Modafinil 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 help you stay awake during work hours for people with work schedules that interfere with a normal sleep routine (shift work sleep disorder-SWSD).
It is not known how modafinil works to increase wakefulness. It is thought to work by affecting certain chemicals in the brain that control the sleep/wake cycle. Modafinil does not make up for lack of sleep and should not be used to treat tiredness or hold off sleep in people who do not have a sleep disorder.
This medication is not recommended for use in children.
