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.

Do not stop using your CPAP machine during sleep unless your doctor tells you to. The combination of treatment with CPAP and Provigil may be necessary to best treat your condition.
