Dexedrine (Dextroamphetamine)
Patient Information

Pronounced: DEX-eh-dreen
Generic name: Dextroamphetamine sulfate

Why is Dexedrine prescribed?

Dexedrine, a stimulant drug available in tablet or sustained-release capsule form, is prescribed to help treat the following conditions:

Narcolepsy (recurrent "sleep attacks")
Attention Deficit Hyperactivity Disorder. (The total treatment program should include social, psychological, and educational guidance along with Dexedrine.)

Most important fact about Dexedrine

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.

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.

How should you take Dexedrine?

Take Dexedrine exactly as prescribed. If it is prescribed in tablet form, you may need up to 3 doses a day. Take the first dose when you wake up; take the next 1 or 2 doses at intervals of 4 to 6 hours. You can take the sustained-release capsules only once a day.

Do not take Dexedrine late in the day, since this could cause insomnia. If you experience insomnia or loss of appetite while taking this drug, notify your doctor; you may need a lower dosage.

It is likely that your doctor will periodically take you off Dexedrine to determine whether you still need it.

Do not chew or crush the sustained-release form, Dexedrine Spansules.

Do not increase the dosage, except on your doctor's advice.

Do not use Dexedrine to improve mental alertness or stay awake. Do not share it with others.

--If you miss a dose...

If you take 1 dose a day, take it as soon as you remember, but not within 6 hours of going to bed. If you do not remember until the next day, skip the dose you missed and go back to your regular schedule.

If you take 2 or 3 doses a day, take the dose you missed if it is within an hour or so of the scheduled time. Otherwise, skip the dose and go back to your regular schedule. Never take 2 doses at once.

--Storage instructions...

Store at room temperature in a tightly closed container, away from light.

What side effects may occur when taking Dexedrine?

Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Dexedrine.

More common side effects of Dexedrine may include: Excessive restlessness, overstimulation
Other side effects may include: Changes in sex drive, constipation, diarrhea, dizziness, dry mouth, exaggerated feeling of well-being or depression, headache, heart palpitations, high blood pressure, hives, impotence, loss of appetite, rapid heartbeat, sleeplessness, stomach and intestinal disturbances, tremors, uncontrollable twitching or jerking, unpleasant taste in the mouth, weight loss
Effects of chronic heavy abuse of Dexedrine may include: Hyperactivity, irritability, personality changes, schizophrenia-like thoughts and behavior, severe insomnia, severe skin disease

Why should this drug not be prescribed?

Do not take Dexedrine if you are sensitive to or have ever had an allergic reaction to it.

Do not take Dexedrine for at least 14 days after taking a monoamine oxidase inhibitor (MAO inhibitor) such as the antidepressants Nardil and Parnate. Dexedrine and MAO inhibitors may interact to cause a sharp, potentially life-threatening rise in blood pressure.

Your doctor will not prescribe Dexedrine for you if you suffer from any of the following conditions:

Agitation
Cardiovascular disease
Glaucoma
Hardening of the arteries
High blood pressure
Overactive thyroid gland
Substance abuse

Dexedrine may impair judgment or coordination. Do not drive or operate dangerous machinery until you know how you react to the medication.

There is some concern that Dexedrine may stunt a child's growth. For the sake of safety, any child who takes Dexedrine should have his or her growth monitored.
