Drug addiction is a possibility with dextroamphetamine. Never exceed the recommended dosage, frequency, or duration. Always follow your doctor’s instructions. If you take too much dextroamphetamine, you can continue to feel the need to take a lot of the drug, and your behaviour might shift in unexpected ways. If you have any of the following symptoms, you or your carer should call your doctor right away: heartbeat that is quick, pounding, or irregular; sweating; dilated pupils; an unusually ecstatic mood; irritability; restlessness; difficulty falling asleep 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 preparing, attempting, or even just having the thought of hurting or killing oneself or someone else. Dextroamphetamine abuse can result in fatal heart problems or sudden death.

If you take too much dexmethylphenidate, you can continue to feel the need to take a lot of the drug, and your behaviour might change in unexpected ways.

Inform your doctor if you or any members of your family regularly use excessive amounts of alcohol, use street drugs, or abuse prescription pharmaceuticals. Most likely, you won’t get a dextroamphetamine prescription from your doctor.

Without first consulting your doctor, do not discontinue taking dextroamphetamine, especially if you have been abusing the drug. Your dose will likely be gradually reduced by your doctor, who will also closely watch you during this period. If you abruptly cease using dextroamphetamine after an excessive amount of use, you might feel depression and intense fatigue.

Avoid sharing, selling, or allowing others to use your medication. Dextroamphetamine is illegal to sell or give away and could be harmful to other people. Dextroamphetamine should be kept in a secure location to prevent accidental or intentional consumption by others. Count the remaining tablets or capsules so you can identify any missing ones.

When you start therapy with dextroamphetamine and every time you acquire extra medication, your doctor or pharmacist will give you the manufacturer’s patient information leaflet (Medication Guide). If you have any questions, carefully read the material and contact your doctor or pharmacist. The Medication Guide is also available on the manufacturer’s website or the Food and Drug Administration (FDA) website (

Why is this medication prescribed?

For both adults and children, dextroamphetamine is used as part of a therapy plan to manage the signs and symptoms of attention deficit hyperactivity disorder (ADHD; greater trouble focusing, managing behaviours, and remaining still or quiet than other individuals their age). Also used to treat narcolepsy is dextroamphetamine (a sleep disorder that causes excessive daytime sleepiness and sudden attacks of sleep). The drug dextroamphetamine belongs to the group of drugs known as central nervous system stimulants. It functions by altering the concentrations of specific organic compounds in the brain.

How should this medicine be used?

Extended-release (long-acting) capsules, tablets, and liquid dextroamphetamine are all available for oral administration. Typically, 2 to 3 times a day, with or without food, the tablet is taken. Most people take the extended-release capsule once day, with or without food. Typically, the beverage is consumed once or twice a day, with or without meals. Dextroamphetamine should be taken every day at roughly the same time(s). Take your first dose of dextroamphetamine tablets as soon as you wake up in the morning and space subsequent doses by 4 to 6 hours if you’re taking them. Dextroamphetamine should not be consumed in the evening since it may make it difficult to fall or remain asleep. Ask your doctor or pharmacist to explain any instructions on your prescription label that you do not understand, and carefully follow their instructions. Just as prescribed, take dextroamphetamine.

The extended-release capsules should not be chewed or crushed.

Dextroamphetamine dosages are often started at modest levels and then gradually increased, usually no more than once per week, by your doctor.

Periodically, your doctor can advise you to stop taking dextroamphetamine in order to determine if you still require the drug. Pay close attention to these guidelines.

Other uses for this medicine

It is not recommended to use dextroamphetamine to treat excessive fatigue that is not brought on by narcolepsy.

Ask your doctor or pharmacist for more details if you believe this drug should be used for something else.

What special precautions should I follow?

Before taking dextroamphetamine,

  • If you have an allergy to dextroamphetamine, any other drugs, or any of the chemicals in dextroamphetamine preparations, let your doctor and pharmacist know right away. Get a list of the components from your pharmacist.
  • Inform your physician if you’re taking any of the following drugs or have stopped taking them within the previous 14 days: monoamine oxidase (MAO) inhibitors like tranylcypromine (Eldepryl), isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil), and selegiline (Eldepryl, Emsam) (Parnate). You should wait at least 14 days after stopping dextroamphetamine before starting an MAO inhibitor.

  • Inform your doctor if you have hyperthyroidism (a condition in which your body produces too much thyroid hormone), glaucoma (increased pressure in the eyes that may result in visual loss), or any sensations of anxiety, tension, or agitation. Most likely, your doctor will advise against taking dextroamphetamine.
  • Inform your doctor if anyone in your family has ever experienced a sudden death or has an abnormal heartbeat. A recent heart attack, heart defects, high blood pressure, an irregular heartbeat, heart or blood vessel illness, artery hardening, or any other cardiac issues should also be disclosed to your doctor. Your heart and blood vessels will be checked by your doctor during the examination. If you have a heart condition or there is a significant chance that you will develop a heart condition, your doctor will likely advise against taking dextroamphetamine.

Moreover, let your physician know whether you now or ever had a mental disorder, seizures, or an abnormal electroencephalogram (EEG; test that measures electrical activity in the brain). If your child is on dextroamphetamine to treat ADHD, let the doctor know if they have recently gone through any significant stress.
  • Inform your physician if you are nursing a baby, intend to get pregnant, or are already pregnant. Call your doctor if you become pregnant while taking dextroamphetamine. If you are using dextroamphetamine, avoid breastfeeding.
  • If you are 65 years of age or older, discuss the advantages and disadvantages of dextroamphetamine use with your doctor. Dextroamphetamine is often not recommended for usage by older persons since it is less safe than other drugs that can be used to treat the same illness.
  • Dextroamphetamine can make it challenging for you to accomplish tasks that call for alertness or fine motor coordination. Prior to understanding how this drug affects you, avoid using machinery or driving a car.
  • You should be aware that dextroamphetamine should be taken in conjunction with other therapies, such as counselling and specialised instruction, in order to effectively treat ADHD. Ensure that you adhere to all recommendations from your therapist or doctor.
