Armodafinil and Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Armodafinil falls into category C.  In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Hormonal birth control methods may not work while you take armodafinil tablets. Women who use one of these methods of birth control may have a higher chance for getting pregnant while taking armodafinil tablets, and for one month after stopping armodafinil tablets. Talk to your doctor about birth control choices that are right for you while taking armodafinil tablets.

Armodafinil and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed.

It is not known if armodafinil crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using armodafinil.
