What Is Larin Fe Used For?

How Does This Contraceptive Work?

As mentioned, Larin Fe is a combined oral contraceptive that contains both an estrogen and a progestin. The hormones in Larin Fe prevent pregnancy primarily by stopping ovulation (the maturation and release of eggs from the ovaries).
Larin 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 Larin Fe contain the active hormones. The last seven tablets do not contain any hormones, but they do contain iron. This may help replace the iron you lose when you have your period, which may help prevent anemia. However, the benefit of taking iron for just seven days a month is questionable.

Can Children and Teens Use It?

Larin 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.

What About Off-Label Uses for Larin Fe?

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