Adderall: 6 things you should know
Medically reviewed by C. Fookes, BPharm. Last updated on Jan 11, 2019.
1. How it works
- Adderall is a combination of four different amphetamine salts: dextroamphetamine saccharate, dextroamphetamine sulfate, amphetamine aspartate and amphetamine sulfate.
- Experts aren't sure exactly how Adderall works in Attention Deficit Hyperactivity Disorder (ADHD) but suggest it blocks the reuptake of the neurotransmitters, dopamine and norepinephrine, which increases their concentration in the neuronal synapse (the space between two nerves).
- Adderall belongs to the group of medicines known as central nervous system (CNS) stimulants.
- Used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD) to increase attention and decrease hyperactivity and impulsiveness.
- May be given to increase alertness in people with the sleep disorder, narcolepsy.
- When given for ADHD, Adderall should be used in conjunction with other treatment options, such as psychotherapy, education about the disorder, and social integration advice.
- FDA approved for children over the age of three.
- Adderall is available as a generic under the name mixed amphetamine salts (which may be abbreviated to MAS or M. amphet salts).
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- Insomnia (inability to sleep), headache, dry mouth, loss of appetite, nervousness, and nausea are the most common side effects.
- May also cause heart palpitations, constipation and other GI disturbances, weight loss, changes in libido, alopecia (hair loss), elevated blood pressure and muscle twitching, stiffness, or tightness.
- High potential for dependence especially when administered for long periods of time.
- High potential for abuse. May be sought after by drug abusers or people with addiction disorders. Misuse may cause sudden death or cardiovascular events. Overdosage has resulted in psychosis which is indistinguishable from schizophrenia.
- May exacerbate pre-existing psychiatric disorders such as bipolar disorder, psychotic disorder or mania; and increase anxiety, tension, and agitation.
- May impair judgment or reaction skills; exercise caution before driving or operating machinery until the full effects of Adderall are known.
- Reports indicate some temporary slowing of growth may occur when regular Adderall is given to children aged 7 through 10 years. Doctors should monitor height and weight and consider treatment interruption if growth suppression suspected.
- May increase the risk of seizures and peripheral circulatory problems and cause visual problems.
- May not be suitable for people with certain heart conditions, as the risk of sudden death is increased even with usual dosages. May also not be suitable for people with thyroid disease, glaucoma, psychiatric disease, a history of drug abuse, a tic disorder, seizures, or liver or kidney disease or circulation problems.
- May interact with a number of other drugs including other antidepressants, medications used to treat heart disease, blood thinners, decongestants, tramadol, and proton pump inhibitors.
- Extreme fatigue and depression have been reported when Adderall has been stopped suddenly, particularly in those who have been taking more than the recommended dose.
- Rare cases of priapism (painful erections more than 6 hours in duration) have been reported.
Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

- Take in the morning if using once daily. If using twice daily, avoid late evening dosages to reduce the risk of insomnia.
- May be taken with or without food.
- Take exactly as directed by your doctor and never increase the dosage without his or her advice.
- Ensure your child partakes in other psychological, educational, or social treatment measures as recommended by your doctor as these are also an important part of ADHD treatment.
- Do not suddenly stop taking Adderall, unless it is an emergency. Sudden discontinuation may precipitate a withdrawal reaction. Symptoms include extreme tiredness, depression, or agitation.
- Seek medical advice if symptoms persist or worsen despite treatment, or if psychotic symptoms (such as hearing voices or signs of paranoia) or hallucinations develop.
- Seek urgent medical help if you experience chest pain, shortness of breath or fainting while taking Adderall or other worrying symptoms such as unexplained nausea or vomiting or a fast heartbeat.
- Do not drive or operate machinery if Adderall impairs your judgment or reaction skills. Alcohol may contribute to these effects and should be avoided.
- Seek medical advice if any new numbness, pain, skin color change, sensitivity or unexplained wounds occur in your fingers or toes.
6. Response and Effectiveness
- Peak concentrations are reached within three hours following a single dose.
- Not all the hepatic enzymes involved in the metabolism of Adderall have been defined; however, CYP2D6 is known to be one of the enzymes responsible, which means that variations may occur in the way different individuals metabolize Adderall.
