Junel Fe™ (norethindrone/ethinyl estradiol) can potentially interact with several other medicines. These interactions can be severe enough to cause accidental pregnancy, and a backup method of birth control may be recommended in many cases. If you are taking any medication that interacts with Junel Fe and increases the risk of pregnancy, check with your healthcare provider about how long to use a backup method of birth control (it may be longer than you would guess).
(Junel Fe is a generic version of Loestrin® Fe and is also equivalent to Microgestin® Fe birth control pills. The information in this article also applies to both of these medications.)
