Armodafinil - oral
Armodafinil - oral
Armodafinil reduces extreme sleepiness due to narcolepsy and other sleep disorders, such as periods of stopped breathing during sleep (obstructive sleep apnea). It is also used to help you stay awake during work hours if you have a work schedule that keeps you from having a normal sleep routine (shift work sleep disorder).
This medication does not cure these sleep disorders and may not get rid of all your sleepiness. Armodafinil does not take the place of getting enough sleep. It should not be used to treat tiredness or hold off sleep in people who do not have a sleep disorder.
It is not known how armodafinil works to keep you awake. It is thought to work by affecting certain substances in the brain that control the sleep/wake cycle.
Read the Medication Guide provided by your pharmacist before you start using armodafinil and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
For narcolepsy and obstructive sleep apnea, take this medication by mouth as directed by your doctor, usually once daily in the morning. If you are using armodafinil for shift work sleep disorder, take it as directed by your doctor, usually once a day 1 hour before you start your work shift. You may take this medication with or without food, but armodafinil may take longer to work if you take it with food.
If you are using this drug for sleep apnea, continue your other treatment (such as the CPAP machine, mouth device) unless your doctor tells you to stop.

Tell your doctor or pharmacist right away if you have withdrawal.
