Cyclophosphamide Dose by BSA

Calculate cyclophosphamide dose based on body surface area. IV dosing: 500-1500 mg/m2 every 3-4 weeks for lymphomas and solid tumours; oral: 1-2 mg/kg/day for autoimmune indications. Use mesna >= 600 mg/m2 for uroprotection.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate cyclophosphamide dose based on body surface area. IV dosing: 500-1500 mg/m2 every 3-4 weeks for lymphomas and solid tumours; oral: 1-2 mg/kg/day for autoimmune indications. Use mesna >= 600 mg/m2 for uroprotection

Each component has a specific meaning:

  • Body surface area — The body surface area recorded for the scenario being assessed.

Note: Interpret the cyclophosphamide dose result against the thresholds and context described above.

How to Use

Enter the body surface area for the scenario you are assessing. Calculate cyclophosphamide dose based on body surface area. IV dosing: 500-1500 mg/m2 every 3-4 weeks for lymphomas and solid tumours; oral: 1-2 mg/kg/day for autoimmune indications. Use mesna >= 600 mg/m2 for uroprotection. Use the cyclophosphamide dose result to inform your calculation.
