Methylphenidate is used to treat attention disorders (attention deficit hyperactivity disorder, or ADHD) as part of a total treatment plan including psychological, educational and social measures. This medication is also used to treat patients with narcolepsy (a disorder of sleep regulation). When this medication is used to treat ADHD, patients may find they have increased attention, decreased impulsiveness, and decreased hyperactivity (see also Notes section). This medication is a mild stimulant that works by affecting the levels of chemicals (neurotransmitters) in the nervous system. This medication should not be used to treat simple fatigue symptoms.
