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)).
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.
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.
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
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.
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)
Avoid grapefruit juice and grapefruit products. Take with water, not with food to reduce nausea.
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.
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.
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.
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.
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.
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.
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.
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).
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.

"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."
