dextroamphetamine

If you miss a dose, take it as soon as you remember in the morning hours. If it is late in the afternoon or 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 provided by your pharmacist before you start using dextroamphetamine and each time you get a refill. If you have any questions, consult your doctor or pharmacist. Take this medication with or without food, usually when you first wake up in the morning or as directed by your doctor. If additional doses are prescribed, take them 4-6 hours apart. Taking this medication late in the day may cause trouble sleeping (insomnia). Swallow the capsules whole. Do not crush or chew them. Doing so may destroy the long action of the drug and may increase the risk of side effects. Use this medicine regularly exactly as your doctor prescribes in order to get the most benefit. To help you remember, take it at the same time(s) each day on the days that you take it. 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. If your symptoms persist or worsen, notify your doctor immediately. This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as severe tiredness, mood changes (e.g., 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. If you are taking this for ADHD, your doctor may recommend "drug holidays" when the medication is stopped for a short time to observe any changes in behavior.

Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for them.

Avoid taking MAO inhibitors (e.g., furazolidone, isocarboxazid, linezolid, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) within 2 weeks before, during, and after treatment with this medication. In some cases a serious (possibly fatal) drug interaction may occur. If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting this medication.
