The combination of dextroamphetamine and amphetamine can be habit-forming. Do not take a larger dose, take it more often, or take it for a longer time than prescribed by your doctor. If you take too much dextroamphetamine and amphetamine, you may continue to feel a need to take large amounts of the medication, and you may experience unusual changes in your behavior. 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; restlessness; irritability; 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 and amphetamine 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 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 ( Web Site) or the manufacturer's website to obtain the Medication Guide.

The immediate-release tablet (Adderall) is usually taken 2 to 3 times daily, 4 to 6 hours apart, with or without food.

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 and medication mixture for future use, and do not divide the contents of one capsule into more than one dose.
