The active ingredient in the tablets is modafinil.
Modafinil can be taken by adults who suffer from
narcolepsy to help them to stay awake.
Narcolepsy is a condition that causes excessive
daytime sleepiness and a tendency to fall asleep
suddenly in inappropriate situations (sleep
attacks). Modafinil may improve your narcolepsy
and reduce the likelihood that you will have sleep
attacks but there may still be other ways that you
can improve your condition and your doctor will
advise you.
