Boxed warning. CARDIAC TOXICITY, SECONDARY MALIGNANCIES, EXTRAVASATION AND TISSUE NECROSIS, and SEVERE MYELOSUPPRESSION - Cardiac Toxicity: Myocardial damage, including acute left ventricular failure, can occur with Epirubicin. The risk of cardiomyopathy is proportional to the cumulative exposure with incidence rates from 0.9% at a cumulative dose of 550 mg/m 2, 1.6% at 700 mg/m 2, and 3.3% at 900 mg/m 2. The risk of cardiomyopathy is further increased with concomitant cardiotoxic therapy. Assess left ventricular ejection fraction (LVEF) before and regularly during and after treatment with Epirubicin. - Secondary Malignancies: Secondary acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS) occur at a higher incidence in patients treated with anthracyclines, including Epirubicin. - Extravasation and Tissue Necrosis: Extravasation of Epirubicin can result in severe local tissue injury and necrosis requiring wide excision of the affected area and skin grafting. Immediately terminate the drug and apply ice to the affected area. - Severe myelosuppression resulting in serious infection, septic shock, requirement for transfusions, hospitalization, and death may occur. WARNING: CARDIAC TOXICITY, SECONDARY MALIGNANCIES, EXTRAVASATION AND TISSUE NECROSIS, and SEVERE MYELOSUPPRESSION See full prescribing information for complete boxed warning. - Cardiac Toxicity: Myocardial damage, including acute left ventricular failure, can occur with Epirubicin. - Use in Patients with Hepatic Impairment: Monitor serum total bilirubin and AST levels before and during treatment with Epirubicin. In patients with elevated serum AST or serum total bilirubin, dosage reductions or discontinuation may be required. - Tumor Lysis Syndrome: Evaluate blood uric acid levels, potassium, calcium, phosphate, and creatinine after initial treatment. Consider hydration, urine alkalinization, and prophylaxis with allopurinol to minimize potential complications of hyperuricemia and tumor lysis syndrome. - Thrombophlebitis and Thromboembolic Events: Thrombophlebitis and thromboembolic events, including pulmonary embolism (in some cases fatal) have been reported with the use of Epirubicin. Venous sclerosis may result from an injection into a small vessel or from repeated injections into the same vein. - Administration of live or live-attenuated vaccines in patients immunocompromised by chemotherapeutic agents including Epirubicin, may result in serious or fatal infections. - Potentiation of Radiation Toxicity and Radiation Recall: Administration of Epirubicin after previous radiation therapy may induce an inflammatory recall reaction at the site of the irradiation. - Embryo-Fetal Toxicity: Epirubicin can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. Abridged from the full prescribing information.

The following clinically significant adverse reactions are described elsewhere in the labeling: - Cardiac Toxicity - Secondary Malignancies - Extravasation and Tissue Necrosis - Severe Myelosuppression - Tumor-Lysis Syndrome - Thrombophlebitis and Thromboembolic Events - Potentiation of Radiation Toxicity and Radiation Recall The most common adverse reactions (≥10%) are leukopenia, neutropenia, anemia, thrombocytopenia, amenorrhea, lethargy, nausea/vomiting, mucositis, diarrhea, infection, conjunctivitis/keratitis, alopecia, local skin toxicity, and rash/itch.. Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of Epirubicin was evaluated in two studies (Studies MA-5 and GFEA-05) evaluating combination regimens in patients with early breast cancer. Of the 1260 patients treated in these studies, 620 patients received the higher-dose Epirubicin regimen (FEC-100/CEF-120), 280 patients received the lower-dose Epirubicin regimen (FEC-50), and 360 patients received CMF. Serotonin-specific antiemetic therapy and colony-stimulating factors were not used in these trials. Clinically relevant adverse reactions are summarized in Table 1. Table 1. Adverse Reactions in Patients with Early Breast Cancer Event % of Patients FEC-100/CEF-120 (N=620) FEC-50 (N=280) CMF (N=360) Grades 1–4 Grades 3/4 Grades 1–4 Grades 3/4 Grades 1–4 Grades 3/4 FEC & CEF = cyclophosphamide + Epirubicin + fluorouracil; CMF = cyclophosphamide + methotrexate + fluorouracil; NA = not available Grade 1 or 2 changes in transaminase levels were observed but were more frequently seen with CMF than with CEF.
