BSA & Capecitabine Dose Calculator

Calculates BSA from height and weight (or uses a given BSA) and suggests Capecitabine doses and tablet counts for two clinical scenarios.

Inform BSA or Weight and Height and hit the Calculate button

If BSA is provided, height and weight are not required.

If BSA is unknown, let's calculate it first using height and weight.

If BSA is not provided, BSA will be calculated using the Mosteller formula.

This is the BSA that will be used for dose calculations.

Scenario 1 – Capecitabine with chemoRT

Regimen: Capecitabine 825 mg/m² PO BID, Monday–Friday, on each day that RT is given throughout the duration of RT.

Preselected value is 30. Change if needed.

Scenario 2 – Capecitabine (systemic)

Regimen options: dose per day based on BSA (total daily dose).

Total daily dose; the calculator will split tablets into morning and night.

Exact tablets/day (with decimals) will be displayed; prescription uses the rounded value.

Scenario 1 – chemoRT results
Morning Night Units
Capecitabine dose per administration — — mg
Number of tablets per administration — — 500 mg tablets
Total tablets for full RT course — 500 mg tablets
BSA used — m²
Scenario 2 – Capecitabine (systemic) results
Morning Night Units
Capecitabine dose per dose (AM/PM) — — mg
Number of tablets per dose — — 500 mg tablets
Total tablets per day (exact, not rounded) — 500 mg tablets
Total tablets per day (rounded for prescription) — 500 mg tablets
Total tablets per 14-day cycle (rounded) — 500 mg tablets
BSA used — m²
For adults only. Capecitabine tablets assumed to be 500 mg each. This tool is for educational support and does not replace clinical judgment.
