REVLIMID vs ADDERALL 20
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Revlimid (lenalidomide) is an immunomodulatory agent with antiangiogenic and antineoplastic properties. It inhibits tumor necrosis factor-alpha, stimulates T-cell proliferation and IL-2 production, and inhibits angiogenesis by blocking VEGF and b FGF. It also modulates the ubiquitin E3 ligase cereblon, leading to degradation of transcription factors Ikaros and Aiolos, which results in direct tumor cell apoptosis and enhanced immune function.
Adderall 20 is a combination of amphetamine and dextroamphetamine, which are central nervous system stimulants. They increase the levels of norepinephrine and dopamine in synaptic clefts by inhibiting their reuptake and promoting their release from presynaptic neurons.

5-10 mg orally once daily for 21 days of a 28-day cycle; dose depends on indication (e.g., 10 mg for transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes).
Initial: 5 mg orally once or twice daily; may increase by 5 mg increments at weekly intervals. Usual effective dose: 20-40 mg/day divided into 1-2 doses. Maximum: 40 mg/day (immediate-release); 60 mg/day (extended-release).
Terminal elimination half-life of approximately 3-5 hours in patients with normal renal function. Half-life is prolonged in renal impairment (up to 9 hours in severe impairment).
d-Amphetamine: 10-13h; l-Amphetamine: 13-16h. Clinical steady-state reached in 2-3 days.
Lenalidomide is primarily metabolized via hydrolysis, with minor involvement of CYP1A2 and CYP3A4. The major route of elimination is renal excretion of unchanged drug; approximately 67% of the dose is excreted unchanged in urine.
Primarily hepatic via CYP2D6 and, to a lesser extent, CYP2C19, CYP3A4, and CYP2C9. Metabolites include 4-hydroxyamphetamine, alpha-hydroxyamphetamine, and norephedrine.
Primarily renal excretion as unchanged drug (approximately 67% of the dose in urine over 24 hours) with minor fecal elimination (<4%).
Renal: ~90% unchanged; ~10% as deaminated metabolites; fecal <5%.
Approximately 30% bound to plasma proteins, primarily albumin.
16% (primarily albumin).
Volume of distribution (Vd) is approximately 0.6-1.0 L/kg, indicating distribution into total body water and some tissue binding.
3.2-5.6 L/kg; indicates extensive tissue distribution.
Absolute oral bioavailability is approximately 33% (range 20-50%) due to first-pass metabolism. Food does not significantly alter bioavailability.
Oral IR: ~90%; ER: ~90%.
For Cr Cl ≥60 m L/min: start at 10 mg daily; Cr Cl 30-60 m L/min: start at 5 mg daily; Cr Cl <30 m L/min: 5 mg every other day; for dialysis patients: 5 mg three times weekly after dialysis.
e GFR 15-29 m L/min: 50% of usual dose. e GFR < 15 m L/min: avoid use due to accumulation risk. Hemodialysis: not recommended.
No specific Child-Pugh based dose adjustments provided in labeling; use caution and monitor for toxicity in hepatic impairment.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 50%. Child-Pugh Class C: avoid use.
Safety and efficacy not established; not recommended for pediatric use outside clinical trials.
Children 3-5 years: 2.5 mg orally once daily; increase by 2.5 mg weekly. Children 6 years and older: 5 mg once or twice daily; increase by 5 mg weekly. Maximum dose: 40 mg/day (immediate-release). Weight-based: 0.3-1.5 mg/kg/day (immediate-release).
No specific dose adjustment based solely on age; monitor renal function and adjust per renal guidelines as elderly often have decreased Cr Cl.
Initial: 2.5 mg once or twice daily; increase slowly by 2.5 mg increments at weekly intervals. Use lowest effective dose due to increased sensitivity and risk of cardiovascular adverse effects.
Revlimid (lenalidomide) can cause fetal harm. Women of childbearing potential must use effective contraception and undergo pregnancy testing prior to and during therapy. There is an increased risk of venous thromboembolism, including deep vein thrombosis and pulmonary embolism. The drug is contraindicated in pregnant women.
Abuse and dependence: Amphetamines have a high potential for abuse, which can lead to dependence and serious cardiovascular events. Misuse may cause sudden death or serious cardiovascular adverse events.
