Loestrin Fe

Loestrin Fe is a type of birth control pill that works to prevent pregnancy by stopping ovulation, altering the cervical mucus, and changing the lining of the uterus. There is only one standard dosage of Loestrin Fe -- one tablet taken once a day, at the same time every day. Possible side effects include headaches, nausea, and breakthrough bleeding.

What Is Loestrin Fe?

Loestrin® Fe (norethindrone/ethinyl estradiol) is a prescription birth control pill (technically known as an oral contraceptive). The following generic birth control pills are equivalent to Loestrin Fe:
  • Gildess® Fe (made by Patheon, Inc., for Qualitest Pharmaceuticals USA)
  • Microgestin® Fe (made by Watson Pharmaceuticals, Inc.)
  • Junel® Fe (made by Teva Pharmaceuticals USA)
  • Larin™ Fe (made by Novast Laboratories Ltd. for Northstar Rx LLC).
Loestrin Fe is different from plain Loestrin® because it has 28 tablets in each pack and the last seven tablets contain iron (Loestrin has 21 tablets and does not contain iron). The information in this article does not apply to plain Loestrin.
Loestrin Fe is not the same as Loestrin® 24 Fe, a newer birth control pill that provides a shorter, lighter period. Similarly, it is not the same as Lo Loestrin® Fe, a very low-dose birth control pill. The information in this article does not apply to Loestrin 24 Fe or Lo Loestrin.
