STD Home > Estrostep Fe and Pregnancy

Due to the serious problems that could occur, Estrostep Fe should not intentionally be taken during pregnancy. Estrostep Fe has been classified as a pregnancy Category X medication by the FDA, but the birth control pill is unlikely to cause problems if you accidentally take it during early pregnancy. Estrostep Fe should be stopped immediately, however, once you realize you are pregnant.

Estrostep Fe During Pregnancy: An Overview

Estrostep® Fe (norethindrone/ethinyl estradiol) is a prescription oral contraceptive (one of the many available versions of "the pill"). As with any birth control pill, it is not a good idea to intentionally take Estrostep Fe during pregnancy. Although it is unlikely for a woman to become pregnant if she takes the drug correctly, the risk of pregnancy increases significantly if it is not taken correctly.
(Estrostep Fe is equivalent to Tri-Legest® Fe and Tilia™ Fe birth control pills. The information in this article also applies to Tri-Legest Fe and Tilia Fe.)

Estrostep Fe and Pregnancy Category X

The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category X is given to medications that should not be used during pregnancy, usually due to serious problems that could potentially occur, such as birth defects or miscarriages. A pregnancy Category X rating is the strongest indication that a medication should not be taken during pregnancy.
Although you may have heard that taking birth control pills during early pregnancy is dangerous, the truth is that doing so is not likely to cause any serious problems. Many studies have shown that there is no increased risk of birth defects when birth control pills were accidentally taken in early pregnancy. However, Estrostep Fe should never be taken intentionally during pregnancy, as there are no benefits to this. It should also not be used in an attempt to prevent or cause a miscarriage, as it is not effective for such uses.
