You or your caregiver should tell your doctor immediately, if you experience any of the following symptoms: fast, pounding, or irregular heartbeat; sweating; dilated pupils; abnormally excited mood; irritability; restlessness; difficulty falling sleeping or staying asleep; hostility; aggression; anxiety; loss of appetite; loss of coordination; uncontrollable movement of a part of the body; flushed skin; vomiting; stomach pain; or thinking about harming or killing oneself or others or planning or trying to do so. Overusing dextroamphetamine may also cause serious heart problems or sudden death.

Tell your doctor if you or anyone in your family drinks or has ever drunk large amounts of alcohol, uses or has ever used street drugs, or has overused prescription medications. Your doctor will probably not prescribe dextroamphetamine for you.
Do not stop taking dextroamphetamine without talking to your doctor, especially if you have overused the medication. Your doctor will probably decrease your dose gradually and monitor you carefully during this time. You may experience depression and extreme tiredness if you suddenly stop taking dextroamphetamine after overusing it.
Do not sell, give away, or let anyone else take your medication. Selling or giving away dextroamphetamine is against the law and may harm others. Store dextroamphetamine in a safe place so that no one else can take it accidentally or on purpose. Keep track of how many tablets or capsules are left so you will know if any are missing.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with dextroamphetamine and each time you get more medication. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( Web Site) or the manufacturer's website to obtain the Medication Guide.
Dextroamphetamine is used as part of a treatment program to control symptoms of attention deficit hyperactivity disorder (ADHD; more difficulty focusing, controlling actions, and remaining still or quiet than other people who are the same age) in adults and children. Dextroamphetamine is also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). Dextroamphetamine is in a class of medications called central nervous system stimulants. It works by changing the amounts of certain natural substances in the brain.
Dextroamphetamine comes as a liquid, tablet, and an extended-release (long-acting) capsule to take by mouth. The tablet is usually taken 2 to 3 times daily with or without food. The extended-release capsule is usually taken once a day with or without food. The liquid is usually taken once or twice daily with or without food. Take dextroamphetamine at around the same time(s) every day. If you are taking dextroamphetamine tablets, take your first dose as soon as you wake up in the morning, and space your doses by 4 to 6 hours. Do not take dextroamphetamine in the evening because it may cause difficulty falling asleep or staying asleep. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take dextroamphetamine exactly as directed.
Do not chew or crush the extended-release capsules.
Your doctor will probably start you on a low dose of dextroamphetamine and gradually increase your dose, not more often than once every week.
Your doctor may tell you to stop taking dextroamphetamine from time to time to see if the medication is still needed. Follow these directions carefully.
Dextroamphetamine should not be used to treat excessive tiredness that is not caused by narcolepsy.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Unless your doctor tells you otherwise, continue your normal diet.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
