Half-life (triphasic) <5 min, 50-155 min, 23-85 hr; metabolized in liver; excreted in bile, feces; crosses placental, blood-brain barrier

INTERACTIONS

Decrease:
immune response—vaccines, toxoids

Decrease:
digoxin level—digoxin

Decrease:
vinCRIStine effect—CYP3A4 inducers (barbiturates, bosentan, carBAMazepine, efavirenz, phenytoins, nevirapine, rifabutin, rifampin)

Increase:
Neurotoxicity: peripheral nervous system products

• 
Do not use with radiation

• 
Acute pulmonary reactions: mitoMYcin c

 
Increase:
toxicity—CYP3A4 inhibitors (aprepitant, antiretroviral protease inhibitors, clarithromycin, danazol, delavirdine, diltiazem, erythromycin, fluconazole, FLUoxetine, fluvoxaMINE, imatinib, ketoconazole, mibefradil, nefazodone, telithromycin, voriconazole)

Avoid use with St. John’s wort

Drug/Lab Test

Increase:
uric acid

Decrease:
Hgb, WBC, platelets, sodium

NURSING CONSIDERATIONS
Assess:

• 
CBC, differential, platelet count before each dose; withhold product if WBC is <4000/mm
3
or platelet count is <75,000/mm
3
; notify prescriber; RBC, Hct, Hgb; may be decreased

• 
Bronchospasm:
more common with mitoMYcin

• 
Hepatic studies before, during therapy (bilirubin, AST, ALT, LDH) as needed or monthly

• 
Sensitivity of feet/hands, which precedes neuropathy

• 
Tumor lysis syndrome:
hyperkalemia, hyperphosphatemia, hyperuricemia, hypocalcemia; more common in leukemia, lymphoma; use alkalinization of urine with allopurinol, monitor electrolytes, renal function (BUN, urine, CCR, uric acid)

 

Black Box Warning:

Extravasation:
pain, swelling, poor blood return; if extravasation occurs, local inj of hyaluronidase and moderate heat to area may help disperse product

Intrathecal administration

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

• 
Effects of alopecia on body image; discuss feelings about body changes

• 
Buccal cavity q8hr for dryness, sores, ulcerations, white patches, oral pain, bleeding, dysphagia

• 
Symptoms indicating severe allergic reaction: rash, pruritus, urticaria, purpuric skin lesions, itching, flushing

Perform/provide:

• 
Brushing of teeth bid-tid with soft brush or cotton-tipped applicator for stomatitis; use unwaxed dental floss

Evaluate:

• 
Therapeutic response: decreased tumor size, spread of malignancy

Teach patient/family:
