Loestrin Fe Uses

How Does Loestrin Fe Work?

As mentioned, Loestrin Fe is a combined oral contraceptive because it contains a combination of two different types of hormones: an estrogen and a progestin. The hormones in Loestrin Fe prevent pregnancy primarily by stopping ovulation (the maturation and release of eggs from the ovaries).
Loestrin Fe also works to prevent pregnancy in two other, minor 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. It also alters the lining of the uterus (the endometrium), making it less receptive to an embryo.
The first 21 tablets in each pack of Loestrin Fe contain the active hormones. The last seven tablets do not contain any hormones, but they do contain iron. This iron may help replace the iron you lose when you have your period, which may help prevent anemia.

Loestrin Fe Uses in Children and Teens

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

Off-Label Loestrin Fe Uses

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