• 
Bleeding, hematuria, guaiac, bruising or petechiae, mucosa or orifices q8hr

 

Black Box Warning:

ECG, ECHO, chest x-ray, MUGA, RAI angiography; assess ejection fraction before and during treatment; cardiotoxic may develop during treatment or months to years after treatment; use vigilant cardiac monitoring in MS

 

Black Box Warning:

Secondary acute myelogenous leukemia (AML) that can develop after taking this product

 

Black Box Warning:

Multiple sclerosis:
obtain MUGA, LVEF baselines; repeat LVEF if symptoms of CHF occur or if cumulative dose is >100 mg/m
2
; do not administer to patients who have received lifetime dose of ≥140 mg/m
2
or if LVEF <50% or significant LVEF

• 
Obtain pregnancy test for all women of childbearing age, even if birth control is used

• 
Rinsing of mouth tid-qid with water, club soda; brushing of teeth bid-qid with soft brush or cotton-tipped applicators for stomatitis; use unwaxed dental floss

• 
Increased fluids to 2-3 L/day unless contraindicated

Evaluate:

• 
Therapeutic response: decreased tumor size, spread of malignancy

Teach patient/family:

• 
To immediately report bleeding, dyspnea, possible infections, seizure, jaundice, fever, cough, or dyspnea

• 
To avoid hot foods or those with citric acid, rough texture

• 
To report any bleeding, white spots, ulcerations in mouth; to examine mouth daily
