What is dexamphetamine?
Dexamphetamine is a stimulant drug, which means it speeds up the messages travelling between the brain and body.2
Dexamphetamine is a medication prescribed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy (a sleep disorder).1 Dexamphetamine is a Schedule 8 drug in Australia which means it is tightly controlled and requires a prescription.3
Dexamphetamine is also sometimes used by people without a prescription to increase alertness or to get ‘high’. You can buy aspen dexamfetamine sulfate here.

Prescribed stimulants work on the parts of the brain involved in regulating attention and arousal (being alert and awake). The medications can greatly improve concentration, impulse control and hyperactivity in about 80% of children with ADHD.8
In adults, attention deficit hyperactivity disorder is quite different —and the symptoms are unique for each individual.9 It is estimated that around 533,300 adults (aged 20+) have ADHD in Australia.10

Long-term effects
Regular use of dexamphetamine over a long-period has been linked to:
- cardiovascular complications
- reduced growth (weight and height) in children.13,14
Dexamphetamine and mental health
For some people, dexamphetamine use can lead to:
- increased anxiety
- trouble sleeping/insomnia
- psychosis/psychotic symptoms.18
The risk of experiencing psychosis or psychotic symptoms is higher when dexamphetamine isn’t taken as prescribed, especially for long periods at high doses. Psychosis is when someone loses the ability to distinguish between what is real and what isn’t real. It can includes symptoms such as paranoia, delusions, and hallucinations.19,20
If you have a history of anxiety, insomnia or psychosis, speak with your prescribing doctor about whether dexamphetamine is suitable.18
Tolerance and dependence
For people who take dexamphetamine as prescribed, they may feel they depend on them to manage their condition and/or regular functioning. It’s also possible to build up a tolerance, where they may feel like they need higher doses to manage their condition.21 If you have any concerns around tolerance or dependence, speak with your prescribing doctor.
People who regularly use dexamphetamine not as prescribed can develop tolerance and become dependent on the drug. You can buy aspen dexamfetamine sulfate here.
Mixing dexamphetamine with other drugs

- Dexamphetamine and other stimulants (speed, ice, caffeine, cocaine etc.): Combined stimulants increase strain on heart, anxiety & risk of stroke.
- Dexamphetamine and alcohol: may feel less intoxicated due to stimulant effects of amphetamine and lead to drinking more. Increases risk of alcohol poisoning.
- Dexamphetamine and tricyclic antidepressants/MAOI inhibitors: increased heart rate and blood pressure.22,23
