How should I take Nuvigil® (armodafinil)?
Take Nuvigil® exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Armodafinil may be habit-forming. Never share Nuvigil® with another person, especially someone with a history of drug abuse or addiction. Selling or giving away this medicine is against the law.

Nuvigil® is usually given for up to 12 weeks. Follow your doctor’s instructions.
If you are taking this medicine to treat sleepiness caused by obstructive sleep apnea, you may also be treated with a continuous positive airway pressure (CPAP) machine. This machine is an air pump connected to mask that gently blows pressurized air into your nose while you sleep. The pump does not breathe for you, but the gentle force of air helps keep your airway open to prevent obstruction.
Do not stop using your CPAP machine during sleep unless your doctor tells you to. The combination of treatment with CPAP and Nuvigil® may be necessary to best treat your condition.
Taking Nuvigil® does not take the place of getting enough sleep. Talk with your doctor if you continue to have excessive sleepiness even while taking this medicine. Nuvigil® will not cure obstructive sleep apnea or treat its underlying causes. Follow your doctor’s instructions about all your other treatments for this disorder.
