Dexedrine

Dexedrine is a prescription drug licensed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Although Dexedrine is a stimulant, it can cause a calming effect when used in the proper doses to treat ADHD. The medication can cause an awakening effect when it's used to treat narcolepsy. Dexedrine comes in two forms -- tablets and Spansules. As with any medication, there are potential side effects of Dexedrine, which can include insomnia, weight loss, and changes in sex drive.

 

What Is Dexedrine?

Dexedrine® (dextroamphetamine sulfate) is a prescription medication that is used for the treatment of attention deficit hyperactivity disorder (ADHD). It is also used to treat narcolepsy. Dexedrine comes in two forms: tablets and Spansules®. Dexedrine Spansules are specially designed capsules that release the medication slowly over time. Dexedrine Spansules can be taken just once a day, eliminating the need to take the medication at school or work.
 
Because Dexedrine is a stimulant and is commonly abused, there are special rules for prescribing the medication (see Dexedrine: A Controlled Substance).
 
(Click Dexedrine Uses for more information on uses of Dexedrine, including possible off-label uses of the medication.)
 

Who Makes Dexedrine?

Dexedrine is manufactured by GlaxoSmithKline Corporation. Generic Dexedrine is made by several manufacturers.
 

How Does Dexedrine Work?

Dexedrine 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, Dexedrine has a calming effect when used in the doses to treat ADHD. While the exact way Dexedrine produces a calming effect is not known, it is known that Dexedrine affects chemicals in the brain.
 
Dexedrine is also licensed for narcolepsy treatment. Narcolepsy is a condition that involves falling asleep uncontrollably and at unusual times. People who have narcolepsy symptoms often appear paralyzed while they are sleeping and have hallucinations when falling asleep. People who have narcolepsy often fall asleep several times during the day.
 

Effects of Dexedrine

In clinical studies, Dexedrine has been shown to have a calming effect on children and teenagers with ADHD. Dexedrine helps them to focus and sit still. It also helps them to pay better attention and to improve their behavior. Dexedrine has also been shown to have awakening effects for people with narcolepsy.
 

When and How to Take Dexedrine

Some general considerations for when and how to take Dexedrine include the following:
 
  • Take Dexedrine tablets by mouth. Usually, you take them two or three times daily. Take the first dose of each day first thing in the morning. Take the next doses four to six hours apart.
     
  • Dexedrine Spansules should be taken once a day in the morning. Because Spansules are designed to dissolve slowly over time, they should not be crushed or chewed. It is important to swallow Dexedrine Spansules whole.
     
  • You may take Dexedrine with or without food. If Dexedrine bothers your stomach, try taking it with food.
     
  • For Dexedrine to work properly, it must be taken as prescribed. Dexedrine will not work if you stop taking it.
     

Dexedrine Dosing

The dose of Dexedrine recommended by your healthcare provider will vary depending on a number of factors, including:
 
  • The condition being treated (ADHD or narcolepsy)
  • Your age
  • Other medical conditions you may have
  • Other medications you may be taking.
     
As is always the case, do not adjust your dose unless your healthcare provider specifically instructs you to do so.

Side Effects of Dexedrine

As with any medicine, there are possible side effects with Dexedrine. However, not everyone who takes Dexedrine will experience side effects. In fact, most people tolerate Dexedrine well. When Dexedrine side effects do occur, they are often minor and either require no treatment or can easily be treated by you or your healthcare provider. Serious Dexedrine side effects are less common.
