Contents of the pack and other information
1. WHAT DEXAMFETAMINE IS AND WHAT IT IS USED FOR
Dexamfetamine belongs to a group of medicines called stimulants. These work by increasing
activity in the brain. Dexamfetamine works by affecting some of the natural chemicals that
are found in the brain. In particular, it increases the activity of chemicals called dopamine
and noradrenaline in areas of the brain that play a part in controlling attention and behaviour.
Dexamfetamine stimulates activity in the brain, helping to keep people alert and active during
Dexamfetamine is used to treat:
• narcolepsy (being unable to stop yourself falling asleep)
• attention deficit hyperactivity disorder (ADHD) in children. Dexamfetamine may seem
an odd treatment for hyperactive children, as stimulants normally make people more active.
However, at the doses recommended for children with ADHD, Dexamfetamine can have the
opposite effect, helping some children to learn to control their behaviour.
