norethindrone/ethinyl estradiol) is a prescription oral contraceptive
. It is approved for preventing pregnancy and is one of the many versions of "the pill." Brevicon is a monophasic pill, which means that there is only one strength of hormones in each pack (compared with biphasic or triphasic pills, which have different phases of pills that contain different strengths of hormones in each pack).
Who Makes It?
Brevicon is made by Watson Pharmaceuticals. Generic versions of Brevicon are made by various manufacturers (see Generic Brevicon for more information)
How Does Brevicon Work?
Primarily, the hormones in Brevicon prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries). However, it also works to prevent pregnancy in two other, minor ways. Brevicon 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. Lastly, it alters the lining of the uterus (called the endometrium), making it less receptive to an embryo.
Brevicon is a classified as a "combined" oral contraceptive, which means that it contains two different types of hormones. It contains both an estrogen (ethinyl estradiol) and a progestin (norethindrone). Combined oral contraceptives are the most common type of birth control pills
used today, and are usually more effective than progestin-only birth control pills.
