Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Adderall 15 is a combination of amphetamine and dextroamphetamine, which increase synaptic concentrations of norepinephrine and dopamine by inhibiting their reuptake and promoting their release from presynaptic terminals.
Deferoxamine is an iron-chelating agent that binds ferric iron forming ferrioxamine, a stable complex that is excreted renally, reducing iron accumulation in tissues.
Attention deficit hyperactivity disorder (ADHD),Narcolepsy
Acute iron intoxication,Chronic iron overload due to transfusion-dependent anemias (e.g., thalassemia major),Chronic iron overload due to hereditary hemochromatosis with contraindications to phlebotomy,Chelation therapy in patients with secondary iron overload from myelodysplastic syndromes or sickle cell disease (off-label)
10-20 mg orally once daily in the morning; may increase by 5-10 mg weekly; maximum 40 mg/day.
Acute iron poisoning: 1 g IM, then 0.5 g IM every 4-12 hours; max 6 g/day. Chronic iron overload: 0.5-1 g IM daily; also IV/SC 20-40 mg/kg/day over 8-24 hours.
Mean terminal half-life: d-amphetamine 10 h, l-amphetamine 13 h (range 9-14 h); for ADDERALL 15 (3:1 mix), effective half-life ~11 h; clinical context: dosing interval typically QD-BID.
Terminal elimination half-life: 6-12 hours (prolonged in iron overload, up to 20-30 hours with large doses; clinical context: supports subcutaneous infusion over 8-12 hours for chronic chelation).
Amphetamine is metabolized primarily by hepatic CYP2D6 and to a lesser extent by CYP2C19 and CYP2C9, with some minor pathways involving dopamine beta-hydroxylase.
Deferoxamine is metabolized primarily in the liver via oxidative deamination to two major metabolites: an acid-degradation product and a neutral compound. The exact enzymes are not well-defined but likely involve hepatic oxidases.
Primarily renal (90% as unchanged drug and metabolites; ~30% unchanged, 40% as 4-hydroxyamphetamine and conjugates, 20% as other metabolites); minimal biliary/fecal elimination (<3%).
Renal: approximately 40-60% of absorbed dose excreted in urine as unchanged drug and iron complex; biliary/fecal: minor route, <5%.
~16-20%; primarily binds to albumin, with minor binding to alpha-1-acid glycoprotein.
~10-20% bound to plasma proteins; primarily albumin and transferrin (minimal due to low affinity).
Vd: 3.0-4.5 L/kg (range 2.6-5.6); indicates extensive tissue distribution, including brain, with accumulation in kidneys and liver.
Dry weight: 1.5-2.0 L/kg (indicates extensive distribution into extracellular fluid and tissues; increased in iron overload due to iron stores).
Oral: ~76% (range 64-95%) for mixed amphetamine salts; bioavailability reduced by acidic gastric p H and increased with food (Tmax delayed but AUC unchanged).
Subcutaneous: ~80-90% (injectable only; oral bioavailability negligible, <5%).
GFR 15-29 m L/min: reduce dose by 50%; GFR <15 m L/min: contraindicated.
GFR >60 m L/min: no adjustment; GFR 10-60: reduce dose by 50%; GFR <10: avoid use or use with extreme caution.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 50%; Child-Pugh C: contraindicated.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25-50%; Child-Pugh C: avoid use.
Weight-based: <50 kg: 2.5-5 mg once daily; 50-100 kg: 5-10 mg once daily; >100 kg: adult dosing.
Acute poisoning: 15 mg/kg/h IV initially, max 6 g/24h; acute chronic overload: 20-40 mg/kg/day SC/IV over 8-24h.
Start at 2.5-5 mg once daily; increase slowly due to increased sensitivity and cardiovascular risk.
Start at lower end of dosing range due to potential renal impairment; monitor renal function and iron levels.
WARNING: ABUSE AND DEPENDENCE. CNS stimulants, including Adderall, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence throughout therapy.
