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 12.5 is a combination of dextroamphetamine and amphetamine. It increases the levels of dopamine and norepinephrine in the central nervous system by inhibiting their reuptake and promoting their release from presynaptic neurons.
Multiple myeloma (in combination with dexamethasone),Myelodysplastic syndromes (MDS) associated with deletion 5q abnormality,Mantle cell lymphoma,Follicular lymphoma (in combination with rituximab)
Attention deficit hyperactivity disorder (ADHD),Narcolepsy (off-label)
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).
5-60 mg orally once or twice daily; immediate-release: initial 5 mg once or twice daily, increase by 5 mg weekly; extended-release: initial 20 mg once daily in the morning, increase by 10 mg weekly.
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).
The terminal elimination half-life of d-amphetamine is approximately 10–13 hours in adults (range 9–14 h) and 6–8 hours in children. Clinical context: Typically allows twice-daily dosing; extended-release formulations provide 8–12 hours of effect.
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.
Amphetamine and dextroamphetamine are extensively metabolized in the liver via CYP2D6 and other pathways. The primary metabolites are 4-hydroxyamphetamine and 4-hydroxynorephedrine.
Primarily renal excretion as unchanged drug (approximately 67% of the dose in urine over 24 hours) with minor fecal elimination (<4%).
Approximately 30% of the dose is excreted unchanged in urine; the remainder is metabolized primarily via deamination and oxidation. Renal elimination of unchanged amphetamine is p H-dependent: acidic urine increases elimination, alkaline urine decreases it. Fecal excretion accounts for <5%.
Approximately 30% bound to plasma proteins, primarily albumin.
Approximately 15–20% bound to plasma proteins, primarily albumin.
Volume of distribution (Vd) is approximately 0.6-1.0 L/kg, indicating distribution into total body water and some tissue binding.
Mean volume of distribution is 3.5–4.6 L/kg, indicating extensive tissue distribution. Clinical meaning: Large Vd reflects sequestration in tissues (including brain), contributing to prolonged presence.
Absolute oral bioavailability is approximately 33% (range 20-50%) due to first-pass metabolism. Food does not significantly alter bioavailability.
Oral bioavailability is highly variable, ranging from 75–100% for immediate-release tablets; food does not significantly affect overall absorption but may delay time to peak concentration. Extended-release capsules have bioavailability approximately 96% relative to immediate-release.
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.
GFR 15-29 m L/min: reduce dose to 50% of usual; GFR <15 m L/min: use 50% of usual dose; hemodialysis: not removed, avoid use.
No specific Child-Pugh based dose adjustments provided in labeling; use caution and monitor for toxicity in hepatic impairment.
Child-Pugh A: no adjustment; Child-Pugh B: use 50% of usual dose; Child-Pugh C: avoid use.
Safety and efficacy not established; not recommended for pediatric use outside clinical trials.
Immediate-release: 3-5 years: initial 2.5 mg once daily, increase by 2.5 mg weekly up to 40 mg/day; 6+ years: initial 5 mg once or twice daily, increase by 5 mg weekly up to 40 mg/day. Extended-release: 6-12 years: initial 10 mg once daily, increase by 10 mg weekly up to 30 mg/day; 13-17 years: initial 10 mg once daily, increase by 10 mg weekly up to 40 mg/day.
No specific dose adjustment based solely on age; monitor renal function and adjust per renal guidelines as elderly often have decreased Cr Cl.
Start at lowest dose (5 mg immediate-release or 10 mg extended-release) and titrate slowly due to increased risk of adverse cardiovascular and CNS effects; monitor for hypertension, tachycardia, and agitation.
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.
Adderall has a high potential for abuse and dependence. Prolonged use may lead to drug dependence. 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.
Risk of abuse and dependence,Serious cardiovascular events including sudden death, stroke, and myocardial infarction,Blood pressure and heart rate increases,Psychiatric adverse events including exacerbation of pre-existing psychosis, mania, or aggression,Seizures in patients with seizure disorders,Visual disturbances,Growth suppression in children,Peripheral vasculopathy including Raynaud's phenomenon,Serotonin syndrome risk when used with serotonergic drugs
Pregnancy (due to teratogenicity),Women of childbearing potential not using effective contraception,Hypersensitivity to lenalidomide or any component of the formulation

Avoid grapefruit and grapefruit juice; they may increase lenalidomide exposure. No other significant food interactions are known.
Avoid acidic foods and beverages (e.g., citrus fruits, soda) within 1 hour of administration as they may decrease absorption. High-fat meals may delay absorption of extended-release formulations. Avoid caffeine and other stimulants. Grapefruit juice may increase amphetamine levels.
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 congenital malformations, particularly cardiovascular defects (e.g., septal defects) and oral clefts based on amphetamine exposure. Second and third trimesters: risk of preterm delivery, low birth weight, and neonatal withdrawal syndrome (irritability, feeding difficulties, respiratory distress). Premature delivery and growth restriction have been reported.
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.
Contraindicated due to potential for infant toxicity. M/P ratio not established; amphetamine is excreted into breast milk in small amounts but may accumulate in breastfeeding infants. Adverse effects include irritability, poor feeding, and decreased weight gain.
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.
Pharmacokinetics altered: increased hepatic metabolism and renal clearance in pregnancy may reduce amphetamine exposure; however, safety data do not support dose adjustment. Use lowest effective dose only if necessary; consider alternative non-amphetamine therapies.
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).
