No specific dose adjustment; consider increased susceptibility to myelosuppression and cardiotoxicity; monitor left ventricular ejection fraction.
No specific dose adjustment recommended, but monitor for increased toxicity (e.g., cardiotoxicity, myelosuppression) due to age-related organ function decline.
Myocardial toxicity, including potentially fatal congestive heart failure, especially with cumulative doses >900 mg/m²; secondary acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS); extravasation leading to severe tissue necrosis; severe myelosuppression.
Cardiotoxicity: risk of myocardial damage, including acute left ventricular failure. Myelosuppression: severe, dose-limiting. Hepatic impairment: requires dose reduction. Infusion reactions: may be severe or life-threatening. Must be administered by physician experienced in cancer chemotherapy.
Cardiotoxicity (cumulative dose-dependent), myelosuppression, secondary leukemia, extravasation, hepatotoxicity, renal impairment, immunosuppression, tumor lysis syndrome, and fetal harm.
Cardiotoxicity (cumulative dose-dependent, monitor LVEF), myelosuppression (neutropenia, thrombocytopenia), infusion reactions (premedicate), hand-foot syndrome (palmar-plantar erythrodysesthesia), secondary malignancies, extravasation necrosis, hepatic impairment (dose adjustment), immunosuppression, embryo-fetal toxicity.

Absolute: history of hypersensitivity to doxorubicin or other anthracyclines. Relative: severe hepatic impairment, severe myelosuppression, pre-existing cardiomyopathy, prior treatment with maximum cumulative doses of anthracyclines (e.g., doxorubicin >550 mg/m², liposomal doxorubicin >900 mg/m²).
Avoid grapefruit and grapefruit juice during treatment as they may affect drug metabolism. No other specific food interactions known.
No specific food interactions reported. Avoid grapefruit juice per general chemotherapy precautions. Maintain adequate oral hygiene; avoid spicy or acidic foods during mucositis.
Pregnancy Category D. First trimester: High risk of teratogenicity including cardiac anomalies, skeletal defects, and fetal demise. Second and third trimesters: Risk of fetal growth restriction, preterm birth, and neonatal myelosuppression. Avoid use unless absolutely necessary.
Doxorubicin hydrochloride liposome injection (DOXIL) is classified as Pregnancy Category D. There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans. Potential benefits may warrant use of the drug in pregnant women despite potential risks. First trimester: High risk of teratogenicity including major malformations (e.g., cardiovascular, neural tube defects). Second and third trimesters: Risk of fetal growth restriction, oligohydramnios, and neonatal myelosuppression. Use only if clearly needed and no safer alternative.
Contraindicated due to potential transfer into breast milk (M/P ratio not available). Theoretical risk of severe adverse effects in infants including bone marrow suppression and cardiotoxicity. Discontinue nursing or drug.
Doxorubicin is excreted in human milk. The milk-to-plasma (M/P) ratio for doxorubicin is approximately 0.5 to 2.0 based on limited data. Because of the potential for serious adverse reactions in nursing infants from doxorubicin (e.g., myelosuppression, cardiotoxicity), discontinue breastfeeding during and for at least 3 months after the last dose of DOXIL.
No established dose adjustments; avoid use if possible. Pharmacokinetic changes include increased volume of distribution and clearance, but insufficient data to recommend dose modification. Use reduced doses if unavoidable, guided by toxicity monitoring.
Pharmacokinetic data in pregnancy are limited; however, physiological changes (e.g., increased plasma volume, hepatic clearance) may alter doxorubicin exposure. No specific dose adjustment guidelines exist. Use the standard dose based on body surface area (BSA) while closely monitoring for toxicity. Consider dose reduction if severe myelosuppression or hepatic impairment occurs. Avoid use in the first trimester if possible.
Ellence (epirubicin) is an anthracycline chemotherapeutic agent. It is a vesicant; extravasation can cause severe tissue necrosis. Administer via a freely flowing IV line. Premedicate with antiemetics. Monitor for cardiotoxicity, which is dose-dependent and may be cumulative. Total lifetime dose should not exceed 900-1000 mg/m². Assess cardiac function (LVEF) before and during treatment. Urine may turn red for 1-2 days after administration. Avoid live vaccines.
Monitor for infusion reactions; premedicate with dexamethasone and antihistamines. Palmar-plantar erythrodysesthesia (hand-foot syndrome) may require dose delay/reduction. Cumulative dose >550 mg/m² increases cardiotoxicity risk. Do not substitute with non-liposomal doxorubicin.
Ellence can cause severe nausea and vomiting; take antiemetics as prescribed.,Report any pain, redness, or swelling at the injection site immediately.,Urine may appear red for 1-2 days after treatment; this is normal.,Use effective contraception during and for at least 6 months after treatment.,Avoid live vaccines (e.g., MMR, varicella) while on this medication.,Report signs of infection (fever, chills), unusual bleeding or bruising, shortness of breath, or chest pain.,Do not breastfeed while taking Ellence.
Report immediately any redness, swelling, or pain on palms or soles (hand-foot syndrome).,Avoid prolonged sun exposure and use sunscreen to prevent photosensitivity.,Notify your doctor if you experience chest pain, shortness of breath, or swelling (cardiotoxicity signs).,Take anti-nausea medications as prescribed; maintain adequate hydration.,Use effective contraception during treatment and for 6 months after.
