Dextroamphetamine 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, 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; 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.

If you take too much dexmethylphenidate, you may continue to feel a need to take large amounts of the medication, and you may experience unusual changes in your behavior

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 (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) 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.

  • tell your doctor if you have glaucoma (increased pressure in the eye that may cause vision loss), hyperthyroidism (a condition in which you have too much thyroid hormone in your body); feelings of anxiety, tension, or agitation. Your doctor will probably tell you not to take dextroamphetamine.

  • tell your doctor if anyone in your family has or has ever had an irregular heartbeat or has died suddenly. Also tell your doctor if you have recently had a heart attack and if you have or have ever had a heart defect, high blood pressure, an irregular heartbeat, heart or blood vessel disease, hardening of the arteries, or other heart problems. Your doctor will examine you to see if your heart and blood vessels are healthy. Your doctor will probably tell you not to take dextroamphetamine if you have a heart condition or if there is a high risk that you may develop a heart condition.

  • tell your doctor if you or anyone in your family has or has ever had depression, bipolar disorder (mood that changes from depressed to abnormally excited), or mania (frenzied, abnormally excited mood), facial or motor tics (repeated uncontrollable movements), verbal tics (repetition of sounds or words that is hard to control) or Tourette's syndrome (a condition characterized by the need to perform repeated motions or to repeat sounds or words), or has thought about or attempted suicide. Also tell your doctor if you have or have ever had mental illness, seizures, or an abnormal electroencephalogram (EEG; test that measures electrical activity in the brain). If your child is taking dextroamphetamine to treat ADHD, tell your child's doctor if your child has recently experienced unusual stress.

  • tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking dextroamphetamine, call your doctor. Do not breastfeed while taking dextroamphetamine.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
