Key Information









It works for treating narcolepsy by acting as a stimulant to the brain.  The effects of Dexedrine are determined by numerous factors, such as body weight, other medical conditions, and other medications  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. These areas seem to be underactive in children with ADHD. It is thought increasing the activity of these chemicals improves the function of these underactive parts of the brain. We still don’t fully understand how stimulants work in children with ADHD, and they don’t work for everyone. But they can be very useful at helping some children to learn to control their behaviour.


Dexedrine come as either short-acting (usually 4 hours) or long-acting (6-12 hours) tablets. The shorter-acting medications effects take place in 20 minutes, while the longer-acting ones may take up to an hour before the effects begin to take place.  They are taken orally.

HEALTH RISKS (long term) which includes withdrawal & tolerance:

Tolerance to Dexedrine develops rapidly and users can use up to 50 times the therapeutic dose. Effects last for three to four hours. Withdrawal is divided into two phases - the immediate "crash" or rebound which lasts for two to three weeks and is characterised by hunger, extreme fatigue and long periods of fitful sleep. In the second phase, heavy users become irritable and depressed (sometimes severely). The second phase can last weeks and sometimes months.  Death from overdose is possible with large doses but rare. Overdose risk increases if Dexedrine is mixed with other depressant drugs such as opiates, barbiturates or alcohol.


Dexedrine  is a Class B drug.  Maximum penalties are five years in prison and/or a fine for possession or 14 years in prison and/or a fine for possession with intent to supply.

  1. Dexedrine is a central nervous system stimulant. It affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.
  2. Dexedrine is used to treat narcolepsy and attention deficit hyperactivity disorder (ADHD).
  3. Dexedrine produces increased wakefulness, energy and self-confidence in association with decreased fatigue and appetite.
  4. It belongs to the family of drugs known as psychostimulants.
  5. Dexedrine is highly addictive.
  6. Dexedrine is specifically an amphetamine that is included with the group of the central nervous system stimulants. This drug of choice was most commonly used back in the late 1960s and early 1970s as a dietary aid.
  7. Dexedrine is most commonly used by college students as a means to help them study, but also to get high.
  8. What the drug Dexedrine actually does is suppresses all spontaneous behaviour. This behaviour may include exploration or curiosity, socializing, and an increase in obsessive-compulsive behaviour
  9. Because it is a stimulant, this drug has high abuse potential. The stimulant effect may give way to a letdown period of depression and fatigue. Although the letdown can be relieved by taking another dose, this soon becomes a vicious circle.
  10. If you habitually take Dexedrine in doses higher than recommended, or if you take it over a long period of time, you may eventually become dependent on the drug and suffer from withdrawal symptoms when it is unavailable.
