            Warnings

            Black Box Warnings

            This medication has a high potential for abuse and misuse, which can lead to development of substance use disorder, including addiction; misuse and abuse of CNS stimulants 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 this medication, assess each patient’s risk for abuse, misuse, and addiction; educate patients and their families about risks, proper storage of the drug, and proper disposal of any unused drug

            Throughout treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction

            Contraindications

            Hypersensitivity to drug or components

            Hyperthyroidism

            Glaucoma

            Hypertension, advanced arteriosclerosis, symptomatic CVD

            Agitated states, history of drug abuse

            Within 14 days of administering MAOIs

            Cautions

            Risk of adverse psychiatric events; eg, hallucinations and mania

            Caution in mild hypertension

            Associated with peripheral vasculopathy, including Raynaud phenomenon

            Difficulties with accommodation and blurring of vision have been reported with stimulant treatment

            Patients who develop symptoms such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease during stimulant treatment should undergo a prompt cardiac evaluation

            Particular care should be taken in using stimulants to treat ADHD patients with comorbid bipolar disorder because of concern for possible induction of mixed/manic episode in such patients

            Aggressive behavior or hostility is often observed in children and adolescents with ADHD; monitor for the appearance of or worsening of aggressive behavior or hostility

            Monitor growth of children ages 7 to 10 years during treatment with stimulants; may need to interrupt therapy in patients not growing or gaining weight as expected

            Stimulants may lower convulsive threshold in patients with prior history of seizure, patients with prior EEG abnormalities in absence of seizures, and very rarely, patients without a history of seizures and no prior EEG evidence of seizures; discontinue therapy in the presence of seizures

            Use with caution in patients who use other sympathomimetic drugs

            Rare instances of prolonged and sometimes painful erections (priapism), sometimes requiring surgical intervention, reported with methylphenidate products; typically not reported during initiation, but often subsequent to an increase in dose; seek immediate medical attention for abnormally sustained or frequent and painful erections

            Abuse, misuse, and addiction

            • This medication has a high potential for abuse and misuse; use exposes individuals to risks of abuse and misuse, which can lead to development of a substance use disorder, including addiction; this medication can be diverted for non-medical use into illicit channels or distribution
            • Risk of overdose and death is increased with higher doses or unapproved methods of administration, such as snorting or injection
            • Educate patients and their families about abuse, misuse, and addiction and proper disposal of any unused drug; advise patients to store amphetamine sulfate in a safe place, preferably locked, and instruct patients to not give medication to anyone else; throughout treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction

            Increased blood pressure and heart rate

            • CNS stimulants cause an increase in blood pressure (mean increase about 2 to 4 mm Hg) and heart rate (mean increase about 3 to 6 bpm
            • Monitor all patients for potential tachycardia and hypertension

            Risks to patient with serious cardiac disease

            • Sudden death reported in patients with structural cardiac abnormalities or other serious cardiac disease treated with CNS stimulant treatment at recommended ADHD dosages
            • Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease

            Motor and verbal tics, and worsening of Tourette’s Syndrome

            • CNS stimulants, including amphetamine sulfate, associated with onset or exacerbation of motor and verbal tics; worsening of Tourette’s syndrome also reported
            • Before initiating therapy, assess family history and clinically evaluate patients for tics or Tourette’s syndrome; regularly monitor patients for emergence or worsening of tics or Tourette’s syndrome with therapy, and discontinue treatment if clinically appropriate

