(dex troe am fet' a meen) (am fet' a meen)

IMPORTANT WARNING:

The combination of dextroamphetamine and amphetamine can be habit-forming. Do not take a larger dose, take the medication more often, or take it for a longer time than prescribed by your doctor. If you take too much dextroamphetamine and amphetamine, you may find that the medication no longer controls your symptoms, you may feel a need to take large amounts of the medication, and you may experience symptoms such as rash, difficulty falling asleep or staying asleep, irritability, hyperactivity, and unusual changes in your personality or behavior. Overusing dextroamphetamine and amphetamine may also cause sudden death or serious heart problems such as heart attack or stroke.

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 and amphetamine for you.

Do not stop taking dextroamphetamine and amphetamine 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 develop severe depression and extreme tiredness if you suddenly stop taking dextroamphetamine and amphetamine after overusing it.

Do not sell, give away, or let anyone else take your medication. Selling or giving away dextroamphetamine and amphetamine may harm others and is against the law. Store dextroamphetamine and amphetamine 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 amphetamine 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 (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.

WHY is this medicine prescribed?

The combination of dextroamphetamine and amphetamine 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 and amphetamine tablets are also used to treat narcolepsy (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). The combination of dextroamphetamine and amphetamine is in a class of medications called central nervous system stimulants. It works by changing the amounts of certain natural substances in the brain.

HOW should this medicine be used?

The combination of dextroamphetamine and amphetamine comes as a tablet and an extended-release (long-acting) capsule to take by mouth. The tablet is usually taken 2 to 3 times daily, 4 to 6 hours apart, with or without food. The extended-release capsule is usually taken once daily in the morning with or without food. Dextroamphetamine and amphetamine combination should not be taken in the late afternoon or 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 and amphetamine exactly as directed.

Swallow the extended-release capsules whole; do not chew or crush them. If you are unable to swallow the extended-release capsule, you may open the capsule and sprinkle the entire contents on a teaspoonful of applesauce. Swallow this mixture right away without chewing. Do not store the applesauce/medication mixture for future use, and do not divide the contents of one capsule into more than one dose.

Your doctor will probably start you on a low dose of dextroamphetamine and amphetamine and increase your dose gradually, not more often than once every week.

Your doctor may tell you to stop taking dextroamphetamine and amphetamine from time to time to see if the medication is still needed. Follow these directions carefully.

Are there OTHER USES for this medicine?

The combination of dextroamphetamine and amphetamine should not be used to treat excessive tiredness that is not caused by narcolepsy.

This medication may be prescribed for other conditions; ask your doctor or pharmacist for more information.
