Pregnancy and Breast-feeding Warnings [top]

Pregnancy Warning

Dextroamphetamine caused harm in animal studies including decreased survival, and irreversible nerve fiber damage. In women, prenatal exposure to amphetamines is associated with an increased risk of premature delivery, low birth weight and withdrawal symptoms in the newborn. Women taking amphetamines or dextroamphetamine should talk to their doctor about alternative treatments.

Breast-feeding Warning

Amphetamines are excreted in human breast milk. Because of the potential for adverse events including increased irritability, agitation, and crying in nursing infants, women taking amphetamines or dextroamphetamine should talk to their doctor about discontinuing the drug or discontinuing nursing.

Safety Warnings For This Drug [top]





Sudden death has been reported in association with amphetamine treatment at usual doses in children with structural cardiac abnormalities or other serious heart problems. Adderall generally should not be used in children or adults with structural cardiac abnormalities or other serious heart problems.

Drug treatment is not suitable for all children with attention deficit hyperactivity disorder (ADHD). Drug treatment is not intended for use in patients who exhibit symptoms of the disorder that result primarily from environmental factors (school, home), learning disabilities and/or other psychiatric disorders, including psychosis.


Amphetamines have a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants, including amphetamines, can result in overdose and death, and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.

Before prescribing amphetamines, assess each patient’s risk for abuse, misuse and addiction. Educate patients and their families about these risks, as well as about proper storage of the drug and proper disposal of any unused drug. Throughout amphetamine treatment, reassess each patient’s risk of abuse, misuse and addiction and frequently monitor for signs and symptoms of abuse, misuse and addiction.[2]

Facts About This Drug [top]

Amphetamine (ADDERALL XR) and dextroamphetamine (DEXEDRINE) are approved by the Food and Drug Administration (FDA) to treat symptoms of attention-deficit hyperactivity disorder (ADHD) and narcolepsy, a rare sleep disorder. Amphetamine and dextroamphetamine are, for all practical purposes, the same drug.

Amphetamine, like many drugs, is a mixture of chemically identical compounds that are mirror images of each other. One of the compounds that make up amphetamine is dextroamphetamine....

Amphetamine (ADDERALL XR) and dextroamphetamine (DEXEDRINE) are approved by the Food and Drug Administration (FDA) to treat symptoms of attention-deficit hyperactivity disorder (ADHD) and narcolepsy, a rare sleep disorder. Amphetamine and dextroamphetamine are, for all practical purposes, the same drug.

Amphetamine, like many drugs, is a mixture of chemically identical compounds that are mirror images of each other. One of the compounds that make up amphetamine is dextroamphetamine. Separating these mirror images, or recombining them, and selling the combination as a “new” drug is a successful business scheme to protect patents, not a strategy to improve public health.

Amphetamine and dextroamphetamine belong to a family of central nervous system stimulant drugs sometimes called psychostimulants. Amphetamine and dextroamphetamine affect the neurotransmitters dopamine and norepinephrine.[3] Exactly how these drugs work is not fully known. Amphetamines may control the symptoms of some conditions but are not a cure for any condition.[4]

Amphetamine and dextroamphetamine are classified as Schedule II controlled substances by federal law. Misuse can result in criminal charges. All children prescribed amphetamine should be cautioned not to share or sell their medications. Each new and refill prescription requires a new, handwritten prescription. If your child is taking more than one dose a day, ask your pharmacist to divide your prescription into two labeled containers: one for home and one for school or work. Check with schools about their security procedures. Be sure that refill requests correspond to the time for the amount prescribed.

If you are subject to urine tests for employment or school, inform the appropriate parties that you take an amphetamine medication.

People with uncontrolled high blood pressure should not take any amphetamine.[5] This includes patients with mild high blood pressure.[6]

Periodically, your doctor should reassess your need to continue taking amphetamines.

Adverse effects

Psychiatric symptoms

Drugs used to treat ADHD present a slightly increased risk of drug-related psychiatric symptoms, such as hearing voices, mania or unprovoked suspiciousness, even in patients who did not have previous psychiatric problems.

In 2015, Health Canada, an agency similar to the FDA, updated the warning section of the labels of drugs used to treat ADHD on the risk of suicidal thoughts and behaviors. The advisory stated that Health Canada had received reports that included thoughts of suicide, suicide attempts and, in a very small number of cases, completed suicide. [7]

FDA black-box warning: heart problems and other warnings

These drugs’ labels include a black-box warning informing patients about the risk of drug dependence, sudden death and serious cardiovascular problems associated with these drugs (see "FDA Black-Box Warning" at the top of this page).

However, the statement “Misuse of amphetamines may cause sudden death and serious cardiovascular adverse events,” which appears in the black-box warning, is extremely misleading because it does not tell patients that the drugs also can cause sudden death in those using the medication properly. Sudden death has been reported in association with the use of stimulant ADHD drugs in children, adolescents and adults with structural heart abnormalities or other serious heart problems (such as heart valve disease or abnormal heart rhythm), even when these patients take the recommended doses. The FDA should immediately take steps to change the last statement in the black-box warning to say that sudden death and serious complications can occur in a wide variety of people who are not misusing the drugs.

Children, adolescents and adults who are being considered for treatment with stimulant drugs for ADHD should have a careful medical history assessment, including assessment for a family history of sudden death or heart rhythm disturbance. Patients should undergo a physical examination to assess for the presence of heart disease.[1]

FDA Medication Guide

Amphetamine and dextroamphetamine are among the limited number of drugs for which the FDA requires an FDA-approved Medication Guide to be dispensed when the prescription is filled or refilled.

The FDA-approved Medication Guides for amphetamine and dextroamphetamine alert patients to the possible cardiovascular and psychiatric risks associated with the medicines and describe precautions that can be taken to help patients use these medications more safely.[8]

Serotonin syndrome[9]

Serotonin syndrome (excess serotonin) is a life-threatening condition that occurs when two or more drugs that have an effect on serotonin are taken together. Symptoms of serotonin syndrome include:

  • Restlessness
  • Hallucinations
  • Loss of coordination
  • Fast heartbeat
  • Increased body temperature
  • Rapid changes in blood pressure
  • Overactive reflexes
  • Diarrhea
  • Coma
  • Nausea
  • Vomiting

Regulatory actions surrounding amphetamines

2010: The FDA updated the drug information label for amphetamines to include information on the coadministration of proton pump inhibitors and amphetamine medications. The advisory stated that patients taking this combination therapy should be monitored for changes in the clinical effect of amphetamine.[10]

2013: The FDA issued an advisory that, in post-marketing reports, treatment with dextroamphetamine and mixed amphetamine is associated with peripheral vasculopathy (damage to blood vessels outside of the heart), including Raynaud’s phenomenon. These disorders typically affect the fingers and toes. Raynaud’s phenomenon is characterized by a pale to blue to red sequence of color changes of the fingers or toes, most commonly after exposure to cold. The fingers or toes also may feel numb or painful.[11]

2023: The FDA announced it is requiring drug manufacturers to update the boxed warning on the misuse and abuse of stimulant drugs.[12]
