Drug-drug:
Renal Impairment
CCr 3050 mL/min: Administer 75% of normal dose; CCr <30 mL/min or hemodialysis: Administer 50% of normal dose.
Hepatic Impairment
Serum bilirubin 1.23 mg/dL: Administer 75% of normal dose; Serum bilirubin >3 mg/dL: Administer 50% of normal dose.
Monitor for bone marrow suppression. Assess for bleeding (bleeding gums; bruising; petechiae; guaiac stools, urine, and emesis) and avoid IM injections and taking rectal temperatures if platelet count is low. Apply pressure to venipuncture sites for 10 min. Assess for signs of infection during neutropenia. Anemia may occur. Monitor for ↑ fatigue, dyspnea, and orthostatic hypotension.
Assess IV site frequently for inflammation or infiltration. Instruct patient to notify nurse immediately if pain or irritation at injection site occurs. If extravasation occurs, infusion must be stopped and restarted in another vein to avoid damage to SUBQ tissue. Notify health care provider immediately. Daunorubicin is a vesicant. If extravasation occurs, stop infusion immediately and disconnect (leave cannula/needle in place); gently aspirate extravasated solution (do NOT flush line); remove needle/cannula; elevate extremity. Initiate antidote (dexrazoxane [adult] or dimethyl sulfate [DMSO]). Apply dry cold compresses for 20 min 4 times daily for 12 days; hold cooling beginning 15 min before dexrazoxane infusion; continue holding cooling until 15 min after infusion is completed. Do not administer topical DMSO in combination with dexrazoxane; may lessen dexrazoxane efficacy.
Assess for evidence of cardiotoxicity, which manifests as HF (peripheral edema, dyspnea, rales/crackles, weight gain, JVD) and usually occurs 16 mo after initiation of therapy. Obtain chest x-ray, echocardiography, ECGs, and radionuclide angiography determination of left ventricular ejection fraction (LVEF) before each course of therapy and periodically during therapy. A 30% ↓ in QRS voltage and ↓ in LVEF are early signs of cardiotoxicity. Patients who receive total cumulative doses >550/mm2, who have a history of cardiac disease, or who have received mediastinal radiation are at ↑ risk of developing cardiotoxicity. Cardiotoxicity may develop if cumulative dose >400550 mg/m2 in adults, 300 mg/m2 in children >2 yr, or 10 mg/kg in children <2 yr. May be irreversible and fatal, but usually responds to early treatment.
Lab Test Considerations:
Monitor CBC and differential before and frequently during therapy. The leukocyte count nadir occurs 1014 days after administration. Recovery usually occurs within 21 days after administration of daunorubicin.
Administer under supervision of a physician experienced in use of cancer chemotherapeutic agents.
IV Administration:
Instruct patient to notify health care provider if fever; chills; sore throat; signs of infection; bleeding gums; bruising; petechiae; or blood in urine, stool, or emesis occurs. Caution patient to avoid crowds and persons with known infections. Instruct patient to use soft toothbrush and electric razor. Patient should be cautioned not to drink alcoholic beverages.
Instruct patient to notify health care provider immediately if irregular heartbeat, shortness of breath, or swelling of lower extremities occurs.