Hematologic toxicity: Neutropenia and thrombocytopenia are common, requiring dose adjustments.,Thromboembolism: Increased risk of DVT, PE, and stroke; consider prophylactic anticoagulation or antiplatelet therapy.,Second primary malignancies: Risk of development of other cancers (e.g., AML, MDS) in patients receiving lenalidomide.,Hepatotoxicity: Elevations of liver enzymes have been reported.,Allergic reactions: Including angioedema and Stevens-Johnson syndrome.,Renal impairment: Requires dose adjustment; monitor renal function.
Cardiovascular: Serious cardiovascular events including sudden death in patients with pre-existing structural cardiac abnormalities.,Psychiatric: Exacerbation of pre-existing psychosis, mania, or aggression; new-onset psychosis or mania.,Growth suppression: Long-term use in children may suppress growth.,Seizures: May lower seizure threshold in patients with seizure disorders.,Serotonin syndrome: Risk when used with other serotonergic drugs.,Peripheral vasculopathy: Including Raynaud's phenomenon.
Pregnancy (due to teratogenicity),Women of childbearing potential not using effective contraception,Hypersensitivity to lenalidomide or any component of the formulation
Hypersensitivity to amphetamine or any component of the formulation,Advanced arteriosclerosis,Symptomatic cardiovascular disease,Moderate to severe hypertension,Hyperthyroidism,Glaucoma,Agitated states,History of drug abuse,Concurrent use or within 14 days of MAO inhibitors (risk of hypertensive crisis)
Avoid grapefruit and grapefruit juice; they may increase lenalidomide exposure. No other significant food interactions are known.
High-fat meals can delay absorption of Adderall. Acidic foods (e.g., citrus fruits, juices) and vitamin C may decrease absorption; avoid within 1 hour of dosing. Caffeine and other stimulants may increase side effects. Alcohol should be avoided. Grapefruit juice may increase amphetamine levels, so limit or avoid.
REVLIMID (lenalidomide) is an analog of thalidomide, a known human teratogen. It is absolutely contraindicated in pregnancy. Fetal exposure can cause severe, life-threatening birth defects including limb reduction, cardiac anomalies, and neural tube defects. Risk is highest during the first trimester but extends throughout gestation.
First trimester: Increased risk of premature delivery and low birth weight; possible association with cardiovascular malformations (limited data). Second/third trimester: Risk of fetal growth restriction, preterm birth, neonatal withdrawal syndrome (irritability, poor feeding), and persistent pulmonary hypertension. Chronic use may impair fetal development.
It is unknown if lenalidomide is excreted in human breast milk. Due to the potential for serious adverse reactions in nursing infants, breastfeeding is contraindicated. M/P ratio is not available.
Excreted into breast milk; M/P ratio approximately 2.5–7.5. Relative infant dose estimated at 5–14% of maternal weight-adjusted dose. Potential for decreased appetite, insomnia, and growth suppression in breastfed infants. American Academy of Pediatrics recommends use only if benefit outweighs risk, with close monitoring.
There are no dose adjustments for pregnancy because the drug is contraindicated; it must be discontinued immediately if pregnancy occurs. No pharmacokinetic studies in pregnancy are available.
Due to increased renal clearance and expanded plasma volume, total amphetamine exposure may decrease, potentially requiring dose increase (monitor clinical response). However, insufficient data to recommend fixed adjustments; individualize based on symptom control and tolerability.
Monitor for thromboembolic events; use with aspirin or anticoagulant prophylaxis. Perform pregnancy tests weekly during first month, then monthly in women of childbearing potential. Dose reduce for Cr Cl <60 m L/min. Avoid in severe hepatic impairment (Child-Pugh C).
Adderall 20 mg is a mixed amphetamine salt formulation (75% dextroamphetamine, 25% levoamphetamine). Monitor for cardiovascular adverse effects; consider baseline ECG in patients with cardiac risk factors. Avoid in patients with structural cardiac abnormalities, cardiomyopathy, or arrhythmias. Use with caution in patients with hypertension, hyperthyroidism, or glaucoma. May exacerbate tics and Tourette syndrome. Administer first dose upon awakening; avoid afternoon doses due to insomnia risk. Monitor growth in children; may cause weight loss and growth suppression. Assess for potential for abuse and dependence; use lowest effective dose.
