Available forms:
Solution for inj 420 mg/14 ml
•
Visually inspect for particulate matter and discoloration
•
Withdraw the calculated dose from the vial and add to 250 ml 0.9% sodium chloride to PVC or non-PVC polyolefin infusion bag; do not dilute with dextrose 5% solution
•
Dilute in normal saline only; do not mix or dilute with other drugs or dextrose solutions
•
Mix the diluted solution by gentle inversion; do not shake
•
Administer the diluted solution immediately
•
Do not administer as an IV push or bolus
•
Give the first dose of 840 mg over 60 min and subsequent 420 mg doses over 30–60 min
•
If the diluted solution is not used immediately, store at 2°-8° C for up to 24 hr

If time since previous dose is <6 wk, give 420 mg IV (do not wait for next scheduled dose)
•
If time since previous dose is ≥6 wk, give 840 mg IV over 60 min, followed 3 wk later by 420 mg IV over 30–60 min repeated every 3 wk

Can occur and is increased in those with a history of prior anthracycline use or radiotherapy to the chest; evaluate LVEF at baseline and every 3 mo; withhold therapy ×3 wk if LVEF is <40% or LVEF is 40%-45% with a 10% or greater absolute decrease from baseline; resume therapy if the LVEF is recovered to >45% or to 40%-45% with <10% absolute decrease at reassessment; if the LVEF has not improved or has declined further, consider permanently discontinuing pertuzumab and trastuzumab after a risk/benefit assessment
Assess anaphylactoid reaction, acute infusion reaction, cytokine-release syndrome 60 min after the first infusion, 30 min after other infusions; monitor for pyrexia, chills, fatigue, headache, asthenia, hypersensitivity, and vomiting; if a significant reaction occurs, slow or interrupt the infusion; permanent discontinuation may be needed in severe reactions
