Lo Minastrin Fe is a prescription birth control pill that is taken once a day. Although most women do not develop any problems with this drug, side effects are possible and may include headaches, nausea, and spotting between periods. This combined oral contraceptive works by preventing ovulation, altering the cervical mucus, and changing the uterine lining.
What Is Lo Minastrin Fe?
Lo Minastrin™ Fe (norethindrone/ethinyl estradiol) is a prescription birth control pill. It was approved by the U.S. Food and Drug Administration (FDA) in July 2013. Lo Minastrin Fe provides a low dose of hormones compared with older birth control pills. It comes in chewable tablets and may be ideal for women who have difficulty swallowing tablets.
Lo Minastrin Fe is made by Warner Chilcott (US), LLC.
How Does Lo Minastrin Fe Work?
Lo Minastrin 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 Lo Minastrin Fe primarily prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries). However, this contraceptive also works to prevent pregnancy in two other minor ways. Lo Minastrin 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.
Each package of this contraceptive contains 24 tablets with both of the hormones, followed by 2 tablets with just the ethinyl estradiol but no norethindrone, followed by 2 inactive tablets that contain a small dose of 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 two days a month is questionable.
