What is ASPEN DEXAMFETAMINE
The active ingredient is called dexamfetamine sulfate which belongs to a group of medicines called central nervous system stimulants and is a sympathomimetic amine of the amphetamine group.
It is used to treat a number of medical conditions.
- Hyperkinetic behaviour disorders in children. This behavioural disorder is also known as Attention-deficit Hyperactivity Disorder (ADHD). Not all people with this disorder are hyperactive, which affects the ability to concentrate on tasks for any length of time.
Children suffering from ADHD may have trouble learning or doing school work, and may become aggressive or unmanageable at school or at home. ASPEN DEXAMFETAMINE helps focus attention and shuts out distraction, allowing the child to concentrate.
- Narcolepsy (a sleep disorder). People with narcolepsy have recurring attacks of irresistible day-time sleepiness in spite of a good night’s sleep.
Because of the liability for abuse, drugs of the amphetamine type are subject to special restrictions on their availability. Prescriptions for this substance may require validation by State or Territory Health Departments or Commissions.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed this medicine for another purpose.
If you have any concerns, you should discuss this with your doctor.
This medicine is available only with a doctor’s prescription.
