Usual Adult Dose for Hodgkin's Disease

As a single agent:

Initial dose: Single or divided doses of 2 to 4 mg/kg/day orally for one week (to minimize the nausea and vomiting experienced by a high percentage of patients beginning therapy)
Maintenance dose: 4 to 6 mg/kg/day orally until maximum response is obtained or until the white blood count falls below 4000 or the platelets fall below 100,000; when maximum response is obtained the dose may be maintained at 1 to 2 mg/kg/day orally
Discontinue therapy for hematologic or other toxicity until satisfactory recovery, then resume therapy (at the discretion of the physician based on patient evaluation and laboratory studies) at 1 to 2 mg/kg/day

In combination with other anticancer drugs:

The dose of this drug should be reduced (e.g., in the MOPP regimen, the dose is 100 mg/m2/day for 14 days)

Comments:

Dosing given here is manufacturer suggested. Local and institutional protocol should be consulted.
Doses should be based on the patient's actual weight; however, the estimated lean body mass (dry weight) is used if the patient is obese or if there has been a spurious weight gain due to edema, ascites, or other forms of abnormal fluid retention.

Use: In combination with other anticancer drugs for the treatment of Stage III and IV Hodgkin's disease; this drug is used as part of the MOPP (nitrogen mustard, vincristine, procarbazine, prednisone) regimen
