What is Provigil® (modafinil) used for?
Provigil® is commonly used for treating excessive sleepiness due to narcolepsy and other sleep disorders, such as periods of stopped breathing during sleep (obstructive sleep apnea).

This medication does not cure these sleep disorders and may not get rid of all your sleepiness. Provigil® 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.
