Myocardial Toxicity and Severe Myelosuppression

1.Daunorubicin Hydrochloride Injection must be given into a rapidly flowing intravenous infusion. It must never be given by the intramuscular or subcutaneous route. Severe local tissue necrosis will occur if there is extravasation during administration.

2.Myocardial toxicity manifested in its most severe form by potentially fatal congestive heart failure may occur either during therapy or months to years after termination of therapy. The incidence of myocardial toxicity increases after a total cumulative dose exceeding 400 to 550 mg/m2 in adults, 300 mg/m2 in children more than 2 years of age, or 10 mg/kg in children less than 2 years of age.

3.Severe myelosuppression occurs when used in therapeutic doses; this may lead to infection or hemorrhage.

4.It is recommended that daunorubicin hydrochloride be administered only by physicians who are experienced in leukemia chemotherapy and in facilities with laboratory and supportive resources adequate to monitor drug tolerance and protect and maintain a patient compromised by drug toxicity. The physician and institution must be capable of responding rapidly and completely to severe hemorrhagic conditions and/or overwhelming infection.

5.Dosage should be reduced in patients with impaired hepatic or renal function.
