What is Dexedrine (Dextroamphetamine Sulfate)?
Dexedrine (Dextroamphetamine Sulfate) belongs to a class of medications called stimulants, which are used to treat attention deficit disorder with or without hyperactivity (ADD / H) and narcolepsy (sleep attacks).
Dexedrine (Dextroamphetamine Sulfate) is used in the treatment of ADHD. It is used to reduce the mental and behavioral symptoms of ADHD, including limited attention span, impulsivity and hyperactivity.
How is Dexedrine (Dextroamphetamine Sulfate) supplied?
Dextroamphetamine spansule is supplied as follow: tablet 5mg, 10mg, 15mg
How does Dexedrine (Dextroamphetamine Sulfate) works
Dextroamphetamine increases the activity of chemicals (neurotransmitters) in the brain, ie dopamine and, to a lesser extent, norepinephrine. This drug stimulates the areas of the brain that regulate impulsivity, attention and movement, thus relieving the symptoms of ADHD.
Dextroamphetamine in children and adolescents
Health Canada has approved dextroamphetamine for the treatment of ADHD in adolescents and children six years of age and older.
Dextroamphetamine does not cure AD / HD. It aims to improve functional capacity by reducing the basic symptoms of AD / HD such as inability to pay attention, impulsivity and hyperactivity. Methylphenidate reduces these symptoms in about three-quarters of children and adolescents. It can also help you better tolerate frustrations and improve your relationships with others, including peers, and greatly improve your functional ability. Dextroamphetamine may also be more effective if combined with behavior management strategies (eg, rewarding good behavior, learning problem-solving skills).
Although dextroamphetamine does not produce any noticeable improvement at a young age, this does not mean that it will remain ineffective later in life.
When will dextroamphetamine begin to work?
Your doctor will slowly increase the dose of the drug to find the one that is most effective and produces the least possible side effects. The action of dextroamphetamine is felt during the first two days of use. Symptoms will begin to improve only when there is enough medicine in the body.
At the end of the day, when the medication stops working, the symptoms of AD / HD may come back. Your doctor will change the doses and when you take them according to your needs. For example, he may ask you to take a dose at a specific time so that there is enough medicine in your body while you study the main subjects in school (such as math), when you are experiencing more difficulty and transition periods (such as recess or when you drive home).
How long should I take Dexedrine (Dextroamphetamine Sulfate)?
The period during which people take dextroamphetamine varies. You should have an evaluation from time to time to determine whether you need it or not. Some people only need it at certain times in their lives, for example, when they attend school, and others continue to need it for many years. Your doctor may recommend that you stop taking it for a month, in the summer, to see if you still need it, promote your growth, and prevent your body from getting too used to the medicine.
Can Dexedrine (Dextroamphetamine Sulfate) be addictive?
When used as directed by your doctor, dextroamphetamine is not addictive. In general, people with AD / HD may have an increased risk of substance dependence in the long term. With effective treatment, they may be less vulnerable to this type of addiction than people who take no medication to manage their AD / HD.
What are the side effects of dextroamphetamine and what should I do if they occur?
Your doctor has prescribed dextroamphetamine because he believes that the benefits of this medicine outweigh the risks. However, like most medications, it can cause side effects, which are usually more common when you start taking them or when the dose is increased. Most are minor and almost always fade over time. You may also experience a side effect that seems serious or persistent. In this case, ask your doctor to suggest ways to reduce these side effects to your next appointment. Here are the most common side effects of this medicine, with parenthetical tips for reducing them.
More serious but uncommon side effects
Persistent pulsatile headache
Psychiatric symptoms: agitation; prolonged sadness; visual, auditory or tactile hallucinations; other unusual changes in mood (talk to your doctor)
Appearance or aggravation of vocal or motor tics; for example, shrugging, blinking of the eyes, rotation of the head, muscle spasms, throat clearing
Stunted (your doctor will monitor your growth and may change your treatment if needed)
Concerns have been raised about the possibility that dextroamphetamine increases the risk of heart problems in children and adolescents. However, studies have shown that the rate of sudden death (caused by a heart condition) is similar in children who take stimulant medications and in those who do not. Nevertheless, this possibility could be of concern for children who already have cardiac disease or malformation or who exercise vigorously. Dextroamphetamine should be used with caution in patients who are at increased risk for heart problems.
What precautions should I take when prescribed dextroamphetamine?
Several drugs may interact with dextroamphetamine, including some cough and cold medications, monoamine oxidase inhibitors such as selegiline (Eldepryl) or phenelzine (Nardil) and many others. If you are taking other prescription or over-the-counter medications, or if you are starting to take them, ask your doctor if you can do so safely. Your doctor may need to change the doses of your medications or monitor side effects more carefully if you are taking certain other medications.

You have heart disease or a family history of heart disease or sudden early death
You have a heart deformity or hardening of the blood vessels (atherosclerosis)

Do not let anyone else take your medicine.
What should I do if I forget to take a dose of dextroamphetamine?
