How Does Dextroamphetamine Work?Dextroamphetamine is a stimulant, although it has effects that are opposite from what would be expected of a stimulant. While stimulants (like caffeine) can cause hyperactivity, this medication has a calming effect when used in the proper doses to treat ADHD. While the exact way dextroamphetamine produces a calming effect is not known, it is known to affect chemicals in the brain.
Dextroamphetamine is also licensed for narcolepsy treatment. Narcolepsy is a condition that involves falling asleep uncontrollably and at unusual times. People who have this condition often appear paralyzed while they are sleeping and have hallucinations when falling asleep. These people also often fall asleep several times during the day.
