What is Carboplatin used for?

Carboplatin is used to treat cancer. It interferes with the growth of cancer cells and slows their growth and spread in the body.

Carboplatin is used together with other cancer medications to treat ovarian cancer.

How should I take Carboplatin?

Carboplatin is usually given by infusion into a vein (intravenously-IV) over at least 15 minutes by a healthcare professional.

The dosage is based on your medical condition, body size, and response to therapy. In general, courses of carboplatin treatment should not be given more often than once every 4 weeks.

How do I store Carboplatin?

Unopened vials of Carboplatin Injection are stable to the date indicated on the package when stored at 25°C; excursions permitted from 15°– 30°C. Protect from light. Carboplatin Injection multidose vials maintain microbial, chemical, and physical stability for up to 14 days at 25°C following multiple needle entries. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Solutions for infusion should be discarded 8 hours after preparation.

There may be different brands of Carboplatin that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush Carboplatin down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.

Side effects

What side effects can occur from Carboplatin?

Stomach pain, body aches/pain, diarrhea, constipation, weakness, nausea, and vomiting may occur. Nausea and vomiting can be severe in some patients but usually go away within 24 hours of treatment. Drug therapy may be needed to prevent or relieve nausea and vomiting. Not eating before your treatment may help relieve vomiting. Changes in diet such as eating several small meals or limiting activity may help lessen some of these effects. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Temporary hair loss may occur. Normal hair growth should return after treatment has ended.

What is the dose of Carboplatin for an adult?

Usual Adult Dose for Ovarian Cancer

Single agent therapy for use in the treatment of recurrent ovarian cancer:

360 mg/m2 by intravenous injection on day 1 every 4 weeks (alternatively, the carboplatin dose may be calculated by the Calvert formula below). In general, however, single intermittent courses of carboplatin should not be repeated until the neutrophil count is at least 2000 and the platelet count is at least 100,000.

Combination therapy (with cyclophosphamide) for use in the treatment of advanced ovarian cancer (an effective combination for previously untreated patients):

  • carboplatin 300 mg/m2 by intravenous injection on day 1 every four weeks for six cycles (alternatively, the carboplatin dose may be calculated by the Calvert formula below).
  • cyclophosphamide 600 mg/m2 by intravenous injection on day 1 every 4 weeks for six cycles.

Intermittent courses of carboplatin in combination with cyclophosphamide should not be repeated until the neutrophil count is at least 2000 and the platelet count is at least 100,000.

Calvert formula: Another approach for determining the initial dose of carboplatin is the use of the following mathematical formula, which is based on a patient’s preexisting renal function or renal function and desired platelet nadir. (Renal excretion is the major route of elimination for carboplatin.) The use of this dosing formula, as compared to empirical dose calculation based on body surface area, allows compensation for patient variations in pretreatment renal function that might otherwise result in either underdosing (in patients with above average renal function) or overdosing (in patients with impaired renal function).

A simple formula for calculating dosage, based upon a patient’s glomerular filtration rate (GFR in mL/min) and carboplatin target area under the concentration versus time curve (AUC in mg/mL/min), has been proposed by Calvert.

Calvert formula for carboplatin dosing: Total Dose (mg)=(target AUC) × (GFR + 25)

Note: With the Calvert formula, the total dose of carboplatin is calculated in mg, not mg/m2 .

The target AUC of 4-6 mg/mL/min using single agent carboplatin appears to provide the most appropriate dose range in previously treated patients.

In order to avoid potential toxicity due to overdosing, if a patient’s GFR is estimated based on serum creatinine measured by the standardized Isotope Dilution Mass Spectrometry (IDMS) method rather than using an actual GFR measurement, a capping of the dose of carboplatin for the desired exposure (AUC) has been recommended.

Maximum carboplatin dose (mg) = target AUC (mg x min/mL) x (150 mL/min)

The maximum dose is based on a GFR estimate that is capped at 125 mL/min for patients with normal renal function. No higher estimated GFR values should be used.

For example:

For a target AUC = 6, the maximum dose is 6 x 150 = 900 mg

For a target AUC = 5, the maximum dose is 5 x 150 = 750 mg

For a target AUC = 4, the maximum dose is 4 x 150 = 600 mg

Usual Adult Dose for Cervical Cancer

(In combination with other chemotherapeutic agents as a part of the BIC regimen)

200 mg/m2 IV on day 1

The cycle is repeated every 21 days.

Renal Dose Adjustments

Patients with Impaired Kidney Function:

Patients with creatinine clearance values below 60 mL/min are at increased risk of severe bone marrow suppression. In renally-impaired patients who received single agent carboplatin therapy, the incidence of severe leukopenia, neutropenia, or thrombocytopenia has been about 25% when the dosage modifications in the table below have been used.

If a patient has a baseline creatinine clearance of 41-59 mL/min, then the recommended dose for this patient on day 1 is 250 mg/m 2.

If a patient has a baseline creatinine clearance of 16-40 mL/min, then the recommended dose for this patient on day 1 is 200 mg/m 2.

The data available for patients with severely impaired kidney function (creatinine clearance below 15 mL/min) are too limited to permit a recommendation for treatment.

These dosing recommendations apply to the initial course of treatment. Subsequent dosages should be adjusted according to the patient’s tolerance based on the degree of bone marrow suppression.

Dose Adjustments

Pretreatment platelet count and performance status are important prognostic factors for severity of myelosuppression in previously treated patients. The suggested dose adjustments for single agent or combination therapy shown in the table below are modified from controlled trials in previously treated and untreated patients with ovarian carcinoma. Blood counts were done weekly, and the recommendations are based on the lowest posttreatment platelet or neutrophil value.

Platelets Neutrophils Adjusted Dose (from prior course)

> 100,000 > 2000 125%

50-100,000 500-2000 No Adjustment

< 50,000 < 500 75%

*Percentages apply to carboplatin as a single agent or to both carboplatin and cyclophosphamide in combination. In the controlled studies, dosages were also adjusted at a lower level (50% to 60%) for severe myelosuppression. Escalations above 125% were not recommended for these studies.


Carboplatin is contraindicated in patients with severe renal impairment (CrCl less than 20 mL/min).

What is the dose of Carboplatin for a child?

Usual Pediatric Dose for Malignant Disease (Not approved by FDA)

Pediatric Calvert Formula:

Total dose (mg) = [Target AUC (mg/mL/min)] x [GFR (mL/min) + (0.36 x body weight in kg)]

Note: With the Calvert formula, the total dose of carboplatin is calculated in mg, not mg/m2 .

The target AUC varies with the number of agents in the regimen and if the patient has been treated previously or not.

Solid Tumor:

300-600 mg/m2 once every 4 weeks.

Brain Tumor:

175 mg/m2 once weekly for 4 weeks with a 2 week recovery between courses. The dose should then be adjusted based on platelet and neutrophil count values.

Bone Marrow Transplant Preparative Regimen:

500 mg/m2/day for 3 days.

The dosage has not been established in pediatric patients. It may be unsafe for your child. It is always important to fully understand the safety of the drug before using. Please consult with your doctor or pharmacist for more information.
