Armodafinil decreases extreme sleepiness due to narcolepsy and other sleep disorders such as difficult/irregular breathing during sleep (e.g., obstructive sleep apnea/hypopnea syndrome-OSAHS). It is also used to decrease sleepiness due to work schedules that interfere with a normal sleep routine (shift work sleep disorder-SWSD).
It is not known how armodafinil works to increase wakefulness. It is thought to work by affecting certain substances in the brain that control the sleep/wake cycle. Armodafinil does not make up for lack of sleep. It should not be used to treat tiredness or hold off sleep in people who do not have a sleep disorder.
