PROVIGIL is a prescription medicine used to improve wakefulness in adults who experience excessive sleepiness (ES) due to one of the following diagnosed sleep disorders:
PROVIGIL could help you stay awake
PROVIGIL does not affect sleep for most patients*
PROVIGIL does not replace sleep and may not stop your ES completely.
*In clinical trials, some patients taking PROVIGIL (5%) reported trouble sleeping versus those patients who did not receive medication (placebo or sugar pill [1%]).
