amphetamine-dextroamphetamine

If you miss a dose, use it as soon as you remember in the morning hours. If it is after noon, or if it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not double the dose to catch up.

Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking amphetamine/dextroamphetamine and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth with or without food, usually once daily in the morning or as directed by your doctor. Taking this medication after noon may cause trouble sleeping. Swallow the capsules whole. Do not crush or chew the capsules. Doing so can destroy the long action of the drug and increase side effects. If you have difficulty swallowing this medication whole, you may sprinkle the entire contents of a capsule on a small amount of applesauce just before taking. Swallow the mixture immediately. Do not chew the mixture, and do not save it for future use. Drink a glass of liquid after each dose. The dosage is based on your medical condition and response to therapy. Your doctor may adjust your dose to find the dose that is best for you. Follow your doctor's instructions carefully. Use this medication regularly and exactly as prescribed in order to get the most benefit from it. To help you remember, use it at the same time each day. This medication may cause withdrawal reactions, especially if it has been used regularly for a long time (more than a few weeks) or in high doses. In such cases, withdrawal symptoms (such as severe tiredness, mood changes including depression, and sleep problems) may occur if you suddenly stop using this medication. To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions immediately. Though it is unlikely to occur, this medication can also result in abnormal drug-seeking behavior (addiction/habit-forming). Do not increase your dose, take it more frequently or use it for a longer period of time than prescribed. Properly stop the medication when so directed. This will lessen the chances of becoming addicted. When used for a long period, this medication may not work as well and may require different dosing. Talk with your doctor if this medication stops working well. If you are taking this drug for ADHD, your doctor may recommend "drug holidays" when the medication is stopped for a short time to observe any changes in behavior. Inform your doctor if your condition does not improve or if it worsens.
