Modalert is an anti-drowsiness medicine used to treat persons with narcolepsy, whether or not they have cataplexy, or who have a sleep disturbance due to working night or rotating shifts and are unable to sleep at night. Modalert 200 is also referred to as a wakefulness aid.
If you have narcolepsy, a disease in which you have many sleep episodes during the day or fall asleep in strange settings, Modalert can help you stay awake.