            Drug interaction overview

            • Serotonin syndrome, a potentially life-threatening reaction, may occur when amphetamines are used in combination with other drugs that affect the serotonergic neurotransmitter systems such as monoamine oxidase inhibitors (MAOIs), selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John’s Wort
            • Amphetamines are known to be metabolized, to some degree, by cytochrome P450 2D6 (CYP2D6) and display minor inhibition of CYP2D6 metabolism; potential for a pharmacokinetic interaction exists with coadministration of CYP2D6 inhibitors which may increase risk with increased exposure to amphetamines; in these situations, consider alternative non-serotonergic drug or alternative drug that does not inhibit CYP2D6
            • If concomitant use with other serotonergic drugs or CYP2D6 inhibitors is clinically warranted, initiate therapy with lower doses, monitor patients for emergence of serotonin syndrome during drug initiation or titration, and inform patients of increased risk for serotonin syndrome

            Pregnancy & Lactation

            Pregnancy

            While there are no adequate and well-controlled studies in pregnant women, there has been 1 report of severe congenital bony deformity, tracheoesophageal fistula, and anal atresia (VATERassociation) in baby born to woman who took dextroamphetamine sulfate with lovastatin during first trimester of pregnancy

            This drug should be used during pregnancy only if potential benefit justifies potential risk to fetus

            Infants born to mothers dependent on amphetamines have increased risk of premature delivery and low birth weight

            Also, these infants may experience symptoms of withdrawal as demonstrated by dysphoria, including agitation, and significant lassitude

            Animal data

            • Therapy shown to have embryotoxic and teratogenic effects when administered to A/Jax mice and C57BL mice in doses approximately 41 times maximum human dose; embryotoxic effects were not seen in New Zealand white rabbits given drug in doses 7 times the human dose nor in rats given 12.5 times maximum human dose

            Lactation

            Amphetamines are excreted in human milk; mothers taking amphetamines should be advised to refrain from nursing

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            Absorption

            Peak plasma time: ~3 hr (immediate release); ~8 hr (sustained release)

            Onset of action: 1-1.5 hr

            Metabolism

            Hepatic via glucuronidation and mono-oxygenase

            Elimination

            Half-life: 7-24 hr, dependent on urinary pH

            Half-life elimination: 10-13 hr (adults)

            Excretion: Urine

            DEXTROAMPHETAMINE SUSTAINED-ACTION CAPSULE - ORAL

            (DEX-troe-am-FET-a-meen)

            COMMON BRAND NAME(S): Dexedrine

            WARNING: Misuse or abuse of amphetamines may cause serious (possibly fatal) heart and blood pressure problems. Amphetamine-type medications can be habit-forming. Use only as directed. If you use this drug for a long time, you may become dependent on it and may have withdrawal symptoms after stopping the drug. Consult your doctor or pharmacist for more details. (See also How to Use section).

            USES: This medication is used to treat attention deficit hyperactivity disorder - ADHD. It works by changing the amounts of certain natural substances in the brain. Dextroamphetamine belongs to a class of drugs known as stimulants. It can help increase your ability to pay attention, stay focused on an activity, and control behavior problems. It may also help you to organize your tasks and improve listening skills.This drug is also used to treat a certain sleeping disorder (narcolepsy) to help you stay awake during the day. It should not be used to treat tiredness or to hold off sleep in people who do not have a sleep disorder.

            HOW TO USE: Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking dextroamphetamine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth with or without food as directed by your doctor, usually 1-3 times a day. The first dose is usually taken when you wake up in the morning. If more doses are prescribed, take them as directed by your doctor, usually 4-6 hours apart. Taking this medication late in the day may cause trouble sleeping (insomnia).The dosage is based on your medical condition and response to treatment. Your doctor may adjust your dose to find the dose that is best for you. Follow your doctor's instructions carefully.Swallow the capsules whole. Do not crush or chew the capsules. Doing so can release all of the drug at once, increasing the risk of side effects.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.During treatment, your doctor may occasionally recommend stopping the medication for a short time to see whether there are any changes in your behavior and whether the medication is still needed.If you suddenly stop using this medication, you may have withdrawal symptoms (such as severe tiredness, sleep problems, mental/mood changes such as depression). To help prevent withdrawal, your doctor may lower your dose slowly. Withdrawal is more likely if you have used dextroamphetamine for a long time or in high doses. Tell your doctor or pharmacist right away if you have withdrawal.Though it helps many people, this medication may sometimes cause addiction. This risk may be higher if you have a substance use disorder (such as overuse of or addiction to drugs/alcohol). Do not increase your dose, take it more often, or use it for a longer time than prescribed. Properly stop the medication when so directed.When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.Tell your doctor if your condition does not improve or if it worsens.

