Lybrel and Pregnancy

The FDA has classified Lybrel as a pregnancy Category X medication, which means that the contraceptive should not intentionally be used during pregnancy (as it may cause miscarriages or birth defects). It may be difficult to tell if you are pregnant while taking Lybrel, because you won't have regular monthly periods. However, if you accidentally take Lybrel before you realize you are pregnant, it probably won't cause any problems.

An Overview of Lybrel and Pregnancy

Lybrel™ (levonorgestrel/ethinyl estradiol) is a prescription birth control pill, also known as an oral contraceptive. As with all oral contraceptives, Lybrel should not intentionally be used during pregnancy. Keep in mind that women taking Lybrel do not have regular monthly periods, so it may be more difficult to detect a pregnancy if you are taking Lybrel (as there is no missed or late period).

Lybrel 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 the serious problems that could potentially occur (such as birth defects or miscarriages).
Even though Lybrel is a pregnancy Category X medication, it will probably not cause any problems if it is accidentally used during early pregnancy. Many studies have shown that there is no increased risk of birth defects when birth control pills are accidentally taken during early pregnancy.
Because you will not have a regular monthly period while taking Lybrel, make sure you are not pregnant any time you have reason to suspect you may be pregnant, especially if you have missed any pills. If you notice a sudden stop in your usual spotting and bleeding (which most women experience from time to time while on Lybrel), you might want to consider taking a pregnancy test.
If you accidentally used Lybrel for a while before you realized you were pregnant, this probably will not cause any problems (although you should discuss this with your healthcare provider). If you are pregnant, you should stop using Lybrel right away. If you think you may be pregnant, you should contact your healthcare provider for further instructions.