None
Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities or other serious heart problems,Blood pressure and heart rate increases,Psychiatric adverse events (exacerbation of pre-existing psychosis, manic episodes, aggressive behavior),Seizures (may lower seizure threshold),Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk, especially with concomitant serotonergic drugs,Long-term growth suppression in children
Hypersensitivity reactions including anaphylaxis, urticaria, and angioedema,Ocular toxicity (cataracts, decreased visual acuity, retinal damage) with high doses or prolonged therapy,Auditory toxicity (tinnitus, sensorineural hearing loss) especially at high doses,Renal impairment may reduce drug clearance; monitor renal function,Growth retardation in children with long-term use,Increased risk of infections, particularly Yersinia enterocolitica and Mucorales fungi,Severe neurotoxicity including seizures, coma, and encephalopathy, especially with rapid intravenous administration,Acute respiratory distress syndrome (ARDS) reported with rapid IV infusion
Hypersensitivity to amphetamine or other components,Concurrent use or within 14 days of MAOIs (risk of hypertensive crisis),Glaucoma,Hyperthyroidism,Agitated states,History of drug abuse,Cardiovascular disease (symptomatic, moderate to severe hypertension, advanced arteriosclerosis, structural cardiac abnormalities)
Severe renal disease or anuria (as drug is excreted renally),Hypersensitivity to deferoxamine or any component of the formulation,Primary hemochromatosis with mild iron overload (prefer phlebotomy)
Avoid high-fat meals close to dosing as they may delay absorption. Acidic foods (e.g., citrus, cola, vitamin C) can decrease absorption; take with non-acidic fluids. Avoid alcohol and caffeine-containing products.
Avoid high-iron foods (e.g., red meat, liver, fortified cereals) during therapy. Do not take with vitamin C supplements as they may increase iron absorption and toxicity. No significant food interaction except iron-containing foods/supplements.
First trimester: Possible increased risk of congenital malformations (cardiac, oral clefts) based on limited human data; animal studies show dose-dependent teratogenicity. Second/third trimesters: Risk of fetal growth restriction, preterm delivery, neonatal withdrawal (irritability, feeding problems), and persistent pulmonary hypertension.
FDA Category C. First trimester: Animal studies show fetal abnormalities, but no adequate human studies. Second/Third trimesters: Avoid unless essential; deferoxamine crosses placenta and may cause fetal skeletal anomalies, anemia, and growth restriction at high doses.
Present in breast milk; M/P ratio approximately 2.5-7.5. Potential for infant stimulation, insomnia, reduced weight gain. Caution recommended; consider delaying breastfeeding until 1-2 hours after dose.
Excreted into breast milk in low levels; M/P ratio unknown. Use with caution, especially in infants with iron overload; consider risk of maternal iron deficiency. Monitor infant for gastrointestinal effects.
Pregnancy reduces amphetamine plasma concentrations by 15-50% during second/third trimesters due to increased clearance. Dose may need upward titration to maintain clinical effect, with careful monitoring for adverse effects.
No standard dose adjustment; lower doses may be required due to increased plasma volume and renal clearance. Monitor iron levels closely; avoid high doses to minimize fetal toxicity.
Adderall 15 mg (amphetamine/dextroamphetamine) is an immediate-release formulation; onset 30-60 min, duration 4-6 hours. Avoid afternoon doses to prevent insomnia. Monitor for hypertension, tachycardia, and growth suppression in children. Consider drug holidays to assess need and reduce tolerance. Do not use with MAOIs or within 14 days of MAOI therapy. Risk of abuse and dependence; screen for substance use history. Use with caution in patients with pre-existing cardiovascular disease or psychiatric disorders.
Administer IM or IV, but avoid rapid IV infusion to prevent hypotension. Monitor urine color for reddish hue indicating iron excretion. For acute iron poisoning, check serum iron and total iron-binding capacity (TIBC); chelation is indicated if serum iron exceeds TIBC or >350 mcg/d L. Use test dose (50 mg/kg) if uncertain of iron overload. Avoid in severe renal failure unless dialysis is available due to desferrioxamine-iron complex excretion. Can cause Yersinia enterocolitica infection; discontinue if fever or diarrhea develops.
