Tri-Norinyl and Pregnancy

If you are using Tri-Norinyl and pregnancy occurs, you should immediately stop taking the birth control pill. The FDA has classified Tri-Norinyl as a pregnancy Category X medication, meaning that it could cause serious problems if taken during pregnancy (such as birth defects). However, many studies have shown that if you accidentally take Tri-Norinyl before you realized you were pregnant, it probably won't cause any problems.

An Overview of Tri-Norinyl and Pregnancy

Tri-Norinyl® (norethindrone/ethinyl estradiol) is a prescription birth control pill, one of the many versions of "the pill" that are currently available. Women who are pregnant should not intentionally take Tri-Norinyl (or any other birth control pill). Although it is unlikely for a woman to become pregnant if she takes Tri-Norinyl correctly, the risk of pregnancy significantly increases if Tri-Norinyl is not taken exactly as directed.
 
(Tri-Norinyl is equivalent to Aranelle™ and Leena® birth control pills. The information in this article also applies to each of these medications.)
 

Tri-Norinyl and Pregnancy Category X

The U.S. Food and Drug Administration (FDA) uses a pregnancy 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 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 it is "common knowledge" that taking birth control pills during early pregnancy is very dangerous, the truth is that doing so is probably unlikely to cause any serious problems. Even though Tri-Norinyl is a pregnancy Category X medication, many studies have shown that there is no increased risk of birth defects when birth control pills are accidentally taken during early pregnancy. However, Tri-Norinyl should never intentionally be taken during pregnancy. It should not be used in an attempt to prevent or cause a miscarriage, as it is not effective for such uses.
