Provigil (modafinil) is a medication that promotes wakefulness. It is thought to work by altering the natural chemicals (neurotransmitters) in the brain.
Provigil is used to treat excessive sleepiness caused by sleep apnea, narcolepsy, or shift work sleep disorder.Provigil is usually taken each morning to prevent daytime sleepiness, or 1 hour before the start of a work shift to treat work-time sleep disorders.
If you are taking Provigil 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 a 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.(source: http://www.lowbudget-pharmacy.com)
