Loestrin 24 Fe Uses

How Does Loestrin 24 Fe Work?

Loestrin 24 Fe is a combined oral contraceptive, which means that it is a birth control pill that contains two different types of hormones. It contains both an estrogen (ethinyl estradiol) and a progestin (norethindrone). Most importantly, the hormones in Loestrin 24 Fe prevent pregnancy by stopping ovulation (the maturation and release of eggs from the ovaries). However, it also works to prevent pregnancy in two other, less important ways. Loestrin 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. Lastly, Loestrin 24 Fe alters the lining of the uterus (called 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 Loestrin 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.

Loestrin 24 Fe Use in Children and Teens

Loestrin 24 Fe is approved for use in women of reproductive age. This means that it is not approved for use in girls who have not yet had their first menstrual period.

Off-Label Loestrin 24 Fe Uses

On occasion, your healthcare provider may recommend Loestrin 24 Fe for something other than contraception. This is called an "off-label" use. At this time, off-label Loestrin 24 Fe uses include the treatment of the following conditions:
  • Acne
  • Heavy menstrual bleeding
  • Painful menstrual periods
  • Irregular menstrual periods
  • Premenstrual dysphoric disorder (PMDD)
  • Various other problems, such as polycystic ovarian syndrome (PCOS).
