Provigil, also known as modafinil, is a prescription medication that falls into the wakefulness-promoting agent class of drugs. It is approved for the treatment of wakefulness disorders such as narcolepsy, shift work sleep disorder and excessive daytime sleepiness associated with obstructive sleep apnea. However, Provigil does not cure these sleep disorders, and though it may assist with sleepiness, it does not necessarily eliminate the feeling - nor does it take the place of sleep.
