What is modafinil?
Modafinil is a medication that promotes wakefulness.
Modafinil is used to treat excessive sleepiness caused by sleep apnea, narcolepsy, or shift work sleep disorder.
Modafinil may also be used for purposes not listed in this medication guide.
You should not use modafinil if you have ever had an allergic reaction or skin rash while taking modafinil or armodafinil (Nuvigil).
Modafinil can cause skin reactions that may be severe enough to need treatment in a hospital. Stop taking this medicine and get emergency medical help if you have a skin rash or hives, blisters or peeling, mouth sores, trouble breathing or swallowing, fever, swelling in your legs, dark urine, yellowing of your skin or eyes, or swelling in your face.

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Modafinil can make certain birth control less effective. Hormonal contraception (birth control pills, injections, implants, skin patches, and vaginal rings) may not be effective enough to prevent pregnancy during your treatment. Talk with your doctor about the best methods of birth control to use while taking modafinil.
It is not known whether modafinil passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
