(dex troe am fet' a meen)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 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 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.
