DEXEDRINE vs REVLIMID
Clinician-reviewed, head-to-head comparison of mechanism, dosing, pharmacokinetics, and safety profiles.
Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Dextroamphetamine is a central nervous system stimulant that enhances the activity of dopamine and norepinephrine in the brain by blocking their reuptake and increasing their release from presynaptic terminals.
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.

5–60 mg/day orally in divided doses, typically 5–20 mg 1–3 times daily; use immediate-release or extended-release formulations per indication.
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).
Terminal elimination half-life is 4-6 hours for dextroamphetamine; clinical effects last longer due to CNS accumulation
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).
Primarily metabolized by CYP2D6 to 4-hydroxydextroamphetamine, which is further metabolized to various metabolites. Also undergoes deamination and oxidation.
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.
Renal: 30-45% unchanged, 50-60% as deaminated metabolites; fecal: minor (<5%)
Primarily renal excretion as unchanged drug (approximately 67% of the dose in urine over 24 hours) with minor fecal elimination (<4%).
Approximately 16-20% bound; primarily to albumin
Approximately 30% bound to plasma proteins, primarily albumin.
3.5-4.5 L/kg; indicates extensive tissue distribution, particularly CNS
Volume of distribution (Vd) is approximately 0.6-1.0 L/kg, indicating distribution into total body water and some tissue binding.
Oral: 75-100% (immediate-release), 70-90% (extended-release); rectal and parenteral routes are not clinically utilized
Absolute oral bioavailability is approximately 33% (range 20-50%) due to first-pass metabolism. Food does not significantly alter bioavailability.
GFR 15–30 m L/min: use with caution, consider dose reduction by 50%. GFR <15 m L/min: not recommended.
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.
Child-Pugh A: no adjustment. Child-Pugh B: reduce dose by 50%. Child-Pugh C: not recommended.
No specific Child-Pugh based dose adjustments provided in labeling; use caution and monitor for toxicity in hepatic impairment.
Age 3–5 years: 2.5 mg orally once daily, increase by 2.5 mg weekly as needed (max 40 mg/day). Age ≥6 years: 5 mg orally once or twice daily, increase by 5 mg weekly (max 40 mg/day).
Safety and efficacy not established; not recommended for pediatric use outside clinical trials.
Start at lowest dose (2.5–5 mg orally once daily), titrate slowly; monitor for cardiovascular effects, agitation, and weight loss.
No specific dose adjustment based solely on age; monitor renal function and adjust per renal guidelines as elderly often have decreased Cr Cl.
WARNING: ABUSE AND DEPENDENCE. CNS stimulants, including DEXEDRINE, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing and monitor for signs of abuse and dependence while on therapy.
Revlimid (lenalidomide) can cause fetal harm. Women of childbearing potential must use effective contraception and undergo pregnancy testing prior to and during therapy.

Pregnancy (due to teratogenicity),Women of childbearing potential not using effective contraception,Hypersensitivity to lenalidomide or any component of the formulation
Avoid high-fat meals with immediate-release formulations as they may delay absorption; for extended-release, high-fat meals can increase peak concentration. Acidic foods (e.g., citrus fruits, fruit juices, carbonated drinks) can reduce absorption. Avoid excessive caffeine (coffee, tea, energy drinks) as it may exacerbate central nervous system stimulation and cardiovascular effects. Maintain adequate hydration. Grapefruit and other CYP2D6 inhibitors may increase effects.
Avoid grapefruit and grapefruit juice; they may increase lenalidomide exposure. No other significant food interactions are known.
First trimester: Limited human data; animal studies show increased risk of cardiovascular malformations and cleft palate at high doses. Second/third trimester: Increased risk of preterm delivery, low birth weight, and neonatal withdrawal symptoms (hyperactivity, irritability, feeding difficulties). Dextroamphetamine is a sympathomimetic amine with potential for vasoconstriction reducing uteroplacental perfusion.
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.
Dextroamphetamine is excreted into breast milk; M/P ratio not established but concentration about 2-7 times maternal plasma. potential for infant stimulation, insomnia, and growth impairment. American Academy of Pediatrics recommends use during breastfeeding only if benefits outweigh risks; monitor infant for agitation and poor weight gain.
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.
Pharmacokinetic changes in pregnancy: Increased volume of distribution and enhanced renal clearance may reduce serum concentrations of dextroamphetamine. Dose adjustment may be necessary based on clinical response; start with lowest effective dose and monitor for worsening ADHD symptoms. Avoid in severe hypertension or preeclampsia.
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.
Monitor for hypertension, tachycardia, and mental status changes (psychosis, mania) especially at high doses. Avoid late-day dosing to prevent insomnia. Use with caution in patients with pre-existing cardiovascular disease or hyperthyroidism. Dextroamphetamine can suppress appetite and cause weight loss; monitor growth in children. Abuse potential is high; schedule II controlled substance. Can precipitate tics in susceptible individuals. Contraindicated within 14 days of MAOIs due to hypertensive crisis.
