Minastrin™ 24 Fe (norethindrone/ethinyl estradiol) is a prescription oral contraceptive
(commonly known as a birth control pill
). It provides a low dose of hormones, compared with older birth control pills. Typically, women who take Minastrin 24 Fe have shorter, lighter periods. This drug comes in chewable tablets, and may be ideal for women with difficulty swallowing pills.
Minastrin 24 Fe is made by Catalent Pharma Solutions, LLC, for Warner Chilcott Company, Inc.
How Does Minastrin 24 Fe Work?
Minastrin 24 Fe is a combined oral contraceptive, which means it is a birth control pill that contains two different types of hormones. It contains both an estrogen (ethinyl estradiol) and a progestin (norethindrone). The hormones in Minastrin 24 Fe prevent pregnancy primarily by stopping ovulation (the maturation and release of eggs from the ovaries).
However, this contraceptive also works in two other, minor ways. Minastrin 24 Fe 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. It also alters the lining of the uterus (the endometrium), making it less receptive to an embryo.
Most birth control pills contain 21 active tablets with the hormones, followed by seven inactive tablets with no active ingredients. However, as the name suggests, there are 24 active tablets in Minastrin 24 Fe, three more than usual, with only four inactive tablets. Having fewer hormone-free days usually results in lighter, shorter periods.
The last four tablets, which contain no hormones, contain iron. The chemical symbol for iron is Fe. Taking these iron tablets may help prevent anemia due to blood loss during your period, although the actual benefit of taking iron for just four days a month is questionable.
