Modaheal 200 is used to treat narcolepsy-related drowsiness as well as a number of other sleep disorders, including obstructive sleep apnea, or gasping for air while sleeping. If the sick person's typical sleep cycle is disrupted by the work schedule, a condition known as shift work sleep disorder, Modaheal may be prescribed to help them stay awake during work hours.
