Indications

Dosage

  • 8 mg/kg IV infusion over 90 minutes (1st dose)
  • subsequent doses 6 mg/kg, every 3 weeks for 1 year[3]
    • may be given for 9 weeks rather than 1 year[4]
    • no reason to change 1 year duration of therapy[8]
    • 6 months of therapy equivalent to 1 year[19]

Monitor

* no indication for continued surveillance with echocardiography or cardiac magnetic resonance imaging if LV systolic function normal 6 months after completion of therapy, & no signs or symptoms of heart failure[7]

Adverse effects

* cardiotoxicity may be diminished if given before anthracycline

* restrictive cardiomyopathy not confirmed as complication
