DOSAGE AND ROUTES
Calculator
Dosing with the Calvert equation

• Adult:
The total CARBOplatin dose in mg for adults may be calculated using the Calvert equation:

Total dose (mg) = target AUC × (GFR + 25)

• Children:
Calculate CARBOplatin dosage (mg/m
2
) in children:

Total dose (mg/m
2
) = target AUC × [(0.93 × GFR) + 15]

Black Box Warning:

To only be used by person experienced in the use of Chemotherapeutic products, in a specialized care setting

 

Black Box Warning:

Bone marrow depression:
CBC, differential, platelet count weekly; withhold product if neutrophil count is <2000/mm
3
or platelet count is <100,000/mm
3
; notify prescriber of results; calcium, magnesium, phosphate, potassium, sodium, uric acid, CCR, bilirubin; CCr <60 ml/min may be responsible for increased bone marrow suppression; assess frequently for infection

• 
Renal studies: BUN, creatinine, serum uric acid; urine CCr before, during therapy; I&O ratio; report fall in urine output to <30 ml/hr

• 
Monitor temp q4hr (may indicate beginning infection)

• 
Hepatic studies before, during therapy (bilirubin, AST, ALT, LDH) as needed or monthly; jaundice of skin, sclera; dark urine, clay-colored stools, itchy skin, abdominal pain, fever, diarrhea

 
Anaphylaxis:
hypotension, rash, pruritus, wheezing, tachycardia may occur within a few mins of use; notify prescriber after discontinuing product; resuscitation equipment should be available

• 
Delay dental work until blood counts have returned to normal; regular toothbrushes, dental floss, and toothpicks should not be used, use soft bristle toothbrush

• 
Peripheral neuropathy:
may be increased in geriatric patients

• 
Bleeding;
hematuria, stool guaiac, bruising, petechiae, mucosa or orifices; avoid all IM injections if platelets <50,000/mm
3

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

Evaluate:

• 
Therapeutic response: decreasing size of tumor, spread of malignancy

Teach patient/family:

• 
To report ringing/roaring in the ears; numbness, tingling in face, extremities; weight gain

• 
That impotence or amenorrhea can occur; that this is reversible after treatment is discontinued; to notify prescriber if pregnancy is suspected or planned; pregnancy (D), that contraception should be used if patient is fertile

• 
Not to breastfeed during treatment

To avoid OTC products with aspirin, NSAIDs, alcohol; not to receive vaccinations during treatment

 
To notify prescriber immediately of fever, fatigue, sore throat, bleeding, bruising, chills, back pain, blood in stools, dyspnea

• 
That hair may be lost during treatment; that a wig or hairpiece may make the patient feel better; that new hair may be different in color, texture

• 
To avoid crowds, persons with known infections; to avoid the use of razors, stiff-bristle toothbrushes