            SIDE EFFECTS: Nausea, stomach upset, cramps, loss of appetite, diarrhea, dry mouth, headache, nervousness, dizziness, trouble sleeping, sweating, weight loss, irritability, and restlessness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.Tell your doctor right away if you have any serious side effects, including: signs of blood flow problems in the fingers or toes (such as coldness, numbness, pain, or skin color changes), unusual wounds on the fingers or toes, mental/mood/behavior changes (such as agitation, aggression, mood swings, depression, hallucinations, abnormal thoughts/behavior, thoughts of suicide), uncontrolled movements, muscle twitching/shaking, outbursts of words/sounds, change in sexual ability/interest, swelling ankles/feet, extreme tiredness, significant unexplained weight loss, frequent/prolonged erections (in males).Get medical help right away if you have any very serious side effects, including: shortness of breath, chest/jaw/left arm pain, severe headache, fast/pounding/irregular heartbeat, seizures, weakness on one side of the body, trouble speaking, confusion, fainting, blurred vision.This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.

            PRECAUTIONS: Before taking this medication, tell your doctor or pharmacist if you are allergic to it; or to other sympathomimetic drugs (such as amphetamine or lisdexamfetamine); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: blood circulation problems (such as Raynaud's disease), certain mental/mood conditions (such as severe agitation, psychosis), personal/family history of mental/mood disorders (such as bipolar disorder, depression, psychotic disorder, suicidal thoughts), heart problems (including irregular heartbeat/rhythm, coronary artery disease, heart failure, cardiomyopathy, problems with the heart structure such as valve problems), family history of heart problems (such as sudden death/irregular heartbeat/rhythm), history of stroke, high blood pressure, overactive thyroid (hyperthyroidism), history of heart attack or stroke, a certain eye problem (glaucoma), seizures, personal or family history of a substance use disorder (such as overuse of or addiction to drugs/alcohol), personal or family history of uncontrolled muscle movements (such as Tourette's syndrome).This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Children may be more sensitive to the side effects of this drug, especially weight loss. This medication may slow down a child's growth. The doctor may recommend temporarily stopping the medication from time to time to reduce this risk. Monitor your child's weight and height. Consult your doctor or pharmacist for more details.Older adults may be more sensitive to the side effects of this drug, especially chest pain, trouble sleeping, or weight loss.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor. Infants born to mothers who are dependent on this medication may be born too soon (premature) and have low birth weight. They may also have withdrawal symptoms. Tell your doctor right away if you notice possible mood changes, agitation, or unusual tiredness in your newborn.This medication passes into breast milk and may have undesirable effects on a nursing infant. Breast-feeding is not recommended while using this drug. Consult your doctor before breast-feeding.

            DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Avoid taking MAO inhibitors (isocarboxazid, linezolid, metaxalone, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before treatment with this medication. Ask your doctor when to start or stop taking this medication.Some products have ingredients that could raise your heart rate or blood pressure. Tell your pharmacist what products you are using, and ask how to use them safely (especially cough-and-cold products or diet aids).The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/ "ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.Dextroamphetamine is very similar to amphetamine or lisdexamfetamine. Do not use medications containing amphetamine or lisdexamfetamine while using dextroamphetamine.This medication may interfere with certain medical/lab tests (such as blood and urine steroid levels, brain scan for Parkinson's disease), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.

            OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center. Symptoms of overdose may include: headache that is severe or doesn't go away, severe mental/mood changes, seizures, severe restlessness, fast breathing.
