Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Immunomodulatory drug with antineoplastic activity; targets cereblon, leading to ubiquitination and degradation of transcription factors Ikaros (IKZF1) and Aiolos (IKZF3), resulting in direct cytotoxicity and immune modulation.
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.

WARNING: EMBRYO-FETAL TOXICITY, VENOUS AND ARTERIAL THROMBOEMBOLISM, HEPATOTOXICITY, and INCREASED MORTALITY IN MULTIPLE MYELOMA. Pomalidomide is contraindicated in pregnant women due to teratogenicity. Thromboembolic events (DVT, PE, MI, stroke) are increased. Hepatotoxicity may be severe. In multiple myeloma clinical trials, pomalidomide/dexamethasone was associated with increased mortality in patients with high-risk cytogenetics (del 17p, t(4;14), t(14;16)).
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.
Embryo-fetal toxicity (must use contraception); venous/arterial thromboembolism (consider prophylaxis); hepatotoxicity (monitor LFTs); increased mortality in high-risk multiple myeloma; hematologic toxicity (neutropenia, thrombocytopenia); cardiac toxicity (arrhythmias, heart failure); severe cutaneous reactions; tumor lysis syndrome; renal impairment; fetal risk during pregnancy; avoid use in patients with prior hypersensitivity to thalidomide analogs.
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.
Pregnancy (absolute); women of childbearing potential not using effective contraception; men not using condoms during sexual activity with pregnant or non-pregnant women; hypersensitivity to pomalidomide or thalidomide analogs; prior severe dermatologic reactions to pomalidomide.
Pregnancy (due to teratogenicity),Women of childbearing potential not using effective contraception,Hypersensitivity to lenalidomide or any component of the formulation
Avoid grapefruit juice and grapefruit products. Take with water, not with food to reduce nausea.
Avoid grapefruit and grapefruit juice; they may increase lenalidomide exposure. No other significant food interactions are known.
First trimester: High risk of severe birth defects (e.g., limb anomalies, neural tube defects) due to potent teratogenicity; absolutely contraindicated. Second/third trimester: Risk of fetal harm persists; no safe level established; discontinue if possible.
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.
No data on M/P ratio; excreted in animal milk; potential for serious adverse reactions in infant; breastfeeding contraindicated during therapy and for at least 7 days after last dose.
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.
No specific dose adjustments in pregnancy due to contraindication; pharmacokinetic changes (e.g., increased clearance) theoretically require higher doses if used, but teratogenicity prohibits use; avoid exposure entirely.
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.
Thromboprophylaxis with aspirin or low molecular weight heparin is mandatory due to high VTE risk. Monitor CBC and thyroid function monthly. Contraindicated in pregnancy due to teratogenicity. Pomalidomide requires REMS program enrollment. Dose reduction needed for renal impairment (Cr Cl <45 m L/min).
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).
Do not become pregnant while taking this drug; use two reliable forms of contraception.,Report any signs of bleeding or bruising, as pomalidomide can cause low platelet counts.,Avoid grapefruit and grapefruit juice as they may increase drug levels.,Take capsules whole, not crushed or chewed, with water.,Do not donate blood during treatment and for 4 weeks after stopping.
Do not share this medication with others; it can cause severe birth defects.,Use two forms of contraception or abstain from sex during treatment and for 4 weeks after stopping.,Report any new shortness of breath, chest pain, or leg swelling immediately.,Avoid grapefruit and grapefruit juice while taking this medication.,Do not donate blood during treatment and for 4 weeks after stopping.
"Dextropropoxyphene, an opioid analgesic, and pomalidomide, an immunomodulatory agent, both pose risks of QT interval prolongation. Co-administration may result in additive QT prolongation, increasing the risk of torsade de pointes, a potentially fatal ventricular arrhythmia. Additionally, dextropropoxyphene may exacerbate the sedative and respiratory depressant effects of pomalidomide, leading to excessive central nervous system depression."
"Concomitant use of pomalidomide and perampanel may result in additive central nervous system (CNS) depression due to their independent sedative properties. Pomalidomide, an immunomodulatory drug, is associated with somnolence and fatigue, while perampanel, an AMPA receptor antagonist, commonly causes dizziness, somnolence, and ataxia. This combination can lead to excessive sedation, impaired cognitive function, and increased risk of falls or accidents, particularly in elderly patients or those with impaired hepatic function."
"The concurrent use of desflurane, a halogenated inhalational anesthetic, with pomalidomide, an immunomodulatory agent, may potentiate the risk of severe hypotension and bradycardia due to additive cardiovascular depression. Desflurane directly depresses myocardial contractility and systemic vascular resistance, while pomalidomide can induce vasodilation and negative chronotropic effects. Clinically, patients may experience profound drops in blood pressure and heart rate, leading to reduced cardiac output and potential end-organ hypoperfusion."
