Dosing in kidney impairment
Dosage in Patients with Renal Impairment In adult patients with severe renal impairment (GFR 15 to <30 mL/min/1.73 m 2 ), the recommended dose is 15 mg once daily in the morning. In pediatric patients (6 to 17 years of age) with severe renal impairment, the recommended dose is 5 mg once daily. The maximum dose for children 6 to 12 years of age with severe renal impairment is 20 mg once daily.
ADDERALL XR is not recommended in patients with end stage renal disease (ESRD) (GFR <15 mL/min/1.73 m 2 ) [see Use in Specific Populations, Clinical Pharmacology] .
Preparation and administration
General Administration Information Individualize the dosage according to the therapeutic needs and response of the patient. Administer ADDERALL XR at the lowest effective dosage. Based on bioequivalence data, patients taking divided doses of immediate-release ADDERALL, (for example, twice daily), may be switched to ADDERALL XR at the same total daily dose taken once daily.
Titrate at weekly intervals to appropriate efficacy and tolerability as indicated. ADDERALL XR extended-release capsules may be taken whole, or the capsule may be opened and the entire contents sprinkled on applesauce. If the patient is using the sprinkle administration method, the sprinkled applesauce should be consumed immediately; it should not be stored.
Patients should take the applesauce with sprinkled beads in its entirety without chewing. The dose of a single capsule should not be divided. The contents of the entire capsule should be taken, and patients should not take anything less than one capsule per day. ADDERALL XR may be taken orally with or without food. ADDERALL XR should be given upon awakening.
Afternoon doses should be avoided because of the potential for insomnia.
Drug interactions
Check dextroamphetamine and amphetamine extended-release against a medication listLabel text (6 paragraphs)
Alkalinizing agents (GI antacids and urinary): These agents increase blood levels of amphetamine. ( 2.7 , 7.1 ) Acidifying agents (GI and urinary): These agents reduce blood levels of amphetamine. ( 7.1 )
7.1 Clinically Important Interactions with Amphetamines Table 4: Drugs Having Clinically Important Interactions with Amphetamines Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact Concomitant use of MAOIs and CNS stimulants can cause hypertensive crisis. Potential outcomes include death, stroke, myocardial infarction, aortic dissection, ophthalmological complications, eclampsia, pulmonary edema, and renal failure. Intervention Do not administer ADDERALL XR concomitantly or within 14 days after discontinuing MAOI [see Contraindications ( 4 )] . Serotonergic Drugs Clinical Impact The concomitant use of ADDERALL XR and serotonergic drugs increases the risk of serotonin syndrome.
Intervention Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome, particularly during ADDERALL XR initiation or dosage increase. If serotonin syndrome occurs, discontinue ADDERALL XR and the concomitant serotonergic drug(s) [see Warnings and Precautions ( 5.8 )] . CYP2D6 Inhibitors Clinical Impact The concomitant use of ADDERALL XR and CYP2D6 inhibitors may increase the exposure of ADDERALL XR compared to the use of the drug alone and increase the risk of serotonin syndrome. Intervention Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome particularly during ADDERALL XR initiation and after a dosage increase.
If serotonin syndrome occurs, discontinue ADDERALL XR and the CYP2D6 inhibitor [see Warnings and Precautions ( 5.8 ), Overdosage ( 10 )] . Alkalinizing Agents Clinical Impact Increase blood levels and potentiate the action of amphetamine. Intervention Coadministration of ADDERALL XR and gastrointestinal or urinary alkalinizing agents should be avoided. Acidifying Agents Clinical Impact Lower blood levels and efficacy of amphetamines. Intervention Increase dose based on clinical response.
Tricyclic Antidepressants Clinical Impact May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d-amphetamine in the brain; cardiovascular effects can be potentiated. Intervention Monitor frequently and adjust or use alternative therapy based on clinical response. Proton Pump Inhibitors Clinical Impact Time to maximum concentration (T max ) of amphetamine is decreased compared to when administered alone. Intervention Monitor patients for changes in clinical effect and adjust therapy based on clinical response.
7.2 Interference with Laboratory Tests Amphetamines can cause a significant elevation in plasma corticosteroid levels. This increase is greatest in the evening. Amphetamines may interfere with urinary steroid determinations. Allow for an adequate washout period between administration of ADDERALL XR and radioactive diagnostic agents used for dopamine transporter (DAT) visualization. ADDERALL XR can interfere with the test results of a radioactive diagnostic agent (ioflupane I-123) that is used for DAT visualization by binding and internalization of the DAT, which may result in lower DAT in the striatum. This may lead to false-positive diagnostic results.
Contraindications
4 CONTRAINDICATIONS ADDERALL XR administration is contraindicated in patients: known to be hypersensitive to amphetamine, or other components of ADDERALL XR. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other amphetamine products [see Adverse Reactions ( 6.2 )] . taking monoamine oxidase inhibitors (MAOIs), or within 14 days of stopping MAOIs (including MAOIs such as linezolid or intravenous methylene blue), because of an increased risk of hypertensive crisis [see Warnings and Precautions ( 5.8 ), Drug Interactions ( 7.1 )]. Known hypersensitivity or idiosyncrasy to amphetamine.
( 4 ) During or within 14 days following the administration of monoamine oxidase inhibitors (MAOI). ( 4 , 7.1 )

Pregnancy and lactation
Pregnancy
8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADDERALL XR during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/othermedications/ . Risk Summary Available data from published epidemiologic studies and postmarketing reports on use of prescription amphetamine in pregnant women have not identified a drug-associated risk of major birth defects and miscarriage (see Data ) .
Adverse pregnancy outcomes, including premature delivery and low birth weight, have been seen in infants born to mothers taking amphetamines during pregnancy (see Clinical Considerations ) . No apparent effects on morphological development were observed in embryo-fetal development studies, with oral administration of amphetamine to rats and rabbits during organogenesis at doses 2 and 12 times, respectively, the maximum recommended human dose (MRHD) of 20 mg/day given to adolescents, on a mg/m 2 basis.
However, in a pre- and postnatal development study, amphetamine (d- to l- ratio of 3:1) administered orally to pregnant rats during gestation and lactation caused a decrease in pup survival and a decrease in pup body weight that correlated with a delay in developmental landmarks at clinically relevant doses of amphetamine. In addition, adverse effects on reproductive performance were observed in pups whose mothers were treated with amphetamine. Long-term neurochemical and behavioral effects have also been reported in animal developmental studies using clinically relevant doses of amphetamine (see Data ) .
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Amphetamines, such as ADDERALL XR, cause vasoconstriction and thereby may decrease placental perfusion. In addition, amphetamines can stimulate uterine contractions, increasing the risk of premature delivery.
Infants born to mothers taking amphetamines during pregnancy have an increased risk of premature delivery and low birth weight. Monitor infants born to mothers taking…
