New regulations state that Modalert 200 mg can only be prescribed to people with clinically diagnosed narcolepsy or related conditions. Narcolepsy is a neurological disorder that affects the brain’s ability to regulate the sleep-wake cycle, causing excessive daytime sleepiness, sudden muscle weakness (cataplexy), and uncontrollable sleep episodes. For people with this condition, Modalert is a lifeline, enabling them to function more normally and maintain a regular daily routine.
